Abstract：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．
