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

选择2个番茄红素含量显著不同的鲜食番茄品系，通过P₁、P₂、F₁、F₂、B₁和B₂6世代联合分析法，研究分析了番茄红素的遗传规律。结果表明：番茄红素的遗传符合一个主基因和加性－显性－上位性多基因模型，主基因遗传力在B₁、B₂和F₂分别为6.85%、34.78％和58.33％，多基因遗传力在B₁、B₂和F₂分别为58.48％、30.69％和0。

Analysis on the Major Gene and Polygene Mixed Inheritance of Lycopene Content in Fresh Consumptive Tomato Fruit<A title=

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.
