Genetic characteristics of Korean Fusarium oxysporum f. sp. lycopersici isolates, casual organisms of Fusarium wilt on tomato, were analyzed using RFLP analysis to compare those with foreign isolates. Correlation between the result of RFLP analysis and VCG, race of the isolates was also revealed. Distinct genetic differences in numbers and patterns of RFLP bands were detected between isolates obtained from Korea, America and Japan. It demonstrated that Korean isolates were genetically very stable despite the difference of their geographical origins each other. Southern hybridization band patterns were unique with the vegetative compatibility group and highly correlated with VCG and genetic character. No correlation, however, was detected between VCG and race in this pathogen. Base on the result of the same band patterns of all Korean isolates, it was possible to assume that they are belong to the one VCG. Remarkably different cluster was formed between Korean and foreign isolates in UPGMA analysis.
