| Abstract: | Corynespora leaf spot on balsam pear in greenhouse is one of the serious diseases in Nanning city, Guangxi province. The pathogen was purified and then identified based on pathogenicity test, morphological characteristics observation and rDNA-ITS sequences analysis. And the cassiicolin subtypes and of isolates were analyzed by using specific primers of cassiicolin. The results indicated that the pathogen was identified as Corynespora cassiicola. Among the 15 isolates, 11 isolates of C. cassiicola contained Cas2 protein and 4 isolates of C. cassiicola contained Cas0. |
