多抗、优质、高产小麦的引进和培育条锈和白粉菌的致病性变异快,新出现的条中28号小种主要侵染具欧洲黑麦亲缘的高加索、阿芙乐尔、洛夫林系统的品种,而我国小麦的部分推广品种和大部分后备品种具欧洲黑麦亲缘。白粉菌64号小种能侵染我国所有小麦的推广品种和后备品种。为此,贵州农学院曾从国外引入一批普通小麦品种,对我国条、叶、秆锈病和白粉病菌的优势小种均具抗性,特别是对条锈菌条中28号小种、白粉菌64号小种、叶锈菌叶中20号具有抗性;用作抗 Multi-resistant, high-quality, high-yielding wheat introduced and nurtured the stripe rust and pathogenicity of the powdery mildew. The newly emerged race 28 invaded Caucasus, Aurora, Love Forest system varieties, and some of our wheat varieties and most of the backup varieties of European rye kinship. Powdery mildew 64 breeds can infect all varieties of wheat and backup varieties in China. To this end, Guizhou Agricultural College has introduced a number of common wheat varieties from abroad, which are resistant to the dominant races of bar, leaf and stem rust and powdery mildew in China, especially for race 28, Bacteria 64 race, leaf rust leaves No. 20 is resistant; used as anti
