对来自我国8个省区的3441个小麦农家品种进行抗白粉病鉴定的结果,免疫至高抗的有6个品种,占0.2%。中抗品种71个,占2.0%。根据品种形态性状的异同及其在8个异地鉴定点表现的抗谱,对其中17个抗性较好的品种进行了初步的归类探索,共划分五种类型,分析了类型形成原因,对归类在抗病育种和遗传研究等方面的意义做了初步讨论。
The results of powdery mildew resistance test of 3441 wheat farm breeds from 8 provinces and autonomous regions in China showed that there were 6 breeds resistant to high resistance, accounting for 0.2%. In the anti-71 species, accounting for 2.0%. According to the similarities and differences of morphological characters of cultivars and their anti-spectrum displayed in eight isolates, 17 cultivars with better resistance were initially classified and explored. Five types were divided into five types, and the reasons for their formation were analyzed. The significance of classification in resistance breeding and genetic research has been discussed.
