摘要

STARS 0637B (Reg. No. GP-189, PI 642923), STARS 0638B (Reg. No. GP-190, PI 642924), STARS 0639B (Reg. No. GP-191, PI 642925), STARS 0640B (Reg. No. GP-192, PI 642926), STARS 0641B (Reg. No. GP-193, PI 642927), STARS 0642B (Reg. No. GP-194, PI 642928), and STARS 0643B (Reg. No. GP-195, PI 642929), are spring, two-rowed barley (Hordeum vulgare L.) lines developed cooperatively by the USDA-ARS, in Stillwater, OK, and Aberdeen, ID, as sources of resistance to Russian wheat aphid (RWA) [Diuraphis noxia, (Mordvilko)]. Each resistant line is in one of three, two-rowed, feed barley cultivar backgrounds (‘Bowman’, ‘Hector’, or ‘Otis’). They are comparable to their recurrent parents in yield, test weight, plant height, and heading date in the absence of RWA and superior in grain yield to their recurrent parents in the presence of RWA.
