1978年全国小麦锈病防治研究协作组,根据国内自四十年代以来的研究结果,按地理位置将我国小麦条锈菌(Puccinia striformis)越夏区划分成西北、华北、西南三大片。西北片有5个主要越夏区;华北片有2个越夏区;西南片仅1981年黄光明报道,存四川境内的阿坝、甘孜、凉山3个州存在着较多的越夏菌源。 云南地处西南边陲,地貌复杂,层状结构明显,小麦呈垂直分布。自六十年代以来,小麦条锈病曾于1963、1973、1979、1980、1981年度发生过五次大流行,是小麦条锈病 According to the domestic research results of wheat rust prevention and control in 1978, according to the domestic research results from the 1940s, the more summer region of Puccinia striformis in China was divided into three major areas: Northwest, North China and Southwest China. There are 5 main summer regions in the northwest and 2 summer regions in the North China. In 1981, Huang Guangming reported in southwest China that there are more summer bacteria sources in Aba, Garze and Liangshan in Sichuan. Yunnan is located in the southwest border, complex landscape, obvious layered structure, vertical distribution of wheat. Since the 1960s, wheat stripe rust occurred in five major epidemics in 1963, 1973, 1979, 1980 and 1981 and was the stripe rust of wheat
