| 中文摘要: |
| 蚕豆赤斑病是蚕豆的重要病害之一，严重影响蚕豆生产。本研究通过形态学和分子特征，对采自甘肃、青海、江苏、四川、河北、重庆等6个省市的蚕豆赤斑病病原菌进行鉴定。结果表明，在6个省市均鉴定到蚕豆葡萄孢（Botrytis fabae）、灰葡萄孢（B. cinerea）和拟蚕豆葡萄孢（B.fabiopsis）3种病原菌。致病力测定表明：不同地理来源的3种病原菌分离物都存在致病力差异，但均以强致病力分离物为主。本研究是继湖北省之后在其他省市首次发现拟蚕豆葡萄孢。 |
| 英文摘要: |
| Chocolate spot is one of the most important diseases on broad bean, causing severe yield loss in China. In this study, the pathogens for chocolate spot of broad bean were isolated from Gansu, Qinghai, Jiangsu, Sichuan, Hebei and Chongqing provinces and were identified on the basis of the morphological and molecular characteristics. Three Botrytis species, namely B. fabae, B. cinerea and B. fabiopsis,were found in all of the surveyed provinces. The isolates of each species differed greatly in pathogenicity. However, most isolates of each species showed strong pathogenicity on broad bean. To our knowledge, this is the first report of B. fabiopsis in other provinces of our country since the nomenclature of this species in Hubei Province. |
