These researchers are mapping genes in wheat, intermediate wheatgrass, and field pennycress that control important traits, including disease resistance, seed quality, and morphological traits. Segregated populations of 100-200 lines, Association Mapping panels, and breeding lines for genomic selection are phenotyped in appropriate environments, and populated with several hundred to several thousand DNA markers to identify DNA markers associated with genes or QTLs affecting the trait or develop genomic selection models. Genotyping-by-sequencing is being used to quickly build linkage map and identify linkages with causal genes. MSI resources used include mapping and genotyping software and storage space for data.
This research was featured on the MSI website in June 2016: Identifying Rust Resistance Genes in Wheat.
