Abstract

An isolate (CA-RPV-1) of barley yellow dwarf virus (BYDV) recovered from barley (Hordeum vulgare) in Davis, CA, was transmitted to oats (Avena sativa) in a nonspecific manner by New York (NY) clones of Rhopalosiphum padi, Sitobion avenae, and Schizaphis graminum and by a California (CA) clone of Sitobion avenae. The oat plants showed characteristic BYDV symptoms. In double-antibody-sandwich and indirect monoclonal antibody ELISA, CA-RPV-1 reacted strongly to antisera made to NY-RPV and in some tests to a lesser degree to antisera made to NY-PAV or NY-MAV. Nonspecific transmission was found in 26% of the CA-RPV field isolates tested
