小麦黄矮病为我区小麦上的重要病害,影响小麦的高产稳产,在流行年份,产量损失严重,如1970年我区为特大流行年,据不完全统计,一般减产30%以上,严重地区减产高达60%或至毁种。目前许多国家对本病在防除策略上,多采用以抗病品种为主的综合防治措施。1973～1978年,我们采用田间小区试验和自然发病调查相结合,研究抗病性的鉴定方 Wheat yellow dwarf disease is an important disease on wheat in our district, affecting the high and stable yield of wheat. In the popular year, the yield loss is serious. For example, in 1970, the district was a pandemic. According to incomplete statistics, the output was reduced by more than 30% Cut as much as 60% or destroy the species. At present, many countries on the prevention and control strategies in this disease, the use of multi-resistant varieties of integrated control measures. From 1973 to 1978, we used a combination of field plot tests and natural disease surveys to study the identification of disease resistance
