Two eggplant inbred lines are materials, whose fruit calyx color is green and purple respectively ,the color board classified the calyx color,the inheritance of eggplant fruit calyx color were studyed with P1,P2,F1,B1,B2 and F2 . The results showed that calyx color grade value of F2 is single peak and partial distribution, it is proved that the fruit calyx color is quantitative trait controlled by multiple genes. The inheritance of eggplant fruit calyx color is controlled by two additive-dominant-epistatic major gene additive-dominant-epistatic polygene model(E-0 Modle) . It with high main gene heritability is 96.82% which can be used in breeding.
