Abstract：Taking bitter melon inbred line‘ 29’ and‘ Huizhoudading’ as parent，this study
developed 6 generations（P1，P2，F1，B1，B2，F2）from the cross，and analyzed the inheritance of
single fruit seed number and seed coat color，respectively. The results showed that the single fruit seed
numbers of bitter melon was controlled by 2 pairs of equi-dominant major genes plus additive-dominant
polygenes（E-6 model）．The additive effects and dominant effects of the two major genes were equal.
The dominant effect of polygenes is positive and F1 expresses over-parent heterosis．Seed coat color
of bitter melon was controlled by a pair of dominant genes，black is the completely dominant traits to
