【摘要】 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) 。更多还原

【Abstract】 The 30 strains from Xinjiang and 4 strains from Institute of Plant Protection,Shanxi Academy of Agricutural Science were studied.434 mutants obtained from 34 strains which induced on WAC media,in which 114 mutants were NitM,the others were Nitl.All,except two strains,could be assigned to one of two vegetative compatibility groups designated VCG1,VCG2.Strain T 9 and VD 8 belong to VCG1,others were assigned to VCG2.Xinjiang cotton wilt from Cotton in Xinjiang$$$$ Huo Xiangdong\ Li Guoying Zhang Li (Dept of Agri Science,Agri Col,Shihezi Univ,Shihezi 832003) \;Abstract\ The 30 strains from Xinjiang and 4 strains from Institute of Plant Protection,Shanxi Academy of Agricutural Science were studied.434 mutants obtained from 34 strains which induced on WAC media,in which 114 mutants were NitM,the others were Nitl.All,except two strains,could be assigned to one of two vegetative compatibility groups designated VCG1,VCG2.Strain T 9 and VD 8 belong to VCG1,others were assigned to VCG2.Xinjiang cotton wilt Verticillium dahliae basically belongs to vegetative compatibility group Ⅱ.\;更多还原
