Analysis on the Major Gene and Polygene Mixed Inheritance of Lycopene Content in Fresh Consumptive Tomato Fruit
鲜食番茄果实中番茄红素含量的主基因－多基因混合遗传分析

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 additive-dominance-epistasis polygenes dominate the inheritance of lycopene in fresh consumption tomato. The major gene heritability in B1, B2 and F2 was 6.85%, 34.78 % and 58.33 %, respectively, and the polygene heritability was 58.48%, 30.69% and 0, correspondingly.
