小麦赤霉病是长江中下游小麦生产上的主要病害,发生频率高、为害损失重。据解放以来在江苏15个赤霉病流行年的统计,减产常达2—4成,是小麦高产、稳产的严重障碍。对赤霉病的练合防治,过去一直认为赤霉病没有免疫品种,选育高产抗病品种是希望不大的。但从小麦品种资源在田间的反应看,品种间对小麦赤霉病的抗性确具有明显差异。如果从中筛选抗源,并通过抗性转育,培育具一般抗性而综合性状好的小麦品种
Wheat scab is the main disease in the production of wheat in the middle and lower reaches of the Yangtze River, with high frequency and heavy damage. According to the statistics of the epidemic year of 15 scab in Jiangsu since the liberation, the annual output is often reduced to 2-4 percent, which is a serious obstacle to high yield and stable yield of wheat. Fungus prevention and treatment of scab disease, the past has always been that there is no blight scab varieties, breeding high yield of resistant varieties is not much hope. However, judging from the reaction of wheat germplasm resources in the field, there is a clear difference in the resistance to wheat scab among the cultivars. If the screening of anti-source, and through resistance to breed, with general resistance to cultivate good traits of wheat varieties
