Interpretive Summary: This registration article describes the unique traits of eight newly released winter feed barley germplasm lines resistant to both Russian wheat aphid and greenbug. These are the first dual aphid resistant lines in barley. This will facilitate the use of these lines by barley breeders worldwide.

Technical Abstract: STARS 1006B (Reg. No. GP- , PI 659760), STARS 1007B (Reg. No. GP- , PI 659761), STARS 1008B (Reg. No. GP- , PI 659762), STARS 1009B (Reg. No. GP- , PI 659763), STARS 1010B (Reg. No. GP- , PI 659764), STARS 1011B (Reg. No. GP- , PI 659765), STARS 1012B (Reg. No. GP- , PI 659766), and STARS 1013B (Reg. No. GP- , PI 659767), are winter, six-rowed, feed 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,(Kurdjumov)], and greenbug [GB, Schizaphis graminum (Rondani)]. Each resistant line is in a 'Post 90' background and comparable to 'Post 90' in yield, test weight, heading date, and height in the absence of RWA and GB. Each line is highly resistant to both RWA and GB and has a wide area of adaptation ranging from irrigated production in the Northwestern US to dryland production in the Southern plains where both RWA and GB can be problematic.
