Abstract: Various hybrids were generated by crossing among two black, 6red, 4pink, 2orange, and 2yellow cherry tomato inbred lines.The visual fruit color classification for the tomatoes was obtained using a Royal Horticultural Society plant color chart.The phenotypic observation of 6samples was performed on a color difference meter.And, the major plus multi-gene analysis of quantitative traits in plant was used to study the genetic law of the fruit color in black cherry tomato.The results showed that the black fruit color was a recessive trait.The parents must be of black type in order to achieve the same fruit color in hybrid F1.The genetic fruit color trait of the combination, PINK×Z2, was determined by additive-dominant-epistemic model of two major genes, and there was an epistemic effect between the two major genes.
