GEM- Ames 2014 Highlights (Dr. Candice Gardner)
Midwest Germplasm releases and development:
Two hundred sixty-nine (269) GEM releases are now available to GEM Cooperators.
Ten GEM lines from the Ames program are proposed for release to GEM Cooperators for the
2015 planting year (Table 1). Yield data, and NIR results for protein, oil, and starch can be
found online and in the handout for 2015 released lines. Pedigree, race, percent exotic,
heterotic background, agronomic characteristics, and NIR information are presented in Tables
1-3. Six of the ten releases are second cycle GEM lines from GEMN-0097, -0140, -0155,
and from GEMS-0147, -0175, and -0180. Their parent lines derive from races that were
collected at one time from Argentina, the British Virgin Islands, Brazil, Guatemala and
Thailand. The remaining new releases derive from Brazilian and Thai germplasm. All new
codes have respectable scores for Fusarium ear mold and for grain quality.

2014 Research & Breeding Activities
A second year trial of 400 top crosses of BC1S2 generation families of CUBA164xB73) x B73
and CUBA164xPHB47) x PHB47 were planted in yield trials at four locations at low,
medium, and high population densities, collaborative research with Dr. Jode Edwards. This
research is designed to provide a better understanding of the effects of exotic alleles from
CUBA164, particularly for response to high plant density, and is part of an MS thesis study.
Eighty eight new breeding crosses were made in the Ames nursery. GEM Cooperators made
15 additional breeding crosses as part of their in kind support.
Twelve new breeding cross populations were assigned to Cooperators for in kind support.
Twelve families of single seed descent (SSD) balanced bulks were advanced to S2 in Ames,
and two were advanced by Cooperators.
Twenty-two populations of BC1’s were sibbed in Puerto Rico in January 2013 as a result of
TSG member support. The BC1-sib1 generation was returned to Ames and random mated a
second generation in 2013 to generate the BC1-sib2. Four family sets of the random mated
populations (BC1-sib1 and BC1-sib2 and the original BC1’s were induced in 2014 in Ames to
generate haploids, as well as advanced conventionally. This study was designed to compare
the frequency of exotic alleles in doubled haploid lines developed directly from the BC1 vs.
from BC1’s random mated for one or two generations, and similarly from conventionally
derived lines. Families induced in summer 2014 include Cuba 164, Amargo-ARZM 03 014,
Tusón-CUB 67, and Tusón-BAI III, all with the PHB47 recurrent parent.
Ph.D. student Adam Vanous' research objectives are to utilize 1) selection mapping to dissect
the genetic architecture of adaptation from the tropics to the U.S. Corn Belt (mass selected
populations), and 2) association mapping to dissect the genetic architecture of flowering time
and photoperiod response in exotic derived DH lines. Three tropical landraces, Tusón
4
(Hallauer, 1999), Tuxpeño (Hallauer, 1994), and Suwan-1, are the sources of exotic
germplasm that have undergone pre-breeding and were adapted to the Midwest Corn Belt
through recurrent mass selection on the basis of early female flowering. Two hundred-fifty-
two BC1F1 derived doubled haploids (DH) lines represent the backcross method of
introgression. Current and novel mapping techniques will be used to indentify loci associated
with early flowering time in maize.
Host Plant Resistance:
2014 disease data will be posted online at our website (http://www.public.iastate.edu/~usda-
gem/) in January. Pathology and entomology research collaborators from the private and public
sectors screened GEM lines, top crosses, and breeding crosses for Northern Leaf Blight (NLB),
Southern Leaf Blight (SLB), Goss’s Wilt, Gray Leafspot (GLS), Diplodia ear rot (DIPPER),
Aspergillus (aflatoxin and other mycotoxins), Corn ear worm (CEW), Fall Armyworm (FAW),
and Western corn root worm (WCR). Please see the quality traits sections regarding ear mold and
mycotoxin studies.
A wet spring and excessive rain events followed by the dry summer impacted data collection and
resulted in some missing plots, but less so than in recent years. Appreciation is extended for the
in-kind support and extensive efforts by private and public GEM Cooperators:
CAAS (Chinese Academy of Agricultural Science) provided agronomic evaluations and
disease ratings for various leaf blights including MRDV, Fusarium ear mold, and for common
smut.
DuPont/Pioneer Hi-Bred International (Bill Dolezal at Johnston, IA, and Mark Mancl at
Woodland, CA) .NLB or DIPPER data were collected at Johnston and Fusarium ear rot and
Head Smut were successfully evaluated at Woodland, CA,.
Professional Seed Research (Jim Dodd) for their efforts collecting data on Goss’Wilt,
Eyespot, GLS, NLB, and SLB.
3rd
Millennium Genetics (Ed and Raechel Baumgartner) for tropical insect evaluations on
GEM lines in Puerto Rico which was particularly helpful to identify some material for Fall
Armyworm (see Table following public cooperator reports).
USDA-ARS-CGBRU (Xinzhi Ni) in Tifton, GA collected data for Corn ear worm (CEW),
and Fall Armyworm.
USDA-ARS-PSRU in Raleigh, NC provided data for SLB (Peter Balint-Kurti) and Fusarium
ear rot (Jim Holland).
USDA-ARS-PGRU, Columbia, MO (Bruce Hibbard) evaluated corn rootworm (CRW)
USDA-ARS-CHPRRU, Mississippi State, MS (Paul Williams and Gary Windham) evaluated
aflatoxin in grain.
Second year host plant resistance evaluation data (2014) will be posted to our website under
“GEM Germplasm Releases and Key Traits”. Unfortunately, there has not been time to review
1st and 2
nd year data together at the time of this report. Appended to the end of this document are
tables from P. Williams on evaluations of germplasm for aflatoxin, and from E. and R.
Baumgartner for fall armyworm evaluation trials.
Ames 2014 Allelic Diversity (AD) and Double Haploids (DH):
The Iowa State University Doubled Haploid Facility continues to partner with the GEM
Project on development of DH lines. Approximately 204 lines (representing ~52 races) were
jointly released by ISU and USDA-ARS in 2014 as part of the Allelic Diversity Project. The
DH lines provide unique genetic resources for a wide variety of maize research applications.
Twenty sets of the doubled haploid released lines were distributed to requestors, and a subset
of lines to those who wished to narrowly targeted their requests. Another seed increase was
made of the 204 DH lines this summer, and phenotypic information was collected in Ames.
5
Approximately 237 new DH lines (DH0) were advanced to DH1 in 2014. This was part of
Andrew Smelser’s thesis research to study the rate of induction and doubling with exotic
germplasm from the allelic diversity project.
Self pollinations were made in 580 rows ranging from BC1F5 to BC1F6 allelic diversity
project germplasm to generate the BC1F6 to BC1F7 generations. This effort is part of the GEM
allelic diversity project but information will be used in various thesis research projects
Ames 2014 Yield Test, Nursery and Other Highlights:
Approximately 15,370 plots (2,530 entries) were managed or coordinated through Ames in
2014 (increase of more than 50% over 2013).
Among these, 470 entries (18.6%) were in 2nd year and 2,060 entries were in 1st year trials.
Two hundred and two (202) top crosses out of 2,530 entries exceeded the mean yield of the
check hybrids in Midwest trials in 2014. Of the 202 hybrids that exceeded the mean, 142
were from first year trials, and 60 from second year trials.
Approximately 7,460 nursery rows for pollination, over 300 for observation, and 1,880
isolation rows were managed by Ames.
One hundred new breeding crosses were observed and evaluated for breeding potential in
Ames, IA, Ft. Branch, IN (AgReliant), and Memphis, TN (G&S Crop Services). Of these
100, 44 had above average scores at all three locations; 28 scored >6.0 on a 1-9 scale and will
be considered for development.
Quality Traits (including grain mold/mycotoxin):
The newly released GEM lines were not noteworthy for protein, oil or starch traits.
An unreleased line, AR17056:S1217-B-001-B showed segregation in the next generation of
harvested ears for a waxy trait. This line was not sufficiently high performing to release, but
is available to interested cooperators.
Aflatoxin analyses show six breeding crosses with very low, promising levels of aflatoxin
(Appendix Table 1). The report by Paul Williams and Gary Windham will be available
online.
Three newly released lines were evaluated favorably for Fusarium ear mold.
New GEM Cooperators in 2014:
One new private U.S. Cooperator joined the GEM Project in 2014; Summit Genetics (in
cooperation with KMR) conducted yield trials in Stanton and Takama, Nebraska.
New international cooperators include Global Investors, LLLP, of Des Moines, IA with their
partner companies Misr Hytech (Cairo, Egypt) and Hytech Seed India Pvt. Ltd.
(Hyderabad, India). These international cooperators have already provided valuable
information on GEM germplasm resistant to late wilt in their respective environments,
and will continue to screen germplasm for late wilt, southern rust, and other diseases as
opportunities are presented.

Germplasm development:
Overall 2500 GEM nursery plots and 700 GEM isolation plots were grown in Clayton,
NC, with additional GEM-related nursery managed by Major Goodman.
S1 families were developed from nine breeding crosses: 89291:(LH51), 89291:(LH59),
BR51039:N15, BR51039:S15, BR51675:D27S21, BVIR155:S20, GEMN-0097/GEM-
0104, NS1:(GEMN-0097), and NS1:(GEMS-0115).
Families from eight GEM breeding crosses were advanced from S1 to S2: BR106:(GEMN-
0097), BR106:N42, BR106:S42, BR51501:N11a, BR51501:S11a, BR51721:S20,
GUAT209:N19, PASCO14:S11.
Eighteen GEM x GEM F1 combinations were produced based on yield trial data.
Approximately 140 new breeding crosses were developed between tropical hybrids
(ATL100, SX1078 and SX2788 from Brazil) or tropical inbreds (89291 from IITA-
Cameroon; CML277, CML313, CML339, CML340, CML343, CML395, CML423,
CML438, CML494 and La Posta Sequia C7 F71-1-1-1-2-B*3 from CIMMYT and
CA34502 and CA00370 from CIMMYT-Asia; N3-2-3-3 from Zimbabwe) and GEM-
Ames releases (GEMN-0048, GEMN-0097, GEMS-0113, GEMN-0158, GEMS-0175,
GEMS-0200, GEMS-0220) and ex-PVPs (AS5707, DKF118, DKMM402A, LH195,
LH197, LH210, NK787, NKW8555, NS701 and PHN46). Both groups were selected
based on performance in yield trials.
Germplasm Evaluation in 2014:
7
Overall, 11,700 yield plots were coordinated from Raleigh, with 7300 planted in NC and the
rest planted by seven cooperators at various locations throughout the Southeast and
Midwest.
Thirty-three entries were evaluated at eighteen locations in third-year trials (EXR1 and
EXS8; see Yield Trials section)
Fifty entries were evaluated in second-year trials, approximately twenty of which will be
evaluated in third-year trials in 2015.
162 entries were evaluated in first-year trials, fifty-eight of which will be evaluated in
second-year trials in 2015.
Evaluations of GEM releases from Raleigh and Ames were conducted in two experiments
(EXP8 and EXP9) for the third year to identify lines with the best potential for use in GEM
x GEM crosses. EXP8 (releases from Raleigh) was planted at locations in the southern Corn
Belt and southeast, while EXP9 (releases from Ames) was planted in North Carolina and the
Corn Belt. A subset of the best performing GEM lines from the 2010 and 2011 trials (EX26-
EX29) were planted in the 2014 trials along with more recent releases. Ex-PVPs were
included in both trials for comparisons with GEM releases (see Yield Trials section).
Breeding crosses were evaluated per se in the Raleigh nursery (see Breeding Crosses
section).
Ex-PVP inbreds were evaluated by Major Goodman at five locations in North Carolina and
results for three trials conducted over three years (EXA2), two years (EXF1) or one year
(EX60) will be available on the GEM website and in this booklet in Yield Trials section.
Allelic Diversity:
There were 300 summer nursery rows dedicated to the development of F1s and BC1s for the
Allelic Diversity project, and 310 rows were planted in Homestead, FL for the 2014 winter
nursery. Much of the effort in the winter nursery is focused on late maturing accessions.
Twenty-two BC1 families and two F1s were completed this summer in Raleigh; two BC1
families and fifty-two F1s were also completed in the 2013 winter nursery.
Other GEM-Raleigh recommendations:
Based on 2013 and 2014 nursery observations, some of the most promising new breeding
crosses include GEMN-0097 x GEM-0104, GEMN-0097 x CML449, GEMN-0097 x
CML375, GEMS-0027 x GEMS-0113, GEMN-0135 x GEMN-0104, and GEMN-0124 x
GEMN-0043.
Some of the best entries in EXP8 were GEMN-0043, GEMN-0119, GEMN-0207,
GEMN-0208, and GEMN-0212. Efforts are already underway to recycle most of these
GEM releases and efforts in recycling will continue in 2015 with an emphasis on non-
Stiff stalk GEM releases (recycling of Stiff Stalk releases was emphasized in the 2014
nursery).
Some of the best entries from EXP9 were GEMS-0091, GEMN-0097, GEMS-0113,
GEMN-0158, and GEMS-0175. GEMN-0097 had the highest value for Y/M, while
GEMS-0050 had the highest yield of any GEM entry but also had the highest moisture of
any entry in the trial. Efforts are underway to recycle these and other GEM releases from
Ames.
Some of the most promising ex-PVPs based on yield trial data are DKF118, DK6F629
and DKMM402A from EXA2 and DKNL001, LH197, LH198, LH204 and PHKE6 from
EXF1; however, it should be noted that, as a line per se, LH198 performed very poorly in
both the summer and winter 2014 nurseries and LH197 was marginally better.

GEM TSG Meeting, September 15-16, 2014, Ames IA - Highlights:
The GEM Technical Steering Group (TSG) meeting was held at the North Central Regional Plant
Introduction Station in Ames, IA on September 15-16, 2014. A tour of the nurseries was hosted by
Candice Gardner, Fred Engstrom, Michael Peters and Nuo (Mack) Shen. Graduate student Adam Vanous
participated and discussed his research. The tour included inbreds, all generations of breeding material in
the nursery, observations of Raleigh and Ames materials and the released doubled haploid lines, new
potential breeding crosses, Ex-PVP lines, and some topcross trials at the nearby Uthe Farm. Several
important topics included:
program focus and balance between new research initiatives on breeding methodology vs.
traditional germplasm development; relative focus on four program areas
requesting new tropical germplasm sources, especially from company cooperators
strategies for sampling of adventitious presence (AP) of transgenes, appropriate points to test, and
how to deal with it if found.
alternative strategies for supporting GEM programs
improving maize doubled haploid systems, inducibility and spontaneous doubling
potential collaborations with international organizations and entities for evaluating important
diseases and their races, and the challenges involved
methods to measure GEM Project success and/or impact
proposal by D. Butruille to expand GEM’s YT program in Ames
improving GEM’s technical capacity at Raleigh and Ames.

FIELD DAYS:
Ames, IA GEM Project (C. Gardner) GEM Project 2014 Field Day:
Due to severe damage to the demo field from heavy spring rains, lost population stands and lack of available
fertilizer, no public field day was held in 2014. The TSG members toured the nursery plantings and one
yield test location in mid-September, and numerous local and international visitors scheduled tours of the
nursery as their interests dictated.
Caitlin Ellingson, an undergraduate GEM employee, created a virtual tour that documents the growth and
development of the GEM field demo over 11 weeks of the season. She developed a web based presentation
of this as part of her journalism internship; it can be accessed at http://ncrpis-
gem.agron.iastate.edu/virtualtours.asp .
Fargo, ND North Dakota State University (M. Carena) 2014 Nursery Tours:
Over 500 US and international visitors toured summer breeding nurseries with new NDSU EarlyGEM lines,
hybrids, and population releases; short-season NDSU EarlyGEM releases were specifically shown. Three of
the past 2014 inbred releases were from the NDSU EarlyGEM program as well as the last 10 populations
releases included breeding crosses with germplasm originating in southern USA, Mexico, Cuba, St. Croix,
Brazil, Chile, and Argentina
Beijing, China, Chinese Academy of Agricultural Sciences (CAAS) 2014 Field Days:
Aug 29 to Sep 6: The third international GEM Field Day was sponsored by CAAS and hosted by Dr.
Tianyu Wang, coordinator of China’s GEM Program. More than 70 attendees from the public and
private section participated in this event and observed 987 elite local inbred lines and three
breeding enhancement populations, as well as 196 GEM populations and selfed progenies at the
Shunyi Research Station in Beijing. Breeders and scientists provided feedback on germplasm they
wish to work with.
PUBLIC COOPERATOR REPORTS (Specific Cooperative Agreements, or SCAs): The GEM Project funded two SCA’s in 2014, Dr. Jay-lin Jane, Iowa State University, and Dr. Mark
Campbell, Truman State University; their reports can be found below. A third SCA was initiated late in the
fiscal year with Dr. Thomas Lübberstedt of Iowa State University, and the project is in the early stages.

Project Title: Development of GEM line starch to improve nutritional value and biofuel production
Prepared by Hanyu Yangcheng and Jay-lin Jane, Department of Food Science and Human
Nutrition, Iowa State University, Ames, IA 50011
Project Overview
This report serves to document research conducted under a cooperative agreement between ARS and
Iowa State University. Specific objectives of this research project are to (1) Develop and characterize
hybrids using normal and waxy GEM lines to produce hybrids with improved yield and starch-ethanol
conversion efficiency to increase ethanol yield; and (2) Develop healthy foods and healthy food
ingredients using GEM lines.
For Objective 1, a normal (B73) and a waxy (08GEMS05044) inbred corn and two hybrids developed by
intercrossing between the normal and waxy corn were used in this study. Amylose contents (3.9-26.5%)
of the starch negatively correlated with the dosage of the wx gene in the corn endosperm. Average
amylopectin branch-chain lengths (DP 18.4-19.9), however, showed no correlation with the wx gene
dosage. The amylose content of the starch was inversely proportional to the gelatinization enthalpy-
change (12.0-14.5 J/g), the gelatinization temperature-range (Tc-To) (10.2-11.7 °C), and the raw-starch
digestibility (r = -1, p<0.001), but positively correlated with the percentage retrogradation (38.2-64.9%)
and starch pasting-temperature (69.6-75.7 °C) (r = 1, p<0.001). These results indicated that amylose
molecules enhanced the integrity of starch granules, restricted granule hydration, narrowed gelatinization
temperature-ranges, and reduced digestive-rates of the starch. Amylose contents, instead of the
amylopectin branch-chain length distribution, showed dominant effects on starch physicochemical
properties. Starch of the hybrid, 08GEMS05044×B73, displayed significantly lower amylose content and
higher digestibility than the normal corn starch. The hybrid showed potential to improve the yield of
ethanol production.
To further investigate the dosage effects of wx gene on starch physicochemical properties, an intercross
study using two pairs of isogenic lines grown in 2014 was conducted. Starch gelatinization enthalpy
change was positively related with the dosage of wx gene in the endosperm. Final and setback viscosities
of the starch decreased with increase of the wx gene dosage, whereas breakdown viscosities increased
with increases of the wx gene dosage. Following work will be conducted to understand if the wx gene
has dosage effects on starch molecular structures and digestibility.
For Objective 2, the hybrid popcorn (GEM-07048) produced by crossing a popcorn (Sg1533) with a
high-amylose corn (GEMS-0067) was used in this study. The corn kernels of GEM-07048 were
separated visually to two groups, normal popcorn with an amylose content of 36.3% and high-amylose
popcorn with an amylose content of 61.4%. The high-amylose popcorn displayed the smallest expansion
volume (11.8 cm/g) compared with the normal popcorn seeds (19.7 cm/g) and commercial popcorn (34.9
cm/g). The popped kernels of high-amylose popcorn showed largest resistant starch content (46.3%),
indicating its potential as a healthy snack food.

Characterization of starch from intercrossed normal and waxy maize
Two hybrids were developed by intercrossing between a normal (B73) and a waxy corn
(08GEM05044). Dosages of the wx gene in endosperms of the inbred and hybrid corn are: 0 (B73),
1(B73×08GEMS05044), 2 (08GEMS05044×B73), and 3 (08GEMS05044) (Table 1). Starches of the corn
lines were isolated using a wet-milling process, and the isolated starch was used for the study to understand
the starch physicochemical properties and to reveal the effects of amylose contents and amylopectin
structures on starch properties and digestibility.
Amylose content of the starch ranged from 3.9 to 26.5%, and was negatively related with the
wx gene dosage in the endosperm (Table 1). Amylopectin molecular weight ranged from 1.4 to 1.7×109
(g/mol), and showed a trend of positive correlation with the wx gene dosage in the endosperm.

Results of amylopectin branch-chain length distribution are shown in Table 2. Average branch-
chain length of amylopectin ranged from DP 18.4 to 19.9, and showed no correlation with the wx gene
dosage.
Starch thermal properties are shown in Table 3. Starch onset-gelatinization temperatures (62.3-65.4
ºC) negatively correlated (r=-1, p<0.001) with the percentage of short branch-chains of amylopectin (30.1-
34.5%) (Table 2). Gelatinization enthalpy change (12.0-14.5 J/g) negatively correlated (r=-1, p<0.001) with
the amylose content (Table 1), whereas percentage retrogradation of gelatinized starch (38.2-64.9%)
positively correlated (r=1, p<0.001) with the amylose content. The amylose molecules complexing with
lipids and interacting with amylopectin to preserve integrity of the starch granule and restrict granule
swelling contributed to the smaller gelatinization enthalpy change and higher percentage retrogradation of
the starch.

Starch of the hybrid (08GEMS05044×B73) displayed significantly lower amylose content
(21.0%) and higher digestibility (87.2% at 120min) than the normal corn starch (26.5% and 79.6%
at 120min, respectively), indicating its potential to improve the yield of ethanol production.
To further investigate the dosage effects of wx gene on starch physicochemical
properties, an intercross study using isogenic normal and waxy GEM lines was conducted. Two
pairs of isogenic lines were grown in 2014, including waxy1 (wx1) and normal1 (N1) and waxy2
(wx2) and normal2 (N2). The pedigree information of these four lines and their F1 progeny
obtained through reciprocal crossing is shown in Table 6.

Starch thermal properties are shown in Table 7. Starch gelatinization enthalpy changes
increased with increase of the wx gene dosage in the endosperm. Onset gelatinization temperatures
showed no correlation with the wx gene dosage. The conclusion temperatures, however, showed a

Future work will be conducted to understand if the wx gene has dosage effects on
the starch content, content of amylose, molecular size of amylose and amylopectin, branch-
chain length of amylopectin, and starch digestibility. Relationships between the physical
properties and the structures of the starches will be investigated.
Kernel popping properties and starch digestibility of high-amylose popcorn
GEM-07048 (Pedigree: (GEMS-0067/Sg1533-B)-B) was produced by intercrossing
between a popcorn line (Sg1533) and a high-amylose corn (GEMS-0067). Kernels of GEM-07048
were visually separated to two groups, high-amylose popcorn (HAPC) and normal popcorn (NPC).
Kernel starch content, starch amylose content, and expansion volume of popped kernels are
shown in Table 9. The HAPC of GEM-07048 showed a significantly greater amylose-content
(61.4%) than the NPC of GEM-07048 (36.3%).

The expansion volume of GEM-07048 kernels was smaller than commercial popcorn (34.9
cm/g). The expansion volume of HAPC of GEM-07048 (11.8 cm/g) was even lower than that of the
NPC kernels (19.7 cm/g). The amylose content was negatively correlated with the expansion
volume (r = 0.862, p < 0.05).
Starch digestibility of popcorn kernels after microwave popping is shown in Table
10. The popped kernels of HAPC showed largest resistant starch content (46.3%) and slowly-
digestible starch content (19.3%) than the other two popcorn samples. The amylose content (Table
9) was positively correlated with resistant starch content and negatively correlated with rapidly-
digestible starch content.

These results indicated that high-amylose popcorn is a good source of resistant
starch and slowly-digestible starch, which is potentially a healthy snack food. Further efforts,
however, are needed to improve the popping characteristics of high-amylose popcorn.

2014 GEM Report: Truman State University, Annual GEM Cooperator meeting, ASTA, Dec. 10, Chicago, IL
Development and Evaluation of Specialty Starch Germplasm Utilizing GEM Biodiversity to Optimize Grain Quality, Composition, and Yield. Duration 2011 – 2015
Mark Campbell, Cynthia Cooper, Amanda McClure and Linsa Dean, Sushma, Shrestha and Adrianne Alexander General Objectives: Truman state has served as a public cooperator in GEM program in order for student to activity participate in demonstrating the economic value of exotic maize germplasm, educates students, the local, state and scientific community of the necessity to support the National Plant Germplasm System. Our work consist of developing parent lines and hybrids with altered starches that address current trends in industry and concerns of consumer and health specialists. Our source of used at Truman for line development relies exclusively on materials released by GEM cooperators. In addition, DH lines recently released from the allelic diversity study are being introgressed into our existing genetic materials which expands the diversity used to develop and improve novel specialty starch maize. Additionally, we have used landraces adapted to specific areas where this material could potentially serve as an affordable source of prebiotic in areas vulnerable to gastrointestinal illnesses such as cholera. Specifically, our breeding efforts fall into two categories which are believed to address the following consumer needs (1). Developing high-amylose corn which has a number of niche applications, one of which includes its use as a source of resistant starch (RS) having prebiotic properties that have well documented health benefits and functional attributes making it well suited as a ‘nutraceutical’ dietary supplement (2). The second starch type involves developing sources of a slowly digested unmodified starch (SDS) from native genetic diversity. Rather than focusing on RS starch, the rate of starch hydrolysis and other components in the grain influencing retention which may determine its potential applications in controlling blood sugar. Although a number of applications exist, evaluation of our materials involved the glycemic-index (GI), glycemic load (GL), -Amylase Inhibitors and the recent observations made regarding interactions observed in human metabolomics http://www.hmdb.ca/metabolites/HMDB06857 and cereal carbohydrates. Our material may serve to assist in understanding strategies that best identify therapeutic food choices for diabetic and glycogen disorder patients suffering from nocturnal hypoglycemia. This past summer several ongoing studies and new approaches used in the development of germplasm has taken place. Highlighted are field studies that demonstrate agronomic potential of Amylomaize lines developed using only GEM parents under varied environmental conditions. Continued effort involving collaboration of Truman State with A.T. Still Medical College and ISU is being accomplished.
Hybrid Evaluation Evaluation of hybrids had previously been made from crosses between SS and NS lines believed to have alleles fixed resulting in starch amylose at or exceeding 70% during the 2009/10 winter nursery with good success and the results reported in the 2012 GEM report. A series of unfortunate events have made progress in this area challenging since then. From the earlier study, an additional crossing block was prepared using two of GEM amylomaize lines exhibiting good general combining together with a number of SS and NS intended for planting during the 2011/12 winter nursery in Puerto Rico (Table 1). This seed, however, was lost in transit, eventually recovered, and planted during the 2012/13 season instead. The seed was successfully planted; however, during flowering insect damage greatly limited the amount of successful crosses. Some of this material was planted
22
in Ames, IA during the summer of 2013. The results of this study are provided in Table 2. Due to the unfortunate loss of a fellow GEM private cooperator and friend, no winter crossing blocks have been made since. It will soon be necessary to identify an alternative plan, perhaps through in kind support of a GEM cooperator to ensure continued hybrid field experiments as new inbreds are developed. Table 1. Crossing block grown during the 2012/13 winter nursery and numbers of successful ears recovered following crossing are shown.

Results from the yield evaluation grown in Ames, IA in 2013 are provided in Table 2. Seed obtained from the 2012/13 crossing block (Table 1) was intended to be used as a source for hybrid entries which are indicated by the purple entry numbers in Table 2. The delayed arrival and extensive insect damage required that seed from 2009/10 was used (geen entry numbers) to complete the experiment. Entry 47 (AR03056:N09-24-1-B-B-B////DKXL370:N11a20-31-1-B-B-SIB///GEM67 X CUBA164:S2012-444-1-B///GEM67) displayed the greatest yield with a plot average of 156.0 bu/ac.
Of the entries from the later crossing block, entry 16 (BVIR155:S2012-029-001-B-B////UR10001:S1813-257-1///GEMS-67 x AR03056:N09-191-001-B-B-B-Sib/////AR03056:N09-182-1-B-B-B////CH05015:N15-3-1-B-B///GEMS-67) displayed the greatest yield at 153.2 bu/ac. In fact, a number of independent ears having similar parentage were used as independent entries due to the insect damage that resulted in a lack of successful crosses. This provides useful information regardless of the poor hybrid cross attempts since BVIR155:S2012-029-001-B-B////UR10001:S1813-257-1///GEMS-67 had not been used in any experimental hybrids in the past and suggests that lines derived from this pedigree be further prioritized for increasing yield performance. Table 3 was made to examine SS lines that had a common parent constituting 50% of their pedigree. The lines possessing 2088-01_DK212T_S11_F2S4_9157-Blk29/00-sib-B-B-B/////DKB844:S1601-73-1-B-B-B////AR16035:S02-615-1-B-B///GEMS-67 averaged the greatest yield of 147.0 bu/ac. In addition, lines with GUAT209:S1308a-120-001-B-B and BVIR155:S2012-029-001-B-B////UR10001:S1813-257-1///GEMS-67 consistently performed well. During the summer of 2014, an effort was made to include remaining seed of experimental hybrids that had not yet been examined. Stand counts suffered for many as a result of as a result of seed aging. Early planting if followed by cool damp conditions also make emergence of amylomaize stands suffer. There were a few hybrids that yielded fairly well. In some cases, seeding rates routinely used
24
may be excessive for amylomaize VII material and, therefore, yields may have increased with decrease seed viability. CHIS775:S1911b-120-1-B-B-B////AR16035:S02-615-1-B-B/// GEM67 X AR03056:N09-191-001-B-B-B-Sib/////AR03056:N09-182-1-B-B-B////CH05015:N15-3-1-B-B/// GEM67

Developing ears were inoculated with Aspergillus flavus using the side-needle technique 7 days after mid-silk.
Ears were hand harvested at maturity, dried, and shelled. Grain was ground and aflatoxin concentration was
determined using the Vicam Aflatest. Values for aflatoxin concentration were transformed [ln(y+1), where y =
aflatoxin concentration] prior to analysis of variance. Geometric means were calculated by converting the
transformed means to the original units of measure.
