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.

The following hyperlinks will take you to reports and publications on various areas of endeavor related to barley stripe rust. To access the data underlying the reports, please send a request*  for access to the Box folder containing a treasure trove of phenotype and genotype data. Dr. Xianming Chen (USDA-ARS) conducts essential and comprehensive stripe rust assessments on a range of germplasm, including some of the experiments described on this page. The data from his endeavors are available at this site.
