N2  - The Yd2 gene confers resistance to barley yellow dwarf virus (BYDV). Isogenic lines Atlas 68 (+Yd2) and Atlas 57 (-Yd2) from California and two common barley cultivars from Mexico, Centinela and Cerro Prieto, were exposed to the following treatments: infection with a PAV-like BYDV isolate vectored by Rhopalosiphum padi (L.) at the three- to four-leaf stage; infection with the same isolate at flowering; spraying with systemic insecticides; and natural infection. Significant yield decreases were observed with all the barley cultivars except Atlas 68
