小麦黄矮病是由大麦黄矮病毒(BYDV)侵害引起的病毒性病害,它能为害大麦、小麦、莜麦、玉米、高粱、谷子等禾本科作物和多种杂草,影响结实率和籽粒饱满程度。据我们测定,小麦受病植株可减产56.2%,莜麦减产37.4%。近年来黄矮病在国内间歇流行为害,造成很大损失。1981年我们收集了内蒙古生产上已经推广应用的小麦品种83个,进行接种鉴定,选出一些比较抗病和耐病品种,可供生产上因地制宜地调剂使用,以减轻损失。
Wheat yellow dwarf virus is a viral disease caused by the invasion of barley yellow dwarf virus (BYDV). It can damage grasses and various weeds such as barley, wheat, oats, corn, sorghum and millet, Full degree According to our determination, wheat diseased plants can be reduced by 56.2%, 莜 wheat reduced by 37.4%. In recent years, yellow dwarf disease in the country intermittent epidemic harm, causing great losses. In 1981, we collected 83 wheat varieties that have been popularized and applied in Inner Mongolia for identification of inoculation and selected some comparatively disease-resistant and disease-resistant varieties for production adjustment according to local conditions in order to reduce losses.
