摘要：应用植物数量性状主基因+多基因混合遗传模型,对花生品种"青苗豆×全州麻壳"、"富川大花生×隆安宝湾花生"和"汕油162×Sunoleic95R"三个不同杂交组合的F2分离群体的油酸/亚油酸比值进行了单个分离世代的数量性状分离分析,结果表明:"青苗豆×全州麻壳"、"富川大花生×隆安宝湾花生"两个杂交组合结果一致,O/L受一对负向完全显性的主基因控制,F2群体表现为由主基因型AA和Aa+aa按1∶3比例的混合;另一个组合"汕油162×Sunoleic95R"的油酸/亚油酸比值受两对加性-显性-上位性主基因控制,两对主基因间的基因效应差异不大。第一对主基因加性效应(da)1.3586和第二对主基因加性效应(db)1.3580几乎相同。三个组合的主基因遗传力分别为61.27%、64.09%和64.66%,多基因的遗传力分别为33.85%、34.52%和33.45%。
Inheritance of the ratio of oleic acid to linoleic acid in peanut in three crosses of ＂Qingmiaodou X Quanzhoumake ＂, ＂Fuchuanda peanut ×Longanbao peanut ＂ and ＂Shanyou 162 X Sunoleic95R＂was investigated by applying the major gene plus poly-genes model of quantitative traits to a segregation analysis of single-generation F2. The results showed that the ratio of oleic acid to linoleic acid in two crosses of＂Qingmiaodou × Quanzhoumake＂,＂Fuchuanda peanut × Longanbao peanu＂was controlled by one major gene with minus dominance effect plus ploygenes and that the ratio of oleic acid to linoleic acid in cross of＂Shanyou 162×Sunoleic95R＂was controlled by two major genes with additive-dominanceepistatic effects plus ploy-genes, the estimated additive effects of the two major genes, da and db were 1. 3586.1. 3580,respectively. Heritability values of the major genes of three crosses were estimated as 61.27% 33.45% Key , 64. 09% and 64. 66%,respectively, while those of polygenes were 33. 85%, 34. 52% and , respectively.
