Forty (40) isolates of Fusarium oxysporum isolated from wilting tomato plants at Buyeo of Korea in 1997 were inoculated to four tomato cultivars (ponderosa, Okitsu 3, Walter, and Zuiken) to examine pathogenic reactions. Isolation rates of F. oxysporum f. sp. lycopersici (FOL) races 1 and 2, and F. oxysporum f. sp. radicis-lycopersici (FORL) were 3.5%, 24.5%, and 57.5%, respectively. Mycelial growth on potato-dextrose agar at different temperatures showed similar patterns, while optimum temperature for the three pathogens was 26℃. In the pathogenicity tests, however, the range of optimum temperature for disease development for FORL was between 15 and 20℃, while that for races 1 and 2 of FOL was between 25 and 30℃. In the host range studies, soybean, string bean and/or cucumber as well as tomato were susceptible to FORL, while races 1 and 2 of FOL were specifically pathogenic to tomato only. This suggests that host ranges of FORL and FOL differ significantly.
