Resistance to barley stripe rust

Thanks to collaboration with the USDA-ARS (with funding provided by a NACA) we are working with colleagues at ARS, Aberdeen, ID; UC Davis, CA; and ARS-Pullman, WA to characterize levels of adult plant resistance to barley stripe rust, identify the QTLs/genes responsible for the resistance phenotype, and to deploy resistance alleles in new genetic backgrounds.

BSR screening trial (BSRST). Advanced lines/varieties and checks submitted by OSU (Hayes, Fisk, Helgerson, Hernandez); WSU (Brueggeman); UC Davis (Del Blanco); and ARS-ID (Hu, Evans). Grown annually.

BSR validation population. Selected BSR-resistant germplasm from Cycles I and II. Corvallis, OR and Davis, CA 2020

 

Cycle 0: A germplasm array of 139 doubled haploid advanced lines/varieties and 4 checks comprised of malting elite - preliminary yield trial entries from the OSU breeding program. 2016 crop year.

 

Cycle I: A germplasm array of 117 doubled haploid lines derived from crosses among parents with resistance to one or more rust diseases (stem, stripe, leaf) and 4 checks. 2016, 2017 crop years. Integrates and leverages the stripe rust and stem rust NACAs.

Cycle II : A germplasm array of 384 doubled haploid lines derived from crosses among parents with resistance to one or more rust diseases (stem, stripe, leaf) and 4 checks. 2018 crop year. Integrates and leverages the stripe rust and stem rust NACAs.

Cycle III: A germplasm array of 386 doubled haploid lines derived from crosses among parents with resistance to one or more rust diseases (stem, stripe, leaf) and checks. 2019 crop years. Integrates and leverages the stripe rust and stem rust NACAs.

Cycle IV :
