抄録

In tests on pathogenicity of Verticillium dahliae and V. longisporum on broccoli and cauliflower, varietal resistance and control after incorporating broccoli residues into artificially infested soil, broccoli cultivars differed in their susceptibility to V. longisporum. All cultivars of cauliflower, however, were very susceptible. V. dahliae was weakly pathogenic to broccoli, weakly or moderately to cauliflower. V. longisporum was isolated from five cultivars of broccoli cultivated in a field severely infested with Verticillium wilt of cabbage. In two cultivars of cauliflower, V. longisporum and V. dahliae were isolated from the same stock. The Brassica oleracea group, such as broccoli and cauliflower, did not induce external wilting symptoms, even if internal symptoms (discoloration of vascular bundle) were severe. When fresh broccoli residues (600kg/a) and diseased cabbage residues were incorporated into the soil, control of Verticillium wilt of cabbage during the next year was better than that with no residues. In a field severely infested with the Verticillium pathogens, commercial growing is possible by using resistant cultivars of broccoli. In addition, Verticillium wilt of cabbage can be controlled by incorporating broccoli residues after harvesting.
