| 摘 要： | 以强雌性苦瓜品系09C-51、09C-54和普通性型品系09C-57为亲本配制杂交组合，调查单株主茎50节位内的雌花节率。通过对两个组合的P1、P2、F1、F2、BC1P1各世代植株的性型观察，并经χ2 测验，表明苦瓜强雌性性状由1对不完全显性基因控制。利用组合09C-51×09C-57的Pl、P2、Fl、F2群体的性型分离数据，进一步对性型进行数量遗传学分析，表明强雌性性状符合1对显性主基因+加性-显性多基因模型，说明苦瓜强雌性性状由1对主基因控制，且存在微效多基因的影响，其主基因遗传率为63.06%，多基因遗传率为26.96%。

| Abstract: | Subgynoecious bitter melon（Momoridca charantia L.）line 09C-51，09C-54 and normal sexual line 09C-57 were crossed in this study．Female flower proportion within 50 nodes for each plant was counted．Through investigation and χ2 test of P1，P2，F1，F2，BC1P1 types in segregating population， found that the subgynoecious trait was controlled by one pair of incomplete dominant gene．Further more，by quantitative genetics analysis of the 09C-51，09C-57 and their P1，P2，Fl，F2 population，the subgynoecious inheritance was proved to correspond with major gene and polygene mixed inheritance model．The heritability of the major gene was 63.06% and that of polygenes was 26.96%. |
