摘要
以父本200932(果肉橙红色)与母本200930(果肉绿色)为亲本,建立了6个联合世代(P1、P2、F1、F2、BC1P1及BC2P2)群体,采用植物数量性状主基因+多基因混合遗传模型,进行多世代联合分析,探讨甜瓜果肉β-胡萝卜素含量性状的遗传特点。结果表明:组合200930×200932的β-胡萝卜素含量性状遗传受两对加性-显性-上位性主基因+加性-显性多基因模型(E-1)控制,F2群体主基因遗传率为92.66%,多基因遗传率为5.40%,BC1P1群体主基因遗传率为86.80%,多基因遗传率为0,BC2P2群体主基因遗传率为59.88%,多基因遗传率为38.60%。
Six generations(P1,P2,F1,F2,BC1P1 and BC2P2)derived from a cross of 200932(orange flesh)and 200930(green flesh)were used to study the inheritance of melon(Cucumis melo L.)β-carotene content traits by joint analysis method of multiple generations.The results showed that β-carotene content fitted 2 pairs of additive-dominance-epitasis major genes plus additive-dominant polygene model(E-1).The major gene heritability of F2 population was 92.66%,the polygene heritability was 5.40%,The major gene heritability of BC1P1 population was 86.80%,the polygene heritability was 0.The major gene heritability of BC2P2 population was 59.88%,The polygene heritability was 38.60%.
