Summary Co-ordinated plant physiological research was conducted during 2012 kharif season through field experiments at six AICRIP centers (Coimbatore, Maruteru, Pantnagar, Pattambhi, Rewa and Titabar), two ICAR institutions ( DRR, Hyderabad and CRRI, Cuttack) and five voluntary centers (BHU Varanasi, NDUAT Faizabad, PJNAR, Karaikal, Zonal drought paddy station, Hatwara and RARS Karjat). Photothermic indexing, radiation use efficiency, influence of silicon solubilizers on induced stress tolerance in rice genotypes, Screening elite rice genotypes for drought tolerance (Rainfed Upland) , Physiological studies on near isogenic lines for submergence tolerance and Evaluation of rice genotypes for terminal heat tolerance suitable for future climate were conducted at these twelve locations. Salient findings of the experimental results, in brief, are presented below. 6.1. a) PHOTOTHERMIC INDEXING:

The experiment was conducted at 7 geographical locations and the crop was sown up

to 15 days early so as to expose the crop to differential photo thermal periods. The experiment was laid in split plot mode with three replications and under normal cultural practices with two dates of planting viz., early and normal sown sets. The experimental material comprises 2 cultures of AVT 2 ME 2010 (relative photo insensitive cultures identified in physiology AICRIP trials 2010-12) and 21 AVT 1 ME cultures, 5 RP series cultures, US-312, US-382 cultures ( Hybrids) and 4 checks (DRRH-3, IR 64, MTU 1010 and PR-113). The objective of the photothermic indexing is to quantify the day degree and nyctoperiod requirements in rice cultures across the geographical zones so as to identify better donors for developing rice that would be suitable to wider climatic adaptability. Based on the earlier PTI trials conducted under AICRIP, critical CNP for medium duration cultures at PI (850-1000) (10 cultures including DRRH-3 check) under early and (8 including DRRH-3) under normal planting had met the required nyctoperiod. Similarly at 50% flowering was (1000-1200) 17 cultures including check ( PR-113) under early and 15 cultures including ( DRRH-3) under normal planting were within the limits of recommended CNP. There were only 7 common entries including checks that had fulfilled CNP at both stages and within the critical limits under both the planting dates. RP 4919-40 is the only entry which met CNP periods under both PI and 50% flowering time. As reported earlier, CDD (1600-1700) is more important at the time of maturity. Accordingly, under early planting date CDD observed to be within the limits for 12 experimental cultures and one check ( MTU 1010) under early planting date and 15 cultures including checks ( DRRH-3 and PR-113) under normal planting dates. Few cultures that are common at both planting dates were IET 22567, IET 22568, IET 22603, and US-382. IET 20924 identified earlier under this program continued to be superior this year. Also other cultures, IET 22218, IET 22569, RP-4918-16630 and check DRRH-3 were found to be having relative photo insensitivity to planting date.


6.2

b) RADIATION USE EFFICIENCY OF GENOTYPES: The study was conducted at three locations with an objective to understand why certain genotypes perform better than others under different planting dates? Establishing a relationship between RUE and PTI would be of immense importance for stable yields as RUE is related to the interception of solar radiation directing the photosynthesis process and partition towards total dry matter (TDM) accumulation, a determinant factor for enhancing crop yield.. RUE values at maximum tillering (PI) stage were found to be superior at DRR location and greater than 1 for most of the cultures while none of the cultures had exceeded one at CBT and at PNR locations. Cultures, IET 21542, IET 22212, IET 22240, IET 22386, IET 22500, IET 22552, IET 22551, IET 22563,IET 22 565, IET22568,IET22579,IET22592, RP-4918-16630, RP-4916-458,RP-4919-40 PR 113, US-312 and IR 64 had RUE more than 1. From PI to flowering and flowering to maturity there was a reduction in the RUE and genotypes differed significantly with respect to TDM accumulation, RUE and grain yields under two different planting dates. All these estimated parameters including that of photosensitivity resulted in identifying the best five entries which exhibited superior and stable performance.

6.2. Influence of silicon solubilizers on induced stress tolerance in rice genotypes

A trial on the influence of silicon solubilizer and carrier molecule on induced stress tolerance was conducted at 9 locations in a split plot design with three replications. Ten popular rice cultures, comprising 5 each of varieties and hybrids were used as experimental materials. A total of 50 ml Sodium silicate was used as spray at PI and flowering stages while 20 gms carrier molecule, imidazole ( silicon solubilizer) dissolved in water was supplemented through irrigation. The mean LAI reached to 5.71 due to influence of treatments while in control it was 5.55 only. Carrier molecule application had significant influence on silicate application (5.85 and 5.72 respectively. TDM increase from tiller to flowering was significant at HAT, MTU, PNR due to silicon carrier and also sodium silicate. Grain yield and its components such as filled grain number per panicle, 1000 grain weight (g), grain yield and harvest index ( HI) were found to be superior under the treatments at RWA and TTB locations. Amongst the genotypes, as high as (Sampada) 70g/m2 to (Nagarjuna) 28g/m2 grain yield increase in varieties and in hybrids, 100g/m2(PHB-71) to 35g/m2 (KRH-2) respectively contributed by better partitioning ability due to silicon application.

6.3. Evaluation of rice genotypes for terminal heat tolerance

Rice is highly susceptible to heat stress, particularly during the reproductive and ripening stages. A coordinated trail was initiated at seven AICRIP centres to investigate the influence of post-anthesis heat stress on yield and related components and to identify genotypes which could be used as donors and imparting high temperature tolerance. A total of 22 entries comprising of 9 AVT-2 ME2011 entries, 5 released varieties and 8 popular hybrids (APPENDIX) were included in the trial. Heat stress was imposed in the field immediately after panicle initiation stage by enclosing the field grown crop with a make shift locally fabricated polythene tent. Based on grain yield and other yield related parameters IET-221116, IET-22218, IET-21577 and IET-21411showed relative tolerance and among hybrids PA-6444 performed well and in case of popular varieties MTU-1010 and IR-64 showed tolerance to post-anthesis high temperature. All these entries performed better than N-22 which is a national check for heat tolerance. 6.4. Screening of elite rice cultures for drought tolerance:

In India the upland rainfed rice is cultivated in 6 million ha of area accounting for 1.4% of total rice area of the country. Drought is the most important constraint affecting the rice yield in upland rice cultivation. Drought tolerance characteristics of selected rice culture were assessed at six AICRIP centres (BHU, CTK, PTB, REWA, HAT). A total of 72 rice cultures, consisting of 18 AVT-VE-DS, 6 AVT-2-E-TP, 8 AVT1-E-TP and 36 IVT-E-DS cultures. along with Anjali, Tulasi, Sahabhagidhan and PA-6129. Based on the grain yield recorded under rainfed condition and drought indexes ( DSI and YS), IET 23344, IET-22767, IET-22744, IET-22061, IET 23377, IET-23381, IET-23345 and IET-22747 were identified as suitable to upland rainfed condition. 6.5. Submergence Tolerance in Rice: Submergence tolerance:

Submergence tolerance was studied at two locations Cuttack (Orissa) and Titabar (Assam) with an objective to find the influence of phosphorus application (20, 40, 60 and 80 kg/ha) on near isogenic rice lines having sub 1 gene. The experimental material consists of Swarna, IR-64, CR 1009 and Saavithri with and without Sub-1 introgression. These cultures were subjected to 14 days submergence and the data were recorded for growth and yield attributes along with the control. Among the cultivars CR1009 sub-1 was better in control and under submergence Swarna sub-1 had a better yield advantage which was significant among the three cultivars. Yield and biomass under submergence was highest at 40kg/ha at both the locations.. Phosphorus levels under submergence had no significant influence on yield and biomass. At CRRI Swarna sub-1 and at Titabar IR-64 sub-1 were found to be superior in terms of growth yield and yield attributes at 40 kg phosphorus per hectare under submergence conditions.

6.1.1. a) Photothermic Indexing:

Locations: BHU, CBT, DRR, FZB, HAT, KRK, MTU, PNR, PTB, TTB, UMM

The objective of the photothermic indexing is to quantify the day degree and

nyctoperiod requirements in rice cultures across the geographical zones so as to identify

better donors for developing rice that would be suitable to wider climatic adaptability. Two

strategies, one utilizing natural diversity of the country to screen large number of cultures in

an inexpensive way to narrow down the donor lines through AICRIP system and another, by

adapting different planting dates in these diverse geographical locations so as to identify

stable rice cultures for the purpose of fine tuning and hasten the breeding initiatives to

develop climate resilient rice genotypes. Photothermic indexing trial under AICRIP is

focused to identify the donor lines which have relative lower photosensitivity. Eleven of the

locations opted for this trial while at 7 locations the complete data inputs could be recorded

required for functioning of the model. The complete weather records and crop parameters, for

the remaining four locations is partial or only one set of data hence, CDD and CNP could not

be computed (Table 6.2.12) hence the data from these locations not included in the present

text.

The experiment was laid in split plot mode with three replications and under normal

cultural practices with two dates of planting viz., early and late sown sets. The experimental

material comprises 2 cultures of AVT 2 ME 2010 (relative photo insensitive cultures

identified in physiology AICRIP trials 2010-12) and 21 AVT 1 ME cultures, 5 RP series

cultures, 2 US series cultures ( Hybrids) and 4 checks (DRRH-3, IR 64, MTU 1010 and PR-

113). Quantification of the thermal and nyctoperiods in terms of the weather such as

temperature, relative humidity and latitudes etc as described (Annual Progress Report Vol 3:

2004/05) were fed in to the model for computing Cumulative Degree Days (CDD) and

Cumulative Nycto-Periods (CNP). The model requires additional crop parameters such as

phenology particularly panicle initiation, 50% flowering, and maturity stages as inputs. Input

observations crop phenology, node number, total dry matter production and grain yield at

both the planting dates for calculating the CDD and CNP at different stages for genotype

wise, location wise and across the locations so as to identify the relative photo insensitivity.

Crop Parameters: Time taken for the crop to reach PI, 50% flowering and maturity

at each of the location is presented in tables (6.1. 1- 6.1.3) and also the node number (Table

6.1.4). The number of days taken to reach PI stage irrespective of locations was 75,

minimum and maximum varying between 69 and 86. Two of the cultures IET 21542, IET


6.5

22240 and all the four cultures of RP series took more than 80 days. Amongst the locations,

at DRR the relative period for PI was more (mean 93 and 90 days) while at MTU it was as

low 57 days under both planting days. Checks reached PI stage almost 4 days earlier than the

test entries at all the locations except at FZB. Within a period of 20 days, (Mean 93 days) all

the cultures reached 50% flowering. DRR, FZB and PNR took longer time (>100 days) than

at remaining locations. Both checks and the test entries were similar in their response under

both planting dates. Though, only three cultures i.e IET 21542, IET 22240 and RP -4918-7k

had more than 100 days for arriving to the 50% flowering stage, as higher as 138 (RP-4919-

458) to as lower as 77 days ( IET 22552) indicating the differences with reference to the

influence of sowing time. The crop matured at MTU within 117 days under normal sown

date while 144 days at DRR under early sowing date with amean of 129 days. Here too a

wide variation of 107 days (IET 22552) and RP-4919-458 and RP-4919-24k (158 days)

observed. The total number of nodes produced before reaching to the PI stage is provided did

not vary significantly at various locations with respect to the date of planting (table 6.1.4)

which varied between 3-9 and could be due to sampling error.

Total Dry Matter (TDM) : TDM produced at tiller, 50% flowering and maturity are

provided in Tables 6.1. 5 -6.1.7. The mean TDM recorded irrespective of planting dates, at PI,

50% flowering and maturity were 217, 963 and 1538 g.m2 respectively. However, due to the

variation in local weather situation, the test entries responded differentially to the planting

dates at these locations. For instance, at the tiller stage, the TDM very low at PTB ( 59 and 71

g/m2 at early and normal planting) to as high as 362 and 306 g/m2 at CBT which are not

geographically apart. In the other 5 locations the TDM was comparable and moderate though

there were genotypic differences existed. The trend with respect to checks was in similar

lines as that of test entries.

IET 22084 recorded maximum (CBT 442 g/m2) IET 22551 recorded minimum (PTB:

37g/m2) TDM at early planting date respectively. At least 8 of the entries recorded more than

211 the mean TDM at tiller stage. Checks on the other hand had 10 g/m2 more biomass and

DRRH-3 and MTU 1010 had more biomass at this stage. At 50% flowering stage, all those

entries which recorded higher TDM did not maintain similar biomass accumulation. Thus the

initial vigour need not carried further due to the factors other than genetic potentials and the

weather seems to be taking over. Location wise, DRR and PNR were at par where higher

TDM recorded while at CBT and MTU it was lower.

The maximum and minimum were both from normal planting dates i.e.1763 g/m2 (PNR US

382) and 509 g/m2 (CBT RP-4918-7k). Among the test entries 11 and one of the check i.e


6.6

DRRH-3 had > 1000g/m2 irrespective of planting dates and locations. The trend did not differ

with checks at these locations. Similarly at maturity stage, 11 entries and 2 checks had TDM

> than 1540 g/m2. At BHU and PTB locations maximum and minimum TDM s recorded in

these test entries. Similar was the trend in checks.

Grain yield : Grain yields obtained under early and normal plantings presented in

Table 6.1.7, The mean GY of test entries was 614g/m2 not very much different from that of

checks (605 g/m2) irrespective of location and planting dates. At least, 11 test entries and 2

checks (DRRH-3, and PR-113) had GY >615. The maximum and minimum grain yields

recorded were 1017 g/m2 ( RP-4919-40 at CBT early) and minimum 154 ( IET 22552 and

IET 22563) at PTB under normal planting date. Thus a widest grain yields and TDM of

genotypes was evident with respect to location, genotype and planting date interactions and

are further reflected in the Harvest Index (HI%).

The HI recorded at PTB appears to be very high when compared to the TDM and the

GY which has exceeded to that of 50% and therefore, needs further verification. On the other

hand, BHU it is very low. Thus, only 5 of the locations have HI values within the limits and

also the corresponding checks. These differences arose due to environmental variation

particularly at the period between the PI to maturity as the initial vigour of the growth were

mor or less recovered by the time of maturity resulting in narrowing down of the TDM and

grain yield. However, stability of the genotype in terms of TDM and yield in a given weather

situation was assessed separately and discussed under RUE while that of photothermic

indexing is related to photosensitivity.

Model parameters: Weather data of the seven locations is provided in Appendix :

and the model derived parameters such as CDD and CNP stage wise and also the genotype

are presented in Table 6.1.10. Summary of the experimental means for CDD and CNP

parameters stage wise are presented in 6.1.11.

The results presented in the above tables are briefly described as under. Under early

planting, the experimental cultures reached PI stage 5 days later than under normal planting

date, similar to that of the checks. The TDM at this stage, was 10-15 g lower in spite of the

delay in PI stage under early planting date. To reach 50% flowering also 3 and 5 days

delayed between the early and normal planting dates occurred with a mean of 948 and 934 g

of TDM recorded in experimental cultures and checks respectively. Till this stage most of the

rice cultures had maintained lower biomass relative to the control. Interestingly by the time of

maturity TDM was higher under early planting dates in both IET cultures and checks

compared to the normal planting date. Based on the Photothermic Indexing (PTI) conducted

under AICRIP, critical CNP for medium duration cultures at PI (850-1000) ( 9 and 1 DRRH-

3 check) under early and (7+1 DRRH-3) under normal planting had met the required

nyctoperiod.

Of these 7 are common test entries at both the planting dates. Similarly at 50%

flowering was (1000-1200) 16+1 check ( PR-113) under early and 14 +1 ( DRRH-3) under

normal planting within the limits of recommended CNP with 7 common entries under both

the planting dates. RP 4919-40 is the only entry which met CNP periods under both PI and

50% flowering time. As reported earlier, CDD (1600-1700) is more important at the time of

maturity. Accordingly, under early planting date CDD observed to be within the limits for 12

experimental cultures and one check ( MTU 1010) under early planting date and 13 +2

checks ( DRRH-3 and PR-113) under normal planting dates and common entries at both

planting dates were IET 22567, IET 22568, IET 22603, and US-382. PI stage. In general, at

PI and flowering stages, the CNP requirement though was within the limits under both

planting dates, under early situation, the CNP was more nearer to maximum. Similarly, CDD

at maturity was within the critical limits under both planting dates of the experimental

cultures while it was lower under normal planting dates in checks.

Thus, the photoperiod and nyctoperiod requirement of experimental cultures was

largely met which was correlated with yields obtained of cultures and checks to a larger

extent. However, genotypic variations with reference to the CDD and CNP requirement at

each of the stage varied widely. Of the 30 experimental entries tested, stage wise CNP and

CDD were calculated across the locations. In addition to the culture that has been included

based on the performance of previous years additional IET cultures i.e IET 20924 continued

to be in the limits indicating the stability and of possible 6 ( 2 each of PI and 50% flowering

and for CNP and 2 for CDD) situations, at four of the situations the culture met the

requirement. Additional cultures, IET 22218, IET 22569, RP-4918-16630 and check DRRH-

3 were found to be having relative photo insensitivity to planting date. Other cultures IET

22567, IET 22568, IET 22603 and hybrid US-382 and check PR-113 found to perform better

either early or normal planting dates. Though some of the cultures had higher yields under

early planting dates the developmental plasticity was not suiting for normal planting resulting

unstable yields indicating that these have relative photosensitivity.

Thus, the much needed information on photosensitivity dependent yield could be

predicted provided planting date, PI stage and weather parameters are the most critical based

on which the photosensitivity could be determined in rice cultures.

b) RADIATION USE EFFICIENCY OF GENOTYPES

Locations: CBT, DRR and PNR

The trials on Photothermic Indexing are related to flowering and its utility is to

identify the relative photosensitivity or insensitivity in rice crop but it may not necessarily

relate to enhancing crop yields. On the other hand, Radiation Use Efficiency (RUE) is related

to the interception of solar radiation directing the photosynthetic process towards total dry

matter (TDM) accumulation, a determinant factor for enhancing crop yield. In view of this,

for the past two years RUE trials are being conducted under AICRIP physiology program

with separate entries. As one of the connecting link to arrive for identifying the cultures under

PTI if extended might be more useful in identifying rice cultures with stable yields. In view

of this, RUE studies under early and late planting condition along with TDM production had

been conducted using the solar radiation data and only three locations had the information of

solar radiation measurements during crop growth. The major objective of this trial was is

there a change in rice genotypes for efficiency in dry matter production and radiation use

efficiency under normal and late planting. About thirty four cultures were evaluated as

described under PTI. Radiation use efficiency was estimated using ORYZA 2000 crop

growth model based on the TDM recorded at phenological stages and other meteorological

parameters required for the model.

TDM of the 3 locations for two planting dates, stages and locations is presented in

Table 6.1.13 and Table 6.1.15 while their corresponding RUE tables in Table 6.1.14 and

6.1.16 respectively. Significant differences were observed for RUE at panicle initiation

amongst different rice genotypes and across locations under early and normal planting dates.

At DRR location the rice crop exhibited greater RUE values followed by PNR while at CBT

the RUE was lower. However, TDM was found to be in reverse order where genotypes had

higher TDM values at CBT followed by PNR and DRR. However, RUE values were within

the reported limits published for rice crop. The TDM (g.m2) recorded at tiller stage varied

significantly amongst the genotypes. The interaction Location x genotypes was also found to

be significant. The mean TDM recorded at CBT 362 and 306 g/m2, DRR 177 and 251 g/m2

and PNR 274 and 282 g/m2 respectively under early and late planting situation. There existed

significant genotypic differences at this stage. Similarly, the TDM recorded at 50% flowering

showed significant differences amongst the genotypes. The interaction between location and

genotypes was also found to be significant. The mean TDM recorded for all genotypes were

676 and 635 g/m2 (CBT), 1194 and 1138 g/m2 (DRR) and 1223 and 1468 g/m2 (PNR) under

early and normal planting conditions. While at maturity stage it was 1816 and 1900 g/m2

(CBT), 1442 and 1292 g/m2 (DRR) and 1728 and 1743 g/m2 (PNR) under the early and

normal planting situation. On the other the RUE values at tiller (PI) stage were found to be

superior at DRR location and greater than 1 for most of the cultures while none of the

cultures had exceeded one at CBT and at PNR cultures, IET 21542, IET 22212, IET 22240,

IET 22386, IET 22500, IET 22552, IET 22551, IET 22563,IET 22 565, IET22568, IET22579,

IET22592, RP-4918-16630, RP-4916-458, RP-4919-40 PR 113, US-312 and IR 64 had RUE

more than 1. Normally, RUE does not exceed one for rice crop at the PI stage unless

otherwise very strong solar radiation received during the season. High solar radiation

situation reaching the earth’s surface, at the initial crop growth stage often plays a negative


6.10

role and accumulation of TDM is often reduced. Genotypes with RUE value of 1 is

considered to be efficient in several of the crop species. Considering this, at least 14 of the

cultures were found to have good potential in terms of TDM and also RUE in a desirable

range. Between the tiller to 50% flowering stage, since the solar radiation interception period

is small, at all the three locations the RUE values were found to be within a range of(<0.2)

and the changes were not very different in the genotypes as well as locations. Marginally

higher RUE recorded at CBT. Once the PI stage reached, the number of days to taken for

flowering will be smaller though a variation occurred between the different planting dates.

The TDM accumulation measured as difference between 50% flowering to maturity was as

low as 300 (g/m2) at CBT to as high as 1200 g/m2 at PNR location. Thus, at seedling to tiller

stage CBT had recorded low RUE as well as biomass compared to other two locations. By

maturity stage, the trends were reversed where in greater TDM was accumulated in a short

interval between 50% flowering to maturity is surprising at CBT as normally, partition of dry

matter towards grain filling results in reducing the TDM as happened in the DRR and PNR

location. In view of this, the CBT results are subjected to further verification. The trend was

similar with respect to checks also. Genotypic variation with reference to RUE under normal

planting (Table. 6.2.16) confirms the basis of superior performance of the some cultures that

were shown to exhibit relative superiority in photothermic indexing. For instance, the best

five entries exhibited superior and stable performance (Table 6.1.17) for various characters in

terms of RUE and TDM and also confirms the relative photosensitivity. Reasonable

genotypic performance based on the weather and crop phenology under different sets of

sowing dates for photo sensitivity with appreciable RUE could be leading to identifying the

donors for crop improvement.

6.2. Influence of silicon solubilizers on induced stress tolerance in rice genotypes Locations: CBT, DRR, MTU, HAT, PNR, PTB, RWA, TTB and KJT

Rice is able to accumulate Si up to 10% of dry weight in the shoots; this concentration

is several-fold higher than those of the essential macronutrients, including nitrogen,

phosphorus and potassium. High accumulation of Si is required for maximal sustainable

rice production. Most of the beneficial effects of Si are realized through Si deposition in

cell walls of the epidermal surfaces of leaves, stems and hulls. Si is taken up in the form of

silicic acid and translocation from the roots to the shoots in the same form. It is finally

deposited in the cell wall materials as a polymer of hydrated amorphous silica, forming

silica-cuticle double layers and silica-cellulose double layers in the shoot. Deposition of Si

enhances the strength and rigidity of cell walls and thus increases the resistance of plants to

various stresses. Silicon is one of the beneficial element and its effects are best realized

when the plants are under stress situations. In view of the recent information on importance

of silicon nutrition on rice in counter acting stress and the low soil solubility due to various

factors such as pH, temperature, soil types, soil microsphere both solubility as well as

uptake are influenced. Application of silicon solubilzer in the form of carrier molecule i.e.

imidazole (T2 : referred as carrier here after) to solubilize and make it available to rice

plants and also sodium silicate (T1 :referred as silicate here after) liquid (mono silicilic

acid) was taken up at 9 locations. The experiment was laid in a split plot design mode with

three replications. Ten popular rice cultures, 5 each of varieties and hybrids used as

experimental material with all normal cultural practices followed for rice cultivation except

for the treatments as detailed above. 15 ml and 35 ml of Sodium silicate was mixed with 10

liter water and sprayed at vegetative stage and at PI stage respectively. The carrier

molecule, imidazole (10g) dissolved in water and supplemented through irrigation water at

vegetative and PI stages. Thus, the rice plants received a total of 50 ml sodium silicate (T1)

and 20 gm imidazole (T2) in two split doses in its life cycle. This being the first year study

stress situation was not imposed and at few locations the carrier was also sprayed after

dissolving the element in water. Observations recorded were plant phonological dates, leaf

area index, leaf and stem dry matter production, yield and yield components. Also, scoring

for blast and yellow stem borer incidence was to be recorde but this season there was no

such incidence reported from the centers hence, only physiological observations are

discussed.


6.37

Phenology:

Silicon solubilizer application did not significantly bring any change either in the days

to 50% flowering or maturity dates (mean 95 and 122 days respectively) in the test entries

except minor variation at DRR and HAT locations ( Table 6.2.1). All the ten genotypes

belonged medium duration group and the days taken for flowering varied between 83 (HAT)

to 101 (DRR) and 112 (HAT) and 133 (DRR) days to reach 50% flowering and for maturity

respectively.

Tiller stage:

At tiller stage, the observations recorded were presented in Tables 6.2.2- 6.2.4 The

experimental means for leaf area index (LAI), leaf and culm weights recorded were 2.78, 131

(g) and 191 (g) respectively. With the application of silicate as well as carrier molecules there

was an increase in the mean leaf area from 2.67 to 2.86. However, the increase in leaf and

culm the treatment effects were found to be negligible though, location and genotypic

significances were noticed. For instance, all the five hybrids had better initial vigour and

treatments resulted in enhancing the LAI and leaf weights but the same was not true with

reference to the varietal response. Thus, a mean LAI at tiller stage in control was 2.61 which

increased to 2.86 with carrier application was evidenced. The mean increase in LAI was

relatively more in hybrids compared to the varieties and is significant at MTU, PNR and

REWA locations.

Flowering stage:

The above parameters also recorded at flowering stage and presented in Tables 6.2.5-

6.2.7. With increased duration naturally an increase in the LAI, leaf and culm weights would

be forecasted but the degree of treatment and genotypic variations were with reference to the

these parameters was found to be significant. The experimental mean in LAI reached to 5.71

while in control it was 5.55 only. Carrier molecule application had significant influence

relative to silicate application (5.85 and 5.72 respectively). Once again, the consistently

significant influence was recorded at the same three locations viz., MTU, PNR and RWA.

The influence was concomitant with increases in leaf and culm weights respectively.

Interestingly, the initial vigour exhibited by hybrids appears to be reducing with time where

as varieties catching up and expanded the leaf area more vigorously there by the mean

differences were not to be varying between the two groups. Also, at this stage treatment

influence was more prominent on culm weight preparing the crop towards maturity. However,

the growth response due to silicate seems to be as good as that of carrier molecule treatment.

Total Dry Matter ( TDM) at growth stages:


6.38

TDM (both leaf dry weight and culm dry weight) at maximum tiller, 50% flowering

and maturity varied widely among the genotypes ( Tables 6.2.8-6.2.10). The experimental

means at these three stages are 231, 889 and 1359 (g) respectively. At tiller stage, the

differences were minimal amongst the genotypes but at 50% flowering time and at maturity,

the TDM seems to be influenced by the treatments as well. For instance, Varadhan which had

783 (g) under control exhibited additional biomass of 100 (g) under carrier molecule

treatment while Shanthi accumulated 150 (g) biomass under the influence of silicate. Hybrids

did not respond in terms of biomass accumulation though, at 3 locations some response was

evident at this stage. TDM increase from tiller to flowering was significant at HAT, MTU,

PNR due to silicon solubilizer as well as sodium silicate application. However, the response

at maturity stage gradually disappeared at maturity stage. An increase of 78 (g) biomass

accumulation was the ultimate result at maturity. Thus,the vigorous response of hybrids

dissipated and both varieties and hybrids had reached similar biomass accumulation

irrespective of treatments at the time of maturity.

Grain yield components:

Grain yield components such as panicle weight, panicle number, spikelets per panicle

were presented in tables 6.2.11, 6.2.12 and 6.2.14. The experimental mean of panicle weight

was 125 g, with 270 panicles/m2 and each panicle consisted approximately 173 spikelets.

Sampada and Varadan (130) among the varieties are superior to other three test entries that

have positively responded to treatment. An average improvement of 10 panicles/m2 and 10

grains/panicle as a result of treatments was recorded across the locations irrespective of non –

significant interaction. Thus, an increase of 100 grains/m2 due to treatment was evidenced

and extrapolating this to an additional grain yield response of 10 Kg with silicon could be

obtained. In that, both treatments were equally effective. Location wise, MTU and PNR were

found to be benefitted more by silicon application which is statistically significant.

Grain yield and its components

Grain yield and its components such as filled grain number ( Table 6.2. 13) 1000

grain weight (g), grain yield and harvest index ( HI) (Tables 6.2.15-6.2.17) were found to be

superior under the treatments at RWA and TTB locations. As a result of silicon application

unfilled spikelets reduced and slight improvement in 1000 grain weight obtained. The grain

weight increase was significant at RWA and TTB locations with a marginal influence

brought under silicon treatment.

Grain yield improvement as a result of silicon solubilzers was found to be significant

at RWA and TTB. There was a differential response with respect to grain yields obtained due


6.39

to silicate and carrier molecule application. Also, the response of genotypes was not uniform

across the locations. AS high as 70g/m2 grain yield increase in Sampada was recorded to as

low as 28 g/m2 in Nagarjuna variety while in hybrid, PHB 71 it was 100g/m2 to as low as 35

g/m2 in KRH-2. The enhanced grain yield differences did not change the % HI significantly

in any of the test locations perhaps due to the better partitioning ability achieved by the

silicon fertilizer treatment as evidenced by the close proximity of TDM at maturity amongst

the various genotypes. Thus, the results of silicon seems to be mediated through better

partitioning ability and the varieties seems to be catching up with the hybrids at later stages of

growth responses mediated through the better partitioning ability of the silicon treatment.

These preliminary results establish that silicon indeed seems to be beneficial to rice crop. Table 6.2.1 Influence of Silica on Phenology at different AICRIP Centres Kh 2012

6.3. Evaluation of rice genotypes for Heat tolerance to high temperature.

Locations : DRR, PNR, FZB, MTU, TTB, REWA and PTB

Carbon dioxide and other green house gases (GHGs) are collecting in the atmosphere trapping the sun's heat and increasing the global temperature. Although local temperatures fluctuate naturally, over the past 50 years the average global temperature has increased at the fastest rate in recorded history. At the present rate of emissions, average temperatures could be 3 to 9 degrees higher by the end of the century. Rice is highly susceptible to heat stress, particularly during the reproductive and ripening stages. Extremely high temperatures, even for a few hours, during flowering can cause complete sterility, while high temperatures during ripening can lead to reduced grain filling and poor milling quality (i.e. more broken grains). And, in combination with other constraints such as lack of water, canopy temperatures can increase even further.

A coordinated trail was initiated at different AICRIP centres to investigate the influence of post-anthesis heat stress on yield and related components and to identify genotypes which could be used as donors and imparting high temperature tolerance. A total of 22 entries were comprising of 9 AVT-2 ME2011 entries, 5 released varieties and 8 popular hybrids (APPENDIX) were included in the trail. Heat stress was imposed in the field immediately after panicle initiation stage by enclosing the field grown crop with a make shift locally fabricated polythene tent, duly supported by iron rods and wooden sticks. The polythene cover was removed at the time of harvest and the data on yield and other attributes were recorded. Temperatures were recorded both inside and outside the polythene tent.

DRR

At DRR, Hyderabad enclosing the field grown crops polythene tent had resulted in a significant increase in both maximum temperature and a modest in minimum temperatures inside the tent (Fig. 1).

Fig. 1: Maximum and Minimum temperatures recorded inside and outside the polythene tent at DRR, Hyderabad during grain filling stage.


6.57

Field grown crop was enclosed in the polythene immediately after the PI stage. No significant differences in days to flowering were noticed between stressed and control plants as the crop experienced similar thermal regimes up to PI stage. However, significant differences were noticed among the test entries (Table 6.3.1). Similarly no differences were observed in days to maturity between stressed and control treatments. Heat stress had resulted in significant reduction in number of panicles per sq.m. The differences among the entries was also found to significant. The panicle number between 257 (DRRH-3) and 683 (N-22) with a mean of 343 under ambient temperature and under elevated temperature the number of panicles ranged from a minimum of 250 (PA 6129) to a maximum of 697(N-22) with a mean value of 330 (Table 6.3.2). Elevated temperature during the reproductive growth had resulted in significant reduction (22% reduction over ambient control) in total dry matter recorded after harvest. Significant variation was noticed amongst the tested entries. The interaction between the treatment and varieties was also found to be significant. The TDM varied between 1733 g m-2 (N-22) and 1264(PB-71) with a mean of 1417 g m-2 under ambient temperature and it ranged between 1539 (N-22) and 926 (Lalat) with a mean of 109 g m-2 under elevated temperature. The reduction was higher in PA-6201 (46%) followed by PA-6129, Lalat, IET 21415 and US-382 (>30% reduction over ambient control). The reduction in TDM was marginal (<15%) in DRRH-3 (1.9%), IET-22116 (3.1%), N-22(11.2%) and KRH-2 (14.4% ) (Table 6.3.2). Similarly, elevated temperature had significantly reduced (42% reduction over ambient temperature) the grain yield (g m-2) in all the tested entries. However, significant variation was noticed among the entries in their response to elevated temperature. The reduction in grain yield by elevated temperature was >50% in entries like PA-6201, Lalat, KRH-2, PA-6129, IET-21582, PHB-71, US-382 and US-312. On the other hand the reduction in grain yield was <5% in IET-22116 (1% reduction) in N-22(3% reduction with respect to ambient controls). It is to be noted that the entry N-22 is already confirmed as heat tolerant genotype and is subjected to detailed physiological and molecular studies worldwide (Table 6.3.3).


6.58

Fig.2 : Influence of elevated temperature on grain yield of different rice varieties.

Elevated temperature had resulted in significant increase (65% over ambient) in the mean unfilled grains per panicle for all the tested entries. Significant differences were observed in the response of different entries to the elevated temperature. The increase in unfilled grains was very high in LALAT, PA-6201, IET-21404, KRH-2, PA-6129, MTU-1010 and IR-64. Similarly the increase in the unfilled grains was very less in entries like US-382, IET-2216, N-22 and IET-21411. High temperature during grain filling had significantly reduced the 1000 grain weight. The reduction in the mean 1000 grain weight is 10.3% with respect to ambient temperature control plants. Significant variation was observed amongst the entries and the interaction between the temperature regimes and the entries was also found to be significant (Table 6.3.3). The test weight was reduced in all AVT2-ME entries, hybrids and varieties (Fig. 3). The reduction was lowest in N-22 which is a known heat tolerant varieties.


6.59

Fig. 3 : Influence of elevated temperature on 1000 g weight in rice genotypes, at DRR.

A significant reduction (36% with respect to ambient temperature) in number of filled grains was observed in plants grown under elevated temperature. Significant variation was noticed in the response of tested varieties to elevated temperature. The reduction is more pronounced in entries like PA-6201, KRH-2, Lalat, PHB-71, IET-21582, US-382, US-312 and PA-6129. Entries like IET-22116, IET-22218, IET-21411, IET-21415 and N-22 the reduction in filled grains is relatively low (<10% with respect to ambient control (Table 6.3.2). Remobilization of carbon and other mobile nutrients from the stem and leaf sheath of cereal crops is very important source of grain filling. However, the contribution of remobilized carbon increases under abiotic stress conditions like drought and high temperature. Influence of elevated temperature on dry matter remobilization was studied by comparing the stem dry weights collected at flowering and at the harvest. Exposure to high temperature had stimulated the remobilization of carbon from the stems to the developing grains. The stimulation was observed in all the entries. However, significant differences were noticed in the remobilization efficiency. Amongst the AVT2-ME cultures, the remobilization was lower under ambient temperatures in IET-21415, IET-21404, IET-21582 and IET-21411. Stimulation of remobilization was very high in IET-21415, IET-21411 and IET-22218.


6.60

Fig. 4: Influence of elevated temperature on dry matter remobilization and remobilization

efficiency (%) in different rice genotypes

Significant variation was noticed among the hybrids in the remobilization efficiency both under ambient and elevated temperature conditions. Remobilization efficiency was lower in PA-6201, PA-6444 and PA6129. No stimulation in remobilization was observed in these hybrids. The stimulation in remobilization efficiency was higher in KRH-2, DRRH-3 and PHB-71. Remobilization was not increased by high temperature in US-382 and US-312. Remobilization efficiency was lower in IR-64, Lalat and MTU-1010 among the popular varieties included in the study under ambient conditions. Exposure to high temperature had not resulted in stimulation of remobilization in Lalat and MTU-1010. Remobilization efficiency was higher in PR-113 under both control and elevated temperature conditions. The stimulation in remobilization was high in IR-64 (Fig. 4).


6.61

Based on the effect of high temperature on grain yield IET-221116 and IET-22218 can be identified as relatively tolerant to high temperature. The reduction in grain yield in these genotypes is marginally less than the confirmed heat tolerant variety N-22. Both these AVT2ME2011 entries exhibited higher remobilization efficiency, though not the highest remobilization efficiency. FZB

At Fizabad no significant difference were noticed between ambient and elevated temperature grown plants in days to flowering as the field grown crop was exposed to high temperature only after the PI stage. Similarly, no change in days to maturity was observed between the two treatments. Exposure to elevated temperature had resulted in moderate reduction (7% reduction with respect to ambient control) in mean number of filled grains per panicle. Variation amongst the tested entries were observed. The reduction in filled grains was highest (>10% reduction) in IET-21404 and PA-6444 and in all other entries the reduction is <10% (Table 6.3.6). Exposure to elevated temperature had resulted in 17% increase in mean number of unfilled grains per panicle for all tested entries. Significant variation was noticed among the entries. The increase in number of unfilled grains varied from 54.5% (KRH-2) to 7.5% (IET-22100). IET-22116 and IET-2218 are the other AVT2-ME 2012 entries in which the increase in unfilled grains per panicle is <10%. (Table 6.3.7). Exposure to elevated temperature had not resulted in a significant reduction total dry matter recorded at harvest. The interaction between entries and temperature was also found to be non-significant. Similarly no significant differences were observed in mean 1000 grain weight between the ambient and elevated temperature grown plants (Table 6.3.8). Less than 5% reduction in the grain yield recorded at harvest in plants grown under elevated temperature at Fizabad. In none of the tested entries the reduction in grain yield was more than 5% with respect to the ambient control except KRH-2 and IET-22100 in which the reduction was 6% . MTU

At Maruteru centre the temperature inside and outside the polythene tent was recorded. The mean temperature inside the tent during the grain filling phase was 33.8°C where as the mean temperature outside the tunnel was 30.1°C (Fig. 5). No differences were observed in case of days to flowering and days to maturity at MTU centre. Table 6.3.4 Elevated temperature inside the polythene tent had no significant influence on the number of panicles / m2. However, marginal differences were noticed between the entries included in this trial. In MTU-2010, IET-22116 and IET 21411 higher temperature inside the polythene tent had resulted in >15% reduction in No. of panicles/m2, where as higher temperature had a positive effect on No. of panicles in PR-113, Lalat, US-382, IET-21577 and IET-21404 (>15% increase over ambient control) (Table 6.3.5). Influence of elevated temperature on spikelet sterility was measured in terms of number of filled and unfilled grains in the panicle. Elevated temperature had significantly (30% over ambient temperature) increased the mean number of unfilled grains for all the entries. The increase in unfilled grains varied between 137 (IET-21411) to 0.46% (IET -21477). PA-6129, US-382 and IET-21404 are the other


6.62

entries wherein the increase in No. of unfilled grains/Panicle is >50%. The increase is marginal (<5%) in Lalat, MTU-1010 and PR-113 (Table 6.3.5).

Fig.5 : Temperatures recorded outside and inside the polythene tent at Maruteru centre during the grain filling phase A significant reduction in No. of filled grains/panicle was observed under elevated temperature. The mean No. of filled grains for all entries under elevated temperature was 17% less in comparison with the mean no. of filled grains recorded under ambient temperature out side the polythene tent. The reduction in filled grains varied between 24% (PR-113) to 5.6% (PA-6444). IET-21411, IET-21582, IET-21515, N-22 and IET-2216 are the other entries in which the reduction in grain number per panicle is <5%. In entries like IET-21415 and IET-22100 the reduction in filled grain number per panicle is >15%. Similarly, a significant increase in number of unfilled grains was observed in plants grown under elevated temperature. The increase in mean number of unfilled grains for all the entries was 36.6%. Among the tested varieties the increase in unfilled grain No. varied from 0.5% (IET -21577) to a maximum of 137 (IET-21411). PA-6129, US-312, IET-21404 and US-382 are the other entries in which the increase in un-filled grain number was >50% Likewise, the increase in unfilled grain number was very less (<10%) in entries like PR-113, Lalat, MTU-1010, IET-22116 and PA-6444 (Table 6.3.6). Exposure to high temperature resulted in significant inhibition in total dry matter. The reduction in the mean dry matter recorded at harvest for all the entries is 14% in comparison with the plants grown at ambient temperature. Significant variation was noticed amongst the entries in their response to high temperature. The reduction in TDM varied between 33.7 (IET-21582) to 4% (IR-64). The reduction in TDM was >20% in US-312, IET-21411, PHB-71, IET-21577 and IET-22100. The reduction was <10% in US-382, DRRH-3, PA-6201, IET-22218, PR-113 and Lalat. Elevated temperature had adversely affected the grain yield in all entries included in this study. The reduction in mean grain yield under


6.63

elevated temperature. High temperature reduced the mean grain yield by 26%. Significant differences were noticed among the test entries in their response to high temperature. The reduction varied between 58% (DRRH-3) to 5.6% (PA-6444). IET-21577, MTU-1010 and IR-64 are the other entries in which the reduction in grain yield in comparison to ambient temperature is <10%. The reduction is >35% in KRH-2, PA-6201, IET-21515, PHB-71 and IET-21582 (Table 6.3.6).

Fig. 6: Influence of elevated temperature

Remobilized dry matter (carbon+nitrogen) is an important source for grain filling especially under stress conditions. The dry matter remobilization and remobilization efficiency was lower in some AVT2 ME entries i.e. IET-22116, 21415, and IET-22218 under ambient temperature. Elevated temperature had significantly increased remobilization in all AVT2ME entries except IET-22218 where no such stimulation was noticed. In case popular varieties under control treatments the remobilization was very low in N-22 and Lalat. High temperature stimulated remobilization all the entries but in N-22 , Lalat and IR-64 the remobilization efficiency was very high. Likewise in case hybrids included in this study, KRH-2 and PA-6444 remobilization was very low under control treatment. However, substantial increase in remobilisation was noticed in all entries by elevated temperature with the exception of PA-6444 where the a reduction in remobilization was observed (Fig. 6). At MTU under moderate high temperatures , PA-6444 IET-21577, MTU-1010 and IR-64 exhibited relative tolerance as the reduction in grain yield is <10% in comparison to


6.64

ambient temperatures. Surprisingly, the reduction in these varieties was less than the check variety N-22 at these centre. PNR

At Pantnagar centre significant increase in temperature was recorded inside the polyhene tent which was constructed after the PI stage. The mean maximum temperature during the grain filling period inside the polythene tent was 41.7°C where as the mean ambient temperature (out side the tent) was only 31.2°C. However, the mean minimum temperature was only 1.5°C higher inside the polythene tent.

during 2012 Kharif.

A marginal increase (7days) in mean days to flowering was noticed at PNR centre. However, no differences were observed in days to maturity (Table 6.3.10) as the crop matured in same period under both the temperature regimes. The postponement of flowering had not resulted in increase in maturity period resulting in shortening of grain filling period under elevated temperature. Exposure to elevated temperature had marginally reduced (3% reduction with respect to ambient control) the number of panicles/m2 . Significant varietal differences were noticed among the entries tested. In entries like IET-22218, PA-6201, PA-6129 and PHB-71 the reduction in No. of panicles/m2 was <15%, where as in KRH-2, IET-21415, DRRH-3, IET-21582, PA-6444 and MTU-1010 elevated temperature had a positive influence on increasing the No. of panicles/m2. In the remaining entries no effect of elevated temperature had been discernible (Table 6.310). Exposure to higher temperature inside the polythene tent had significantly reduced the total dry matter. The reduction in mean TDM (g/m2) for all the entries under elevated temperature was 39%. Significant differences between different entries in their response to higher temperature during reproductive phase was noticed. The reduction varied from 63% (PR-113) to 4% (MTU 1010). DRRH-3, N-22, IET-21582 and IET-22100 are the other entries in which the reduction in TDM was >50%. The reduction was <15% in PA-6201, IET-21515 and PA-6129 (Table 6.3.11). High temperature exposure resulted in significant reduction (36% with respect to ambient treatment) in the number of panicles at PNR centre. The reduction varied from 88% (KRH-2) to 9% (IET-22100). The reduction is >50% in PA-6201, PA-6444, PHB-71, IR-64, Lalat and DRRH-03. The reduction in number of filled


6.65

grains was >10% in MTU0110, PR-113, IET-21415 and IET-21577. Elevated temperatures caused very significant increase in the number of unfilled grains per panicle in all genotypes tested in this trial (Table 6.3.12). The increase is many folds in case of IR-64, DRRH-3, PA-6201 and N-22. Surprisingly, the increase in unfilled grains was comparatively less in PR-113, IET-21515, IET-22100 and KRH-2. Elevated temperature had resulted in substantial reduction (39% over ambient control) in grain yield recorded at harvest. The reduction varied between 66.5% (PA-6201) to 15% (IET-21577). The reduction in grain yield under elevated temperature was <25% in IET-21404, IET-21415 and IET-21411. However, the reduction in grain yield >50% in DRRH-3, US-312, KRH-2 and PHB-71 and PA-6129. Based on the yield response to high temperature IET-21577 and IET-21411 are relatively tolerant to elevated temperatures. These cultures show higher tolerance to temp. than the traditional check variety N-22 . PTB

At Pattambi centre covering the field grown crop with polythene had resulted in substantial increase temperature. The mean maximum temperature recorded inside the polythene tent was 42°C where as the mean maximum temperature outside the tent was only 32.2°C. The differences in the mean minimum temperature recorded inside and out-side the polythene tent was 6°C (Fig.8).

Fig.8: Mininum and Maximum temperatures recorded at PTB centre during Kharif-2012 No differences in mean 50% days to flowering was observed. However, the mean days to maturity for all the entries was reduced from 134 days under ambient temperature to 126 days under elevated temperatures which resulted in 7 days reduction in grain filling period (Table 6.3.13). Elevated temperature had resulted in significant reduction in the mean TDM recorded at harvest. The reduction in TDM varied from 62% (PR-113) to 1.7% (DRRH-3). PA-6201, US-312 and US-382 are the other entries in which the reduction is >50%. On the other hand in entries like IET-21515 and PHB-71 the reduction in TDM is <10% ( Table 6.3.14). Exposure to high temperature during grain filling period had resulted in significant reduction in the number of filled grains per panicle in all the verieties. Significant interaction between the treatment and varieties have been noticed. The reduction in number of filled grains varied between 84% (IET-22116) to 3% (IET-21411). The reduction was >50% in IET-21515, US-312, PA-6201 and IET-21577. However, the reduction in filled grain number


6.66

was <20% in PHB-71, IET-22100, PA-6129 and N-22. A significant increase in unfilled grain number per panicle was observed under elevated temperature. The interaction between the treatments and varieties was also found to be significant. Highest increase in number of unfilled grains was recorded in Lalat followed by IET-21582, PR-113, IET-22100, IET-21575 and MTU-1010. The increase in unfilled grains per panicle was moderate in IR-64, IET-21404 and PA-6201. High temperature during grain filling significantly reduced the grain yield in all the genotypes included in this study. Significant variation was noticed among the entries in their response to the elevated temperature. The reduction in grain yield varied between 91% (PA-6444) to 3.2% ( IET-22116). IET-21582, MTU-1010 and N-22 are the other entries in which the reduction in grain yield under elevated temperature was <10%. (Table 6.3.14) Based on the yield data IET-22116, IET-21582 and MTU-1010 can be identified as relatively tolerant varieties to high temperature. They performed relatively better than the check variety N-22. REWA

At Rewa centre the mean maximum temperature recorded inside the polythene tent was 42.7 C and the mean ambient temperature is 31.2 C. However, the differences between the ambient minimum temperature and minimum temperature recorded inside the polythene tent was only < 2C (Fig. 9).

Fig. 9 : Min. and Max. temperatures recorded during grain filling stage at Rewa centre.

At Rewa centre no significant differences were noticed between heat stressed and ambient temperature grown plants in days to flowering and days to maturity. No significant differences were noticed between the treatments in number of panicles per Sq.m (Table 6.3.15). Significant reduction was observed in number of filled grains per panicle under elevated temperature. The mean No. of filled grains/panicles for all entries was reduced by 29% under high temperature stress. The reduction in number of filled grains varied between 37.9% (DRRH-3 and PHB-71) to 3% (IET-21577). The reduction is <20% in Lalat and IET-21415. In the remaining entries the reduction varied between 20-32% (Table 6.3.15). A significant increase (90% increase over ambient control) in the mean number of unfilled grains per panicle was observed. The increase in unfilled grain number ranged from 32% (N-22) to 175% (IET-21577). IR-64 and US-382 are other entries in which the increase in unfilled grain number was <50% with respect to ambient control treatment (Table 6.3.15).


6.67

Relatively marginal reduction in total dry matter (g/m2) was noticed in the plants exposed to post-anthesis high temperature stress. The reduction in mean TDM for all the entries was 4%. The reduction varied from 10.9% (US-132) to 1.45%(IET-22218). However, no reduction in TDM under elevated temperature was noticed in Lalat, IET-21415 and IET-21411. Significant reduction in grain yield was observed in all the entries under elevated temperature . The reduction in mean grain yield was 33.4%. The reduction in grain yield varied between 47.5% (KRH-2) to 17.4% (IET-21582). The reduction in grain yield under elevated temperature was <25% in entries like N-22, PA-6201 and IET-21411 (Table 6.3.16) Exposure to high temperature (10°C higher) during reproductive stage resulted in differential response of tested entries. Based on yield reduction, IET-21582 can be identified as relatively tolerant to high temperature. Amongst the Hybrids, the reduction in grain yield under elevated temperature was lower in PA-6201 (<25%) than other tested hybrids. Similary, between the popular varieties N-22 followed by MTU-1010 the reduction in grain yield is relatively less. TTB

At Titabar centre exposure to high temperature during reproductive development had not significantly influenced the days to flowering or days to maturity. A marginal reduction (10% reduction with respect to ambient control) in mean number of panicles per sq.m was recorded in plants exposed to elevated temperature. The reduction in the number of panicle varied between 23% (DRRH-3 and IET-22218) and 3% (N-22 and PBH-71). Exposure to elevated temperature during grain filling stage had resulted in significant reduction (10% with respect to ambient control) in mean number of filled grains per panicle (Table 6.3.17). The reduction in number of filled grains varied between 37% (IET-21411) and 3% (PR-6129). The reduction is very low in IET-21404, IET-21411, IET-21415. A significant increase in the number of unfilled grains was observed in plants exposed to elevated temperature during reproductive grown. The increase in the mean unfilled grains was 23.9% . The increase in unfilled grains per panicle varied between a maximum of 68% (IET-22100) and minimum increase of 5.2% was observed in Lalat followed by PHB-71 and PA-6201. In IET-21577, IET-21515, IET-22116 and IET-22100 the increase in unfilled grains per panicle was >50%. A marginal reduction (6%) in 1000 grain weight was noticed in plants exposed to elevated temperature. The reduction in 1000 grain weight varied between 10.5% (IET-21411) and 0.7% (IET-22100). In the remaining entries the reduction in <5%. Exposure to high temperature during reproductive growth had reduced the mean grain yield for all the entries by 38% with respect to ambient temperature. The reduction in grain yield varied between 62% (IET -22100) and 14.2% (PR-113). The reduction in grain yield <50% US-312, IET-22218, IET-21515 and US-382 (Table 6.3.18 ). Amongst the AVT2-ME2011 entries IET-21515 was found to be relatively more tolerant where as US-382 and PR-113 are relatively more tolerant among hybrids and released varieties. All these varieties performed relatively better than N-22, the check variety included in this trial.

6.4. Screening of elite lines for drought tolerance in terms of sustenance period during dry spells (Rainfed Upland)

Locations: BHU, CTK, REWA, PTB, HAT

The cultivation of rice extends from drylands to wetlands and from the banks of the Amur River at 53° north latitude to central Argentina at 40° south latitude. Rice is also grown in cool climates at altitudes of over 2600 m above sea level in the mountains of Nepal, as well as in the hot deserts of Egypt. In India the upland rainfed rice is cultivated in 6 million ha of land comprising 3.5% of total rice area of the country. Drought is the most important constraint affecting the rice yield in upland rice cultivation. Drought tolerance characteristics of selected rice culture was being assessed at six AICRIP centres. During Kharif-2012 season a 72 rice cultures, consisting of 18 AVT-VE-DS, 6 AVT-2-E-TP, 7 AVT1-E-TP and 36 IVT-E-DS cultures (details are given Appendix) were gown under rain fed conditions to identify suitable cultivars. Important weather parameters like rainfall, minimum and maximum temperature etc. were recorded for each cooperating centre and using rainfall data, dry spells were identified. A dry spell was defined as 7 consecutive rainless days during the crop duration.

BHU

At BHU, Varanasi centre 54 IET cultures along with Anjali and Sahabhagidhan were included in the trial. Rainfall data from sowing to harvesting was collected and presented in Fig. 1. The crop received a total rain of 336.4 mm from sowing to maturity out of which 330 mm was received between sowing and flowering. During reproductive growth the crop received only 6.4 mm rain with a prolonged dry spell. However, during vegetative phase the rain fall distribution is very even with only one dry spell.

Fig.1: Distribution of rain fall at BHU during crop growth. Significant differences were observed amongst the 56 rice genotypes included in this study in days to flowering and maturity. The mean days to flowering and days to maturity for all the entries was 70 and 101 days, respectively. The days taken to reach 50% flowering varied between 57 (IET 23380) to 92 days(IET-22343). The days to maturity varied between


6.87

86 days(IET 23380) to IET-23343. The data pertaining the other important traits was presented in (Table 6.4.1). No significant differences in TDM recorded after harvest between the genotypes. However, the differences amongst the genotypes was found to be significant in case of grain yield. The grain yield varied from 133 g m-2 (IET 23350) to 711.7 (IET 23344) with a mean of 567.0 g m-2. IET-23354, IET-23341, IET- 23340 and IET-23344 are the other genotypes which produced yield >690 g m-2. These genotypes are more suitable under rainfed conditions as they performed well under prolonged dry spells especially during grain filling period (Table 6.4.2). PTB At Pattambi centre all the 72 entries were evaluated under rain fed condition. For better comparison of results a parallel irrigated treated treatment was also included. PTB centre received very high rainfall during the cropping season. The crop received 1441.6 mm rain from sowing to maturity period out of which 1253 mm was received between sowing and flowering and 188 mm between flowering and maturity. However, during reproductive stage, the crop experienced two dry spells of 11 and 6 days before the crop is harvested. Overall the crop received high rainfall with excellent distribution throughout the crop growing period (Fig. 2)

Fig.2 : Distribution of rain fall during the crop season at Pattambi centre (Kharif-2012)

At PTB the crop was grown under both irrigated and rainfed conditions. The data on yield and other important characters were analyzed as per split-plot design with water regimes as main plot treatment and genotypes as sub-plot treatment. Significant (P<0.05) differences were observed in number of tillers per plant between rain-fed and irrigated treatments. The interaction between treatment and genotype was found to be highly significant (P<0.01). The mean tiller number was reduced by 20% in rainfed condition. The differences among the genotypes was also highly significant (P<0.01). The tiller number per plant varied between a maximum of 29 (IET 23382) and a 5 (IET-22066) under irrigated condition with a mean of 9.94 and between 11.67(IET-22070) and 4.33 (IET-22347) with a mean value of 7.9 under rainfed condition (Table 6.4.3). The stem dry weight recorded before flowering is an important source of carbon during grain filling. The stem dry weight was significantly lower in rainfed crop. Significant variation was noticed in the stem dry


6.88

weight recorded at flowering among the tested genotypes. The interaction between treatment and genotypes was also found to be significant. The mean stem dry weight under irrigated condition was 18.5 g which was reduced to 8.9 g under rain fed condition. The stem weight under rainfed treatment varied between 16.7 g (Tulasi) to 4.56 g(IET-22743). IET-22373 and IET-22032 are the other two entries in which the stem dry at flowering was <5.0 g (Table 6.4.3). Under rainfed treatment, the panicle number per Sq.m was reduced in comparison to the irrigated treatment. However, the reduction is statistically not-significant. Significant (P<0.01) differences were observed among the genotypes. The number of panicles varied between 319 (IET-22078) and 77 (IET 23347) under rainfed condition. IET-22061 was another entry in which the number of panicles/m2 was >300. Significant reduction in number of filled grains per panicle (P<0.01) was observed under rainfed condition. The reduction in mean number of filled grains under rainfed condition was 22.7% with respect to irrigated control. The reduction was >50% in IET-21777, IET 22070, IET 23347, PA-6129 and IET-23384. In IET-23334, IET 23336, Anjali, IET-22020, IET-23339, IET-22061, IET-22743 and IET23330 the reduction in filled grain number under rainfed condition is <10% over irrigated control. However, filled grain number per panicle showed a positive response in entries like IET 23345, 23385, 23348, 23382, 23374, 22817, 22822,22081, 22763, 22767 and 22343. Similarly a significant increase in number of unfilled grains was observed. The differences among the genotypes and interaction between treatment and genotypes was also found to be significant (Table 6.4.4). The TDM(gm-2) was not significantly affected by the irrigation treatment. However, significant variation was observed between the genotypes. The mean grain yield recorded under rainfed condition was marginally higher than the irrigated control (7%), however, the increase is statistically non-significant. The grain yield varied between 595 g m-2 in (IET-22767) to 84 (IET-22348). IET-22061, IET-22761 and IET-23332 are the other genotypes which produced grain yield of >500 g m-2 under rainfed condition (Table 6.4.5).

Due to very high rainfall during the crop season at PTB, it is not possible to really identify suitable genotypes for rainfed situation as many genotypes produced higher yields under rainfed condition than the irrigated control. However, based on the grain yield all the above mentioned entries with >500 g m-2 grain yield can be identified as promising entries. REWA

At Rewa centre the crop was grown under rainfed as well as irrigated conditions. During the crop growth period the crop received a total of 1040 mm which is quite unusual for this location during kharif-2012. The crop suffered a prolonged dry spell of more than 12 days immediately after sowing and bearing two rainfall events (<40 mm ) the dry spell continued


6.89

Fig. 4: Distribution of rainfall during the crop growth period at Rewa centre during Kharif-2012. for almost 28 days after sowing. However the crop received continuous rain fall from 18th July up to 26th September with very good distribution of rain. Another dry spell occurred just before maturity which may not have any significant adverse effect. The crop received 761.4 mm rain from sowing to flowering and between flowering and maturity it received 279 mm of rain. The days to maturity differed between irrigated and rainfed treatment. The variation among the genotypes was also found to be significant. The days to maturity varied between 134 (IET 22341 and 23342) to 93 days (IET 23345). Significant differences were noticed in the days to flowring between the irrigated treatments. The mean days to flowering under rainfed treatment was 84 days where as under irrigated treatment the mean days to flowering was 87 days. The days to flowering varied between 102 (IET 22341 and 23342) and 72 day (IET 233345) under rain fed treatment (Table 6.4.6). Total dry matter was recorded after harvest and the differences in mean TDM between irrigated and rainfed treatment was found to be non-significant. However, significant (P<0.01) variation was noticed among the tested genotypes. Similarly, the interaction between treatment and genotypes was also found to highly significant (P<0.01). The TDM under rainfed treatment varied between 1125 g m-2 (IET-22020, 22586, 22747, 22824, 233339, 23342, 23343, 23349, PA-6129 and Sahabhagidhan) to 1716 g m-2 (IET-22091) (Table 6.4.8). Significant differences were observed between irrigated and rainfed treatments in case of number of tillers per plant. The tiller number of less under rainfed treatment. Significant variation exist between the genotypes and the interaction of treatment and genotype was found to be significant (P<0.01). The tiller number was highest under rain fed condition in IET -227752 where as IET-22373 recorded lowest number of tiller under rainfed treatment (Table 6.4.9). A marginal but significant (P<0.05) increase in number of unfilled grains was noticed under rainfed treatment. The increase in mean unfilled grain number is 12% under rainfed treatment with respect to irrigated treatment. The increase in number of unfilled grains was lowest (14.3) in IET-22083 and highest (40) in Tulasi. Significant reduction in grain yield was observed under rain fed condition. The reduction in grain yield is 36.6% under rainfed condition with respect to irrigated control. The reduction grain yield varied between 72% (IET 22083) to 4.1% (IET-22744). However, no reduction was observed in tulasi. In IET-23380, IET-22020,


6.90

IET 22020 and IET-23378 the reduction in grain yield under rainfed treatment was <10%. (Table 6.4.9)

Based on the yield measured after harvest under irrigated and rainfed conditions, important drought tolerance indices were computed. The drought susceptibility index (DSI) was calculated according to Fischer and Maurer (1978) as :

DYnsYsDSI /1−=

where Ys and Yns are yield under E2 and E1 respectively where D= Ynsm

Ysm−1

Ysm and Ynsm are mean yield of all genotypes under E2 and E1, respectively Yield stability ratio (YS) was calculated according to Lewis (1954) as:

YnsYsYS = x 100

where Ys and Yns are yield under E2 and E1 respectively and dry matter stress index (DMSI) was calculated as suggested by Islam et al. (1998) DMSI = (TDM under E2 / TDM under E1) x 100, where TDM is the total dry matter.

The mean DSI for all the genotypes was 1.0 indicating relative susceptibility of the genotypes to water stress. However, significant differences were noticed among the genotypes. The Drought Stress Index (DSI) varied between 2.0 (IET 22083) to a minimum value of 0.1 (IET 22744). The DSI >1.0 indicate drought susceptibility where as DSI<1 indicate relative tolerance. The DMSI varied between 109 to 67 among different varieties. Since the irrigation treatments had not significant effect on TDM, in the present trial DMSI is not a useful index for identification of drought tolerant genotypes. The yield stability (YS) was another useful trait for screening crop genotypes for drought tolerance. Based on the grain yield obtained from irrigated and rainfed treatments, the yield stability index (YS) was calculated. YS >50% indicate relative drought tolerance. Significant variation among the genotypes was noticed . The YS was very high in IET-22744 (>95) where as the YS was lowest in IET -22083 (<27) Table 6.4.7).

Based on the grain yield and other drought stress indexes, the entries IET-22744, IET-

23376, IET-22020, IET-23380 and IET-23381 could be identified as relatively drought tolerant genotypes. All these genotypes performed better than the check variety Sahabhagidhan. CRRI (CTK)

At CRRI the trial was conducted with all the 72 genotypes with irrigated control and rainfed treatments. Under the rainfed treatment the crop received 869 mm rain from sowing to maturity out of which 824 mm was received between sowing and flowering. The crop

Fig. 10: Rain fall distribution during the crop growth period at CRRI, CTK received on 45 mm rain during the grain filling period. The rainfall distribution is fairly uniform during the vegetative phase bearing a long dry period of 21 days. Another dry spell of <15 days was noticed at the fag-end of grain filling period. At CTK no significant differences were observed in case of days to flowering and days to maturity between irrigated and rainfed treatments. Plant height was reduced significantly under rainfed condition. The reduction in mean plant height for all the varieties was 10% under rainfed condition. Significant variation was observed between genotypes and the interaction between genotypes and treatments was found to be significant. The reduction in plant height varied between 26.5% (IET-23331) to 1.3% (IET-22817). IET-23384, IET-23373 are the other genotypes with <2% reduction in plant height (Table 6.4.10). The total dry matter was recorded after harvest. Irrigation regimes have no significant effect on the TDM. However, significant variation was observed between the genotypes for TDM. Similarly, the interaction between treatment and genotypes was also found to be significant. The TDM recorded under rainfed treatment varied between a maximum of 1047 g m-2 (IET-22057) and the TDM was lowest (321 g m-2 ) in IET-22020. Significant reduction (68% reduction) in mean grain yield for all varieties was observed under rainfed treatment. The reduction in grain yield varied between 8.44% (IET 23377) and 90.6 % (IET-22753). The reduction in grain yield was <15% in IET-23381, IET-22032 and IET-23377 indicating relative tolerance in these genotypes. The DSI was computed using the grain yield data obtained under rainfed and irrigated conditions. The DSI varied between 0.12 (IET-23377) to 1.33(IET 22733). DSI value <1.0 indicate relative tolerance of genotype. The YS (Yield stability ratio) was also computed and based on grain yield and other yield based indexes IET 23377, IET-23381, IET-22032 and IET-23377 can be identified as relative drought tolerant genotypes suitable for rainfed conditions (Table 6.4.12). HAT

At Hathwara cenre the crop received high rainfall of 1212 mm. The crop received 784 mm rain between sowing and flowering (vegetative phase) and 428 mm between flowering and maturity. The distribution of rain fall is very uniform and the crop never received any prolonged dry spells except a brief break (7 days) in rain before flowering and at


6.92

the fag-end of grain filling period a dry spell of 11 days was observed before maturity. No irrigation treatment could be imposed at this centre.

The mean days to flowering and maturity for all the genotypes were 70 and 100 days respectively. Significant variation was noticed in both days to floweing and days to maturity amongst the genotypes. The days to flowering varied between 56 days (IET- 22032) and 82 days (IET-22764). Similarly, the days to maturity varied between 87 (IET 23380) and 113 days ( IET-22764). Significant differences were observed amongst the genotypes for TDM recorded at harvest. The TDM varied between a maximum of 1360 g m-2 (IET -3331) and minimum of 412.3 (IET-22057). The differences among the genotypes for grain yield was found to be significant. The grain yield varied between 359 g m-2 (IET-23345) and 75 g m-2 (IET -22020) with a men of 219 g m-2. IET-22747, Sahabahagidhan, IET-22753, IET-23331, IET-23357, IET-22070, IET-253358 and IET 22767 are other genotypes which produced higher yield under rainfed condition and promising genotypes for rainfed cultivation (Table 6.4.13).

6.5. Submergence tolerance in rice Phosphorus management in relation to Submergence tolerance.

Locations: Cuttack and Titabar

In more than 16 million hectares rice is being grown under semi deep and deep water ecologies in world over. In India, Eastern and North Eastern region face flooding during seedling stage which will effect growth and yield substantially in Kharif Rice. FR13A is identified as a known source for Submergence tolerance and can with stand complete Submergence up to two weeks and survive in lowland areas. A major QTL designed as Submergence 1 (Sub-1) is identified and introgressed through molecular breeding into mega varieties which are widely grown such as swarna,IR-64 and samba Mashuri etc which are conferred with Submergence tolerance in these cultivars. These cultivars with Sub-1 gene offer tolerance to Submergence and can withstand standing water and yield better in semi and deep water ecologies. In the present study the influence of different phosphorus concentrations (20, 40, 60 and 80 kg/ha) on Submergence tolerance is investigated at two locations namely Cuttack (Orissa) and Titabar (Assam) in SwarnaSub-1, IR-64 Sub-1, CR1009 sub-1 and savitri sub-1 to understand the role of phosphorus in enhancing Submergence tolerance in the mega cultivars with sub-1 gene on growth, yield and yield attributes.

CRRI (Cuttack):

At CRRI Cuttack three cultivars [Swarna (Sub-1), IR-64 (Sub-1), CR1009 (sub-1)] with sub-1 gene were taken up for the study during Kharif-2012 under four levels of phosphorus @20,40,60 and 80 kg/ha. These cultivars were subjected to 14 days submergence and the data was recorded for growth and yield attributes along the control. The data is presented (Table-6.5. 1 to Table-6.5.8) and salient findings are discussed. Survival percentage was 100 percentages in control for all the three cultivars, under submergence the experimental mean values increased with increasing phosphorus concentrations. However the values are non-significant. Plant height decreased in all the three cultivars after submergence as compare to control grown plants and there was no significant difference for the effect of phosphorus levels on plant height under submergence. Panicle number per meter square was also non-significant under increasing phosphorus levels. Panicle weight, harvest index and spikelet fertility and straw weight had no-significant effect under different phosphorus levels under submergence. As for as yield is concerned there was a marginal increase in yield under increasing phosphorus levels. Among the cultivars CR1009 sub-1 was better in control and under submergence Swarna sub-1 had a better yield advantage which was significant among the three cultivars.

Titabar (Assam):

The same experiment was repeated at Titabar with the following sub-1 cultivars IR-64, Savitri and Swarna. At titabar survival percentage, plant height, panicle number per meter

square, spikelet fertility, straw weight and yield were measured in control and submergence tolerance (14 days submergence) under four levels of phosphorus (Table-6.5.9 to6.5.14) survival percentage and plant height did not shown any effect with different phosphorus levels. However panicle number and spikelet fertility was more at 40 kg/ha. Yield and biomass under submergence was highest at 40kg/ha. Phosphorus levels under submergence had no significant effect on yield and biomass. Among the cultivars IR-64 sub-1 had better yield and biomass which was significant.

Based on the study at two locations 40 kg/ha of phosphorus was found to be optimum under submergence conditions. At CRRI Swarna sub-1 and at Titabar IR-64 sub-1 were found to be superior in terms of growth yield and yield attributes at 40 kg phosphorus per hectare under submergence conditions.
