Abstract:The host range of Fusarium oxysporum f. sp. conglutinans was tested by inoculating conidial suspension by root-dipping method. Experimental results showed that almost the tested cruciferous crops could infected , but the degree of disease severity was different due to different species and varieties, and race2 has a broader host range than race 1. Although non-cruciferous host does not show disease symptoms, but the 13 vegetable species which belongs to 7 families were asymptomatic carrier except shallot. The pathogens mainly existed in roots but can generally move to stems. Cabbage was infected by back inoculated with the isolates ex-tracted from the asymptomatic carrier host. Thus our data show that F. oxysporum f. sp. conglutinans can be colonized in cruciferous as well as in other vegetable crops, making it possible to be infection source of Brassica oleracea in next season.
