Infestations of Russian wheat aphid (RWA), Diruaphis noxia (Mordvilko), reduce grain yield and quality of barley, and have induced producers in some areas to cease growing barley (Hordeum vulgare L.). No RWA-resistant barley cultivars that are adapted to North America exist. Resistance from the germplasm line STARS 9301B was transferred into adapted germplasm via backcrossing. Our objective was to determine the potential utility of this resistance for the protection of yield and malting quality in adapted germplasm. We studied the effect of RWA infestations on grain yield and malting quality of STARS 9301B, the susceptible adapted parents 88Y315 and ‘Garnet’, and five backcross-derived progeny. Four of the backcross-derived lines were rated as highly resistant and one as moderately resistant, and were superior to STARS 9301B and similar to their recurrent parents with respect to agronomic performances and, to a lesser extent, malting qualities. When infested at the boot to heading stage, STARS 9301B, and the highly resistant progeny lines had negligible reductions in agronomic performances and malting qualities; slightly greater reductions were observed for the susceptible parents and the moderately resistant progeny line. When infested at the three- to six-leaf stage, STARS 9301B and the resistant backcross-derived lines showed relatively small reductions in their agronomic performances and malting qualities. In sharp contrast, however, the susceptible parents, and to a lesser extent the moderately resistant progeny line, showed moderate to severe leaf streaking and rolling, head trapping, and reductions in their agronomic performances and malting qualities. STARS 9301B should provide a valuable source of resistance to RWA damage.
