摘　　要：采用Ｇｒｉｆｆｉｎｇ双列杂交方法Ⅱ，对西瓜枯萎病具有不同抗性的７个品种之后代的抗性表现进行研究，结果表明：酉瓜品种对枯萎病的抗性属数量性状，抗病性由隐性多基因控制，其遗传效应符合“加性－显性”模型，以加性效应为主，且感病对抗病表现部分显性（抗病对感病表现部分隐性）。The inheritance of resistance to fusarium wilt(Fusarium oxysporum f. sp.niveum strain FW 8801)in watermelon was studied by analyzing the F1 genetration of teh according to Griffing's diallel crossing system Ⅱ,Seven inbred cultivars withe variant resistance were selected to make the crosses.Soil inoculation was used to evaluated teh results obtained indicate that the inheritance of resistance in watermelon conforms to the additive-dominance model.The analysis of Wr+Vr showed that the additive effect was major and the susceptibility was partially dominant.
