Our research is aimed at (1) understanding the genetics of traits that will make barley profitable and sustainable in the Midwest and (2) applying that genetic understanding to develop improved varieties through breeding. Our breeding program develops spring-sown and fall-sown (winter) barley varieties. Our spring breeding program has been in place since the early 1920’s and has been focused on varieties suited to the malting and brewing industries. As such, the primary traits of interest our yield, malting quality traits, and disease resistance, in particular Fusarium head blight. Our winter breeding program started in 2009 and the major emphasis is to improve winter hardiness, yield, and malting quality. Introducing winter barley in Minnesota cropping systems could help increase crop diversity, improve ecosystem services such as improved soil conservation, nutrient cycling, and weed suppression in addition to increasing yield and facilitating earlier harvest.
To accomplish our breeding goals we are actively involved in implementing and evaluating a variety of breeding methodologies. We use genetic markers in our program including those that are identified through bi-parental QTL mapping and genome-wide association studies (GWAS). This has lead to the use of marker assisted selection (MAS) to select for desirable alleles as well as a genomic selection (GS) approach that uses genome-wide markers to make predictions about important traits that can be used in selection.
