Pepper anthracnose Collectotrichum spp. Is an important disease of chili in Korea and China.The morphological characteristics of three strains of Korean anthrax and three kinds of Chinese anthracnose were compared and the pathogenicity was identified.The results are as follows: (1) Morphological characteristics, K1 and C1, K2 and C2 and K3 and C3 were identified as Colletotrichum gloeosporioides G type, C. gloeosporioides R type and C. coccodes; (2) There was no significant difference between the pathogenicity of Korean strain and Chinese strain (3) The results of RAPD-PCR analysis showed that the similarity rates of K1 and C1, K2 and C2, and K3 and C3 were 85.71%, 71.4 3%, and 50%, respectively.
