'Sidney' (Reg. No. CV-344, PI 641939), a Russian wheat aphid [RWA, Diuraphis noxia (Kurdjumov)]-resistant, spring, tworowed, feed barley (Hordeum vulgare L.) tested as 98BX 44B, was developed and released by the USDA-ARS, Stillwater, OK, and Aberdeen, ID; Colorado State University; and the University of Nebraska. Introduction of RWA to the United States effectively eliminated spring barley, the preferred alternate crop, in winter wheat (Triticum aestivum L.) rotations, in eastern Colorado and western Nebraska. 'Otis', a spring barley well adapted to the high dry plains, is susceptible to RWA. STARS 9301B, the first RWA-resistant barley germplasm line released in the United States, has a high level of resistance to the aphid. With RWA resistance from STARS 9301B transferred to Otis through backcross breeding, Sidney outperforms Otis in this marginal production area. Crop Science Society of America.
