不同抗性品种对棉花黄萎病菌致病力的影响
Effect of Host Resistance on the Pathogenicity of Verticillium dahliae Isolates
摘要
Abstract
Sixty-seven isolates of Verticillium dahliae were obtained from infected cottons, a Gossypium barbadense cultivar and 15 Gossypium hirsutum cultivars. Pima90-53 and Jimian20 with resistance to Verticillium dahliae, Han208 and CCRI 8 with susceptibility, were used to assess the pathogenicity of the fungal isolates. We found that highly diverse pathogenic types from weak to strong existed in continuity in the same cotton field, and the pathogenic variation of isolates was very significant among populations from different cotton varieties. The resistance of hosts to Verticillium wilt did not influence the pathogenicity of isolates, however host selection may affect the population genetic structure of isolates.关键词
