The Fusarium wilt-resistant capasity of sweetpotato (FWSP) was tested in 443 sweetpotato varietiesin south China with an artificial inoculating method.Results showed that, 2 varieties are highly resistant(HR); 30 varieties resistant (R); 49 varieties moderately resistant (MR); 96 varieties moderately sensitive(MS); 62 varieties sensitive (S) and 204 varieties highly sensitive (HS).The repeat test to MR or R or HRvarieties gave an identical result and indicated that the resistance of these varieties to FWSP issteady.Simultanneously, the identification by field infection has been undertaken.Most of the varieties showedlow morbidity than that of Pot inoculation, among which 12 varieties were highly resistant (HR).The relationship between resistance and yield of sweetpotato was preliminarily studied.The development of the root tubersof sweetpotato was greatly affected by FWSP.
