Abstract: To clarify the species and distribution of Fusarium species in vegetable growing areas in Hubei province,55 rhizosphere soil samples were collected from 13 cities of Hubei province,and Fusarium species strains from the samples were isolated,purified and identified. Total 271 Fusarium strains were obtained. Among these Fusarium strains,according to molecular biological techniques such as species-specific primers and sequencing,118 strains were identified as Fusarium oxysporum accounting for 43.6% of the total,46 strains as F. equiseti for 17.0% of the total,45 strains as F. commune for 16.6% of the total,31 strains as F. solani for 11.4% of the total,11 strains as F. fujikuroi for 4.1% of the total,6 strains as F. delphinoides for 2.2% of the total,5 strains as F. concentricum for 1.8%,3 strains as F. tricinctum for 1.1%,and 6 strains were Fusarium spp. for 2.2% of the total. Based on the confrontation culture with pathogenic F. oxysporum f. sp. lycopersici strain,16 strains of antagonistic Fusarium species were identified,including 4 strains of F. oxysporum,4 strains of F. solani,3 strains of F. concentricum,and 3 strains of F. tricinctum,while each of F. equiseti and F. fujikuroi was only one,respectively. In this study,the species and diversity of Fusarium species in vegetable producing areas of Hubei province were confirmed,which provides the theoretical basis for the accurate pathogen identification and scientific control of Fusarium disease.
