Abstract: Hybrid combinations were made with three inbred lines of different fruit color. Fruit color was classed by color difference meter and ocular measurement. Their six generations F₁, F₂, backcrosses B₁ and B₂ and their parents P₁ and P₂ were used to study the inheritance of eggplant fruit color traits with joint analysis of multiple generations. The results were the followings: the F₂ population of the three combinations appeared two peaks or one peak distribution, indicating that eggplant trait was quantitative in nature and controlled by polygene. The inheritance of fruit color fitted the additive-dominance-epitasis major gene plus additive-dominance-epitasis polygene (E Model).The major gene heritability is higher，between 35.5% and 98.4%；The polygene heritability is lower，between 0 and 57.7%.
