Analysis on the major gene and polygene mixed inheritance of lycopene content in fresh consumptive tomato fruit

Two cultivars significantly different in lycopene content were used for the study of inheritance pattern of lycopene content in fresh consumptive tomato fruit.Combination analysis of six generations proved that a major gene plus additivedominance-epistasis polygenes dominate the inheritance of lycopene in fresh consumption tomato.The major gene heritability in B_1,B_2 and F_2 was 6.85%,34.78% and 58.33%,respectively,and the polygene heritability was 58.48%,30.69% and 0,correspondingly.
