摘　　要：以中国南瓜强雌系F81和普通性型株系M32为试验材料,构建6世代群体,连续两季调查25节以内的雌花节率,采用多世代联合分析法分析中国南瓜强雌性状遗传效应。结果表明:中国南瓜强雌性状的遗传符合C-1模型,受1对主基因+多基因控制,主基因为正向作用,多基因作用可以忽略不计;同时,雌花节率受环境的影响较大。Taking Chinese pumpkin strong female line‘F81’and common sex type pumpkin‘M32’as test materials,this study constructed six-generation population,investigated the female flower node rate within 25 nodes for 2 consecutive seasons,and analyzed the genetic effects of strong femaleness on Chinese pumpkin by multi-generation joint analysis method.The results showed that Chinese pumpkin strong femaleness conformed to C-1 model,which was controlled by a pair of major genes and polygenes.The major gene had a positive effect,and effect of polygene could be ignored.At the same time,female flower node rate was affected by environment.
