【摘要】 经测试结果,小麦黄矮病毒(BYDV)主流株系为麦二岔蚜禾谷缢蚜株系(GPV),普遍分布于我国北方中熟冬麦区、晚熟冬麦区和春麦区;以麦二岔蚜的传播能力最强。由麦二岔蚜优势介体所传播的主流株系GPV,曾导致该病多次大面积流行成灾。并对GPV株系毒源进行了提纯;对其提纯方法有所改进和简化。更多还原

【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.更多还原
