| 摘 要： | 从４个不同地区收集的油菜菌核病菌中，构建了１５个子囊孢子单孢菌系，对其致病力进行了研究。结果表明，供试的１５个单孢菌株在油菜品种上的致病力明显不同，同一来源的１０个子囊孢子间也存在明显的致病性差异，菌株间的致病性差异能长期稳定地存在。

| Abstract: | Fifteen ascospore isolates of Sclerotinia sclerotiorum were established from the collection from 4 different regions and their pathogenicity was tested. The virulence of these ascospores on rapeseed leaves was significantly different. Marked difference in pathogenicity was also observed among 10 ascospores of the same source. Such difference in pathogenicity among different strains seemed stable and is expected to exist for a long time. |
