我国南方麦区,特别是长江中、下游麦区,由于小麦生长后期雨水较多,相对湿度大,有利于麦类真菌病害的发生与流行。这些地区经常严重为害小麦的病害有赤霉病、锈病及白粉病等等。因此选育能抗多种病害的综合抗病性品种,不仅是生产发展的急需要求,亦是小麦育种实践中一个急待解决的理论问题。本文将就选育多抗性的综合抗病品种的目标、方法及原理,提出一些粗浅的看法。
In southern China wheat area, especially in the middle and lower reaches of the Yangtze River, due to more rain and more relative humidity during the late growth of wheat, it is conducive to the occurrence and prevalence of wheat fungal diseases. The diseases of wheat that are often seriously harmed in these areas include scab, rust and powdery mildew. Therefore, breeding a variety of diseases resistant to comprehensive disease-resistant varieties, not only the urgent need for the development of production, wheat breeding is also an urgent theoretical solution to the problem. In this paper, we will put forward some superficial views on the objectives, methods and principles of breeding multi-resistance resistant varieties.
