摘要
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B2六世代联合分析法,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。
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.
