Interpretive Summary: Stripe rust of barley is a serious disease that causes significant economic damage to barley grown in many areas of the world, including the Pacific Northwest region of the United States. Genetic resistance--the type that is a natural characteristic of a plant--is the most attractive way to fight this disease, because it comes at no cost to the producer and does not have the environmental hazards of chemical fungicides. We have produced a line, 95SR316A, that can be used as a parent in the production of stripe rust resistant cultivars for use in malting and brewing. No stripe rust cultivars that have been approved for malting and brewing in the United States currently exist, and barley breeder's use of parents that combine both stripe rust resistance and good malting qualities--such as 95SR316A--will eventually lead to the production of such cultivars.
Technical Abstract: 95SR316A is a two-rowed barley (Hordeum vulgare L.) germplasm line developed and released in 2007 by the Agricultural Research Service, U.S. Department of Agriculture. 95SR316A has favorable values for most agronomic and malt quality characteristics, and it is resistant to many races of barley stripe rust (Puccinia striiformis Westend. f. sp. hordei Eriks.). 95SR316A has the pedigree 'Bancroft'/'Crystal'. Both parents were developed by the USDA-ARS in Aberdeen, ID. Crystal (Wesenberg et al., 1991) has good agronomic characteristics and was approved by the American Malting Barley Association (AMBA) for malting and brewing from 1990 through 2001. Bancroft (Wesenberg et al., 2001) combined favorable agronomic and malt quality characteristics with resistance to most races of barley stripe rust, but did not receive recommendation as a malt barley from AMBA. Bancroft has been reported to have non-race speficic high-temperature, adult-plant (HTAP) resistance, which has proven to be durable (Chen and Moor 2003). The genetics of resistance in Bancroft have not been fully described, but recent work (X. M. Chen, ARS-Pullman, WA, personal communication) has indicated the presence of a major QTL associated with high-temperature adult plant resistance.
