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.
