Abstract The heterosis,parent-offspring correlation between 21 hybrids and their parent lines of chieh-qua (Benincasa hispida Cogn.var.chieh-qua How.) were investigated.The results showed that heterosis of fruit weight and yield was highest,followed by fruit soluble solid content,fruit index,fruit diameter and fruit length,the heterosis of fruit thickness was lowest.Yield of F_1 had significant positive correlationship with that of male parent and mid-parent; fruit length of F_1 had very significant positive correla...
