From 1983 to 1986, 14,000 samples of cereal germplasm from domestic and foreign sources were screened for resistance to barley yellow dwarf virus (BYDV) in the field using the hill plot technique. Selected germplasm was inoculated with the GPV, GAV, and PAGV variants of BYDV by Schizaphis graminum (Rondani), Sitobion avenae (Fabricius), and Rhopalosiphum padi (L.), respectively. Zhong 4, a cross of two Chinese wheats (Triticum aestivumum L.), Ke Qiang and Nan Da 2419, with Thinopyrum intermedium (Host), and the barley cultivars Post, Atlas 68, and Sutter were good sources of resistance to BYDV. Zhong 4 showed mild symptoms and contained a low concentration of virus shown by enzyme-linked immunosorbent assay.
