Research Project: Improving Barley and Wheat Germplasm for Changing Environments

Location: Plant Science Research

Project Number: 6645-22000-017-07
Project Type: Reimbursable

Start Date: Feb 28, 2011
End Date: Jan 31, 2015

Objective:
Extensively phenotype and genotype diverse and designed germplasm pools to mine and deploy alleles that improve barley and wheat adaptation and performance under biotic and abiotic stress, and couple these activities with the training of a new generation of plant breeders.

Approach:
Develop and implement large- and small-scale SNP genotyping platforms for barley and wheat breeding programs, and test novel sequence-based genotyping platforms. Integrate the genotypic and phenotypic information into GRIN, GrainGenes, and Gramene databases and develop web-based tools to help breeders use this information. We will develop 48 and 384 SNP platforms dedicated to known genes or previously identified marker-trait associations for barley and wheat. These SNP platforms will be available at the Small Grains Genotyping Centers for breeders to characterize breeding lines in advanced yield trials. Simultaneously, we will test new genotyping technologies based on high-throughput sequencing platforms (e.g. gene capture and sequence-based genotyping) in barley and wheat and implement them as they become economically feasible.
