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.

 

Phenotype data

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

2. Facultative/Winter 2-row panel. 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. Grown 2016 crop only.

Phenotype, Genotype and QTL data

1. Multi-rust resistance Cycle I doubled haploid panel. 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. Grown 2016 and 2017. Integrates and leverages the stripe rust and stem rust NACAs.
2. Multi-rust resistance Cycle II doubled haploid panel. 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. Grown 2018. Integrates and leverages the stripe rust and stem rust NACAs.
