Genetic Diversity of Colletotrichum spp. Causing Grape Anthracnose in Zhejiang, China

Anthracnose is a fungal disease that seriously threatens grape production and quality. Multiple Colletotrichum species are detected in anthracnose grapes vineyards. In this study, diseased were collected four counties Zhejiang, 43 isolates obtained. Multi-genes (ITS, TUB2, ACT, CHS-I, GAPDH) morphological characteristic analyses showed C. fructicola (40 isolates, 93%), aenigma (two 4.7%), pseudoacutatum (one isolate, 2.3%) the cause of Zhejiang. Among three species, was prevalent dominant all sampled counties; first identified as pathogen responsible for anthracnose. There significant differences sporulation among well spore germination. Pathogenicity testing can infect grapes, resulting On other hand, virulence varied may be associated with their This study to characterize causing Zhejiang Province reveal species. The determination contribute epidemiology development an efficient strategy controlling
