Identification and Purification of a Principal Strain of Wheat Yellow Dwarf Virus(BYDV)
Abstract: The principal strain of BYDV, as certified, is the Schizaphis graminum et Rhopalosiphum padi strain which is widely distributed at the northern mid-harvest, late harvest winter wheat and spring wheat growing areas in China. While it was specifically transmitted by the prominent vector inset Schizaphis graminum,several areawide prevalence and damage accidents have occurred during the previous years. We have purified the samples of GPV strain, and improved and simplified the procedure of purification.
