RI perspectives from crop group parallel sessions

Wheat State of the research by 2014 and

beyond

Wheat Projects in the RI Molecular breeding and selection strategies to combine and validate QTL for improving WUE and heat tolerance of wheat in India – Vinod Prabhu Molecular breeding and selection strategies to combine and validate QTL for improving WUE and heat tolerance of wheat in China – Ruilian Jing Generating new wheat germplasm with enhanced drought/heat tolerance using AB genome genetic diversity – Satish Misra Breeder friendly high-throughput phenotyping tools to select for wheat adaptive traits in drought environments – Fernanda Dreccer

Overall

• All projects have some activities that may need support beyond 2014

• In the wheat product catalogue one product deleted and several added (14)

• Sources for documentation identified and actions set against names to provide data to IBP

• Agreed that a more detailed costing of activities to be completed to be provided mid October to provide the basis of a plan going forward.

Molecular breeding and selection strategies to combine and validate QTL for improving WUE

and heat tolerance of wheat in India

Products forecast December 2014 Extensive phenotype on 145 lines evaluated at 4 locations for heat and drought QTLs for WUE identified in 4 MARS populations

Molecular breeding and selection strategies to combine and validate QTL for improving WUE

and heat tolerance of wheat in India

Activities beyond 2014 (or requiring additional resources) Sets of elite lines based on the released varieties HD2733; HD2967; GW322; GW366; PBW343 with pyramided QTLs for drought and heat tolerance from MABC (2016) Series of elite lines with accumulated with QTL for heat and drought coming from four MARS populations. DH derived lines from MABC from crosses of HD2967 with Babax, Excalibur and Krichauff

Molecular breeding and selection strategies to combine and validate QTL for improving WUE

and heat tolerance of wheat in China

Products forecast December 2014 A winter wheat cultivar released. Developed using MABC targeting QTL for stem water soluble carbohydrates and thousand kernel weight using 2 SSR markers (depending on 2013 results). Zongmai36 Extensive phenotype of 145 lines evaluated at 4 locations for heat and drought in China SSR markers for major QTL for plant height and drought tolerance in Chinese elite lines.

Breeder friendly high-throughput phenotyping tools to select for wheat adaptive traits in drought

environments

Products forecast December 2014 Novel large-scale phenotyping methodologies for drought adaptive traits in spring wheat based on a combination of methods (Crop reflectance; canopy temp and visual observations) A database for up to 245 genotypes of the phenotypic expression for ground cover (GC), canopy temperature (CT), carbon isotope discrimination (CID), soluble stem carbohydrates (SSC) and yield and agronomic traits

Breeder friendly high-throughput phenotyping tools to select for wheat adaptive traits in

drought environments

Activities beyond 2014 (or requiring additional resources) Method combining image capture and crop simulation modelling to estimate patterns of WU and Transpiration Efficiency throughout the growth cycle Environment characterization of key locations in India & China using historical weather records to estimate most probable in season stress occurrences (new activity)
