| 摘 要： | Eight hundred twenty four nit mutants were induced from 73 strains of Fusarium oxysporum f. sp. vanillae, and classified into four phenotypes by their abilities to utilize different nitrogen sources. Among these mutants, 64.9% were characterized as nit 1, 24.3% as nit 3, 9.8% as nit M, 1.0% as nit X. Based on complementary pairing tests of different nit mutants on the medium MM, 44 isolates belonged to 8 different VCGs, 29 isolates were classified into single and different VCGs. These results indicated that there was significant VCG diversity in Fusarium oxysporum f. sp. vanillae population. VCGs might be correlated with geographic origin of strains, but no close correlation was found between VCGs and pathogenicity.
