Four eggplant inbred lines with different colors in flower，peel and flesh were used as experimental materials，which were crossed in three hybrid combinations and through backcrossing and selfing produced six generation populations，for the study of the genetic relationships among eggplant flower color，peel color and flesh color，the aim of this study was to enrich the genetic research on peel color and flesh color of eggplant，and to provide theoretical basis for the breeding of new eggplant varieties. The results indicated that the flower color was controlled by a pair of genes，with purple fully dominant to white. The peel color was controlled by two pairs of dominant genes with overlapping effect，and the purple gene had dominant epistatic effect. Peel purple was dominant to green，and the purple gene of eggplant peel color inhibited the expression of the green gene. The flesh color was controlled by a pair of genes，with green-white fully dominant to white. There was the gene interaction effect in the inheritance of eggplant peel color and flesh color. The green-white gene controlling eggplant flesh had an epistatic effect on the white gene controlling eggplant peel，the inheritance of eggplant flower color and peel color were not completely linked，the crossing-over value of white flower with green peel and purple flower with purple peel being 20.5%，and the crossing-over value of white flower with white peel and purple flower with purple peel being 34.6%，the flower color and flesh color of eggplant were in accordance with the independent genetic law in the process of hybrid inheritance，and there was no linkage relationship.
