| Abstract: | We tested different spore concentration(1×105,1×106,1×107 spore·mL-1)and seedling stage(cotyledon stage,2 true leaf stage and 4 true leaf stage)to develop a seedling test protocol for melon resistance to Fusarium wilt(Fusarium oxysporum f.sp.melonis).The best concentration for inoculation is 1×106 spore·mL-1 and the best inoculation time is at 2 true leaf stage.The best time for resistance evaluation is 10 days after inoculation.The optimized protocol was used to 18 melon cultivars for resistance to Fusarium wilt.Cultivars Xinjinxuelian,Changxiangyu,Yugu,Chunhui and Mil had high resistance to melon Fusarium wilt. |
