Since 1983 four isolates of barley yellow dwarf virus (BYDV) in China have been identified by a series of experiments involving comparative transmmission by four aphid species and enzyme-linked immunosorbent assay (ELISA) tests using antisera for MAV, PAV, RPV, and RMV, from the USA and the UK. These isolates are: GPV, transmitted nonspecifically by Schizaphis graminum (Rondani) and Rhopalosiphum padi (L.), a new isolate of BYDV that does not react to the antisera for MAV, PAV, RPV, or RMV; GAV, transmitted nonspecifically by S. graminum and Sitobion avenae (Fabricius), related to the MAV and PAV variantes; PAGV, transmitted nonspecifically by R. padi, R. maidis (Fitch) and S. avenae, similar to the PAV isolate; and RMV, transmitted specifically by R. maidis, very similar to the North American RMV isolate. S. graminum is the most important vector of BYDV in China.
