新疆棉花黄萎病菌致病性分化的研究

Pathogenic Differentiation of Verticillium dahliae from Cotton in XinJiang

对新疆主要植棉区的 30个棉花黄萎病菌菌株及陕西省农科院植保所赠送的 4个标准菌株进行致病性分化和营养亲和性研究。结果表明 ,新疆棉花黄萎病菌致病性分化明显 ,可分为强、中、弱3种类型 ,34个菌株中的 32个菌株可分为 2个亲合群 。

The paper focused on pathogenic differentiation and vegetative compatibility of 30 strains from the main cotton productive regions in Xinjiang and 4 strains from Institute of Plant Protection of Shanxi Academic of Agricutural Sciences. The pathogenic differentiation of strains from Xinjiang is obvious, 30 strains could be divided into three patho types as:strong,mild,weak.All tested strains,except two, could be assigned to one of two vegetative compatibility groups.
