摘要
1996～ 1 998年从新疆各主要植棉区采集 3 0个野生型棉花黄萎病菌菌株 ,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 ,3 4个菌株共获得 4 3 1个突变体 ,其中 1 1 4个为Nit M,占 2 6.4 5%,3 1 7个为 Nitl,占 73 .55%。经营养体亲和性配对测试 ,3 2个菌株可分为 2个营养亲合群( VCGs) ,T-9与 VD-8属于亲合群 ( VCG1 ) ,其余 3 0个菌株属于亲合群 ( VCG2 ) ,即落叶型菌株与非落叶型菌株分属于不同的营养亲合群 ,还有 2个菌株即安阳菌株和 1 3 6团菌株因不与任何菌株亲和 ,故暂未定亲和群。由此可见 ,新疆棉花黄萎病菌的类型比较单一 ,除个别菌株外基本属于同一亲和群 ( VCG2 )
The 30 strains of Verticillium dahliae of cotton collected in Xinjiang from 1996 to 1998 and 4 strains from Institute of Plant Protection Shaanxi Academy of Agricultural Science were studied for vegetative compatibility test.There were about 434 mutants obtained from 34 strains induced on WAC media, in which 114 mutants were NitM,the others were NiL. All except two strains, could be assigned to one vegetative compatibility group designated VCG 2. Strain T 9 and VD 8 belonged to VCG 1,which indicated that strains of Verticillium dahliae of cotton in Xinjiang basically belonged to vegetative compatibility group Ⅱ.
