连续5年(1996～2000年)采集晋南冬麦区小麦黄矮病标样,采用生物学和血清学(酶联免疫吸附法)相结合的诊断方法对该地区的大麦黄矮病毒流行株系进行了鉴别。结果表明,该小麦黄矮病流行区近五年以GAV株系为主流株系,兼有少量GPV、PAV和混合株系存在。同时对小麦抗黄矮病新品种“临抗1号”进行了GPV和GAV两种株系的抗性测定,明确了该品种兼抗GPV和GAV两种株系。根据小麦黄矮病发生现状,提出了一套以选育推广抗耐病品种为主,以药剂防治为辅的综合防治措施。以期为当地小麦生产服务。
The samples of yellow dwarf virus from winter wheat in Jinnan were collected for five years in a row (1996 ~ 2000). The prevalence of barley yellow dwarf virus in the area was determined by a combination of biological and serological methods (enzyme-linked immunosorbent assay) Department has been identified. The results showed that the prevalence of yellow dwarf virus in the past five years with GAV strains as the mainstream strains, both a small amount of GPV, PAV and mixed strains exist. At the same time, the new resistance variety “Linkang 1” with resistance to barley yellow dwarf was tested for its resistance to GPV and GAV, and the two strains of GPV and GAV were identified. According to the status quo of wheat yellow dwarf disease, a set of comprehensive prevention and control measures with the promotion of resistance to disease-resistant varieties as the mainstay, supplemented with the prevention and treatment of pesticides was put forward. With a view to serving local wheat production.
