Journal of Plant Registrations, Vol. 1, No. 2, September 2007 141 95SR316A (Reg. No. GP-180, PI 644104) 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 (PI 531249; Wesenberg et al., 1991) has good agronomic characteristics and was recommended by the American Malting Barley Association (AMBA) for malting and brewing from 1990 through 2001. Bancroft (PI 605474; 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 specifi c high-temperature, adult-plant (HTAP) resistance, which has proven to be durable (Chen and Moore, 2002). The genetics of resistance in Bancroft have not been fully described, but recent work (Yan and Chen, 2007) has indicated the presence of a major QTL associated with high-temperature adult plant resistance. 95SR316A is a spring, two-rowed, hulled barley with a semi-lax spike that remains upright at maturity. Awns are rough, rachilla hairs are long, glume hairs are banded, hulls are wrinkled, kernels have a transverse crease at the base, and the aleurone is white. 95SR316A originated as an F4:5 spike selection and tested as headrow #316A in 1995, and was entered into preliminary yield nurseries at Aberdeen and Tetonia, ID in 1996. The initial selection was based on visual observations for favorable plant and spike characteristics, and for resistance to barley stripe rust in Cochabamba, Bolivia. Subsequent selection was based on agronomic performance in replicated yield trials, and continued resistance to stripe rust in fi eld trials conducted from 1997 through 2004 in various locations: Toluca, Mexico; Huancayo Registration of 95SR316A Stripe Rust-Resistant Two-Rowed Barley Germplasm
