我省冬小麦(Tv.aestirum)生育期间一般气候温和,阴雨较多,湿度较大,故白粉病(Erysiphe graminis f.sp.tritici)对小麦的危害普遍而又严重。近年来小麦白粉病在我国长江中下游及淮河流域发病亦较普遍,有的年份因施肥水平和播种密度高,危害亦较严重。为了较快的选育抗病、高产稳产的小麦新品种,研究小麦对白粉病抗性的遗传规律是十分重要的,我们于79～82年对小麦抗白粉病性的遗传进行了探索。
The winter wheat (Tv.aestirum) in our province generally mild climate during the growth, more rainy, humid, so powdery mildew (Erysiphe graminis f.sp.tritici) on the general and serious damage to wheat. In recent years, the incidence of wheat powdery mildew in the middle and lower reaches of the Yangtze River in China and the Huaihe River Basin is also more common in some years due to high levels of fertilizer and seeding, the more serious harm. It is very important to study the genetic law of wheat resistance to powdery mildew in order to breed new wheat varieties with high and stable yield quickly, and to explore the inheritance of wheat powdery mildew resistance in 79-82 years.
