Anthracnose of pepper casued by Colletotrichum spp. has been a great problems for pepper production in Korea and China. Especially Colletotrichum gloeosporioides was found predominantly over cultivation areas during infection periods and caused severe rots on both unripe and ripe fruits that resulted in major yield losses. In this study, comparison of Colletotrichum spp. isolated from Korea and China in morphology and pathgenicity, and RAPD-PCR analysis were conducted. Based on morphological characteristics, the pathogen isolates, K1 and C1, K2 and C2, and K3 and C3 were identified as Colletotrichum gloeosporioides (G) type, C gloeosporioides (R) type and C coccodes, respectively. In pathogenicity test, K1 and C1, and K2 and C2 were found to attack mainly fruits and to be the most virulent among isolates. K3 and C3 were strongly virulent to leaves and seedling. Pathogenicity between Korean and Chinese isolates did not show any difference. Results of the RAPD-PCR analyses indicate the varying levels of molecular diversity within and between Colletotrichum spp. of Korea and China. The similarities between K1 and C1, K2 and C2, and K3 and C3 were 85.71%, 71.43% and 50.0%, respectively.
