从新疆各地的棉花黄萎病株上共分离到30 个野生型棉花黄萎病菌菌株,以及陕西省植保所提供T9 、VD8 、安阳菌株及泾阳菌株,经在WAC 培养基上诱发培养,34 个菌株共获得431 个突变体,其中114 个为NitM,占26 .45 % ,317 个为Nitl,占73 .55 % 。经营养体亲和性配对测试,32 个菌株可分为2 个营养亲合群(VCGs) ,T9 与VD8 属于亲合群Ⅰ(VCG1) ,其余30 个菌株属于亲合群Ⅱ(VCG2) ,落叶型菌株与非落叶型菌株分属于不同的营养亲合群,新疆棉花黄萎病菌基本属于亲和群Ⅱ(VCG2) 。 Thirty wild type strains of Verticillium dahliae were isolated from cotton plants in Xinjiang and T9, VD8, Anyang and Jingyang strains were obtained from Shaanxi Provincial Plant Protection Institute, and were induced on WAC medium A total of 431 mutants were obtained from 34 isolates, of which 114 were NitM, accounting for 26.45% and 317 were Nitl, accounting for 73.55%. Twenty-two isolates could be divided into two nutrient affinity groups (VCGs), T9 and VD8 belonged to VCG1, and the remaining 30 belonged to VCG2. , The deciduous and non-deciduous strains belonged to different nutrient affinity groups, and the species of Verticillium dahliae in Xinjiang basically belonged to the affinity group II (VCG2).
