    摘要:

    以栽培甜瓜‘0246’为母本,野生甜瓜‘Y101’为父本,构建了P1 、P2 、F1 、F2 、B1 、B2六个世代,运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,探讨甜瓜果实糖含量相关性状的遗传特性。结果表明:果糖含量、葡萄糖含量和总糖含量遗传均受两对加性-显性-上位性主基因+加性-显性-上位性多基因模型控制(E-0),主基因在F2中的遗传率分别达到90.32%、82.42%和94.66%。蔗糖含量受一对加性主基因+加性-显性多基因模型控制(D-2),主基因在F2中的遗传率达到83.76%。甜瓜果实糖含量相关性状遗传体系中主基因具有重要作用且环境方差所占比例较小,适宜早代选择。

    Abstract:

    Six generations(P1 、P2 、F1 、F2 、B1 、B2 )derived from a cross of ‘0246’(cultivated inbred line)and‘Y101’(wild germplasm)were used to study the inheritance of melon(Cucumis melo L.)fruit sugar content correlated traits , with joint analysis method of mixed major gene plus polygene inheritance model. The results showed that fructose content, glucose content and total sugar content were controlled by two pairs of additive-dominant-epistatic major genes plus additive-dominant-epistatic polygene model effects (E-0),and the heritabilities of major genes in F2 population were estimated as 90.32%,.82.42% and 94.66%,respectively. The sucrose content was controlled by one pairs of additive major genes plus additive-dominant polygene model effects (D-2),and the heritability of major genes in F2 population was estimated as 83.76%. This implied that the major genes had strong effects on fruit sugar content correlated traits of melon,while the environment played a little role, so it would be more efficient to be selected in the early generation.
