Inheritance of Cherry Tomato Fruit Color

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.
