中文摘要：

利用雌雄异花同株品系3-2-2和雄全同株品系TopMark为亲本,配置杂交组合,获得6世代群体（P1,P2,F1,F2,BC1P1,BC1P2）,调查定植后第1朵雌花开放到定植后60d内的雌花率,通过主-多基因混合模型分析其遗传效应。结果表明：甜瓜雌雄异花同株植株杂交后代雌花率受到1对主效基因控制,同时存在2对微效基因,主基因遗传率为83.33%,微效基因的遗传率为8.125%,同时讨论了利用雌花率分析雌雄异花同株遗传规律的可行性。

英文摘要：

Using monoecious line 3-2-2 and monoecious line TopMark as parental melon（Cucumis melo L.）to acquired six generations（P1,P2,F1,F2,BC1P1,BC1P2）in this study.Investigated and analyzed the inheritance of female flower proportion from the fist female flower opening to 60 days after transplanted using by major gene and polygene mixed inheritance model.The results indicated that female flower proportion on monoecious plant was controlled by a single major gene with 2 minor genes,the major gene effect was 83.33% and the minor gene effects were 8.125%,respectively.And in this study we also discussed the feasibility of using female flower proportion to analysis the inheritance of monoecy on melon.
