Research Interests
Our breeding research effort is allocated to white winter wheat. Breeding methods employed by the program include bulk, pedigree, single seed descent, and backcross, depending on the breeding objectives. A regional variety testing program is conducted annually.
Current Research Interests
Our research program utilizes appropriate technologies encompassing molecular genetics, physiology, pathology, and breeding to research strategies that contribute to the development of superior crop varieties. We collaborate with plant breeders and geneticists around the world including international centers on projects that involve the use of molecular markers to assess genetic relationship, construct linkage maps, and clone genes. The focus of our basic work involves comparative genomics, association mapping, allele characterization and particularly genomic selection methods. Current research projects include mapping, cloning and characterization of candidate genes underlying QTL for milling and baking quality, kernel size and shape, and nutritional quality.
