Interpretive Summary: This chapter describes the development of the winter feed barley 'Mesa' (Hordeum vulgare) with resistance to Russian wheat aphid.

Technical Abstract: Russian wheat aphid (RWA, Diuraphis noxia (Kurdjumov)) infestation is a serious constraint to winter barley (Hordeum vulgare) production in the western U.S. An Iranian landrace with RWA resistance was crossed to the adapted U.S. cultivar ‘Schuyler’ (Jensen, 1972), followed by multiple backcrosses. Resistant plants were selected in Oklahoma and evaluated in field trials in Colorado and Idaho. ‘Mesa’ was the superior line in those trials and was released for production in 2017 (Mornhinweg et al., 2017). Mesa, a 6-rowed winter habit feed barley, is classified as highly resistant to RWA and yields as well as its parent Schuyler, both in the presence and absence of RWA pressure.
