小麦黄矮病(BYDV)是我国北方麦区主要的病毒病,特别在干旱、半干旱地区,是低产小麦稳产丰产的重大障碍之一。关于小麦黄矮病的综合防治,除研究采取有效的治蚜防病措施外,最根本的具有战略性的,就是选用抗、耐病丰产品种。1973年该病历史上第3次大面积流行后,就开展了小麦品种抗病性研究工作,根据对1983和1984年田间人工鉴定的2050份重要小麦品种资源,及以往室内外人工鉴定的557份材料的结果分析归纳,试论小麦抗黄矮病毒鉴定的以下有关问题:
Wheat yellow dwarf virus (BYDV) is one of the major viral diseases in northern China wheat fields, especially in the arid and semi-arid regions. It is one of the major obstacles to the stable yield and high yield of low-yielding wheat. On the comprehensive control of wheat yellow dwarf disease, in addition to effective measures to cure aphids disease prevention, the most fundamental strategic is the selection of anti-disease and disease-resistant varieties. After the third large-scale epidemic in the history of the disease in 1973, the research on the disease resistance of wheat cultivars was carried out. According to the resources of 2050 important wheat cultivars appraised in the field in 1983 and 1984 and 557 Analysis of the results of the analysis of the ingredients, wheat anti-yellow dwarf virus identification on the following issues:
