Narrative
Six-rowed feed barley. In grain yield tests (10 trials) in the San Joaquin Valley, it averaged 6,804 kg/ha1, which was 9% more than `UC 933' and 12.4% more than `UC 937' . In the Sacramento Valley (10 trials), Ishi averaged 7,272 kg/ha, which was 5.5% more than UC 933 and 12.6% more than UC 937. In rainfed environments (12 trials), Ishi averaged 3,134 kg/ha, which was 91% of UC 933 and was similar to UC 937, indicating no advantage for It in low rainfall, dryland situations. Ishi has the sdw1 gene and is short statured, averaging 84.6 cm, and is similar to UC 937 and 3.6 cm taller than UC 933, averaged over 32 location-years in Central Valley and Central Coast environments. For lodging resistance it averaged 2.5 (4-14%) on a scale of 1 to 10 and was superior to UC 937 but similar to UC 933 over 20 environments where lodging occurred. For days to heading it averaged 4 days earlier than UC 937 and 3 days later than UC 933, but all three cultivars were similar for time to maturity. Times for heading and maturity were noted only at UC Davis (5 environments). Ishi is moderately resistant to Barley yellow dwarf virus, leaf rust (caused by Puccinia hordei Otth.), powdery mildew [caused by Erysiphe graminis DC. f. sp. hordei Esm. Marchal; syn. Blumeria graminis (DC.) E. O. Speer], net blotch (caused by Pyrenophora teres Drechs.) and scald [caused by Rhynchosporium secalis (Oudem.) J.J. Davis] . Ishi is resistant to pathotypes of stripe rust (caused by Puccinia striiformis Westend. f. sp. hordei) existing in the Central Valley of California as a result of the transmission of resistance from UC 960. It is heterogeneous for rough and smooth awns having less than one-percent smooth awned plants. The spike is waxy and semi-erect. Kernel weight averaged about 46.5 mg over 13 environments and was about one mg. more than that observed for UC 933 and about one mg. less than for UC 937. Test weights (31 location-years) for UC 1047 averaged 62.8 kg/hL and were not significantly different from those measured for UC 933 or UC 937. The kernels are covered and the aleurone is non-blue. Grains are long (>10mm), wrinkled, hairs on ventral furrow. Rachilla hairs are long.
