摘要
以栽培大豆铁豆67为母本,半野生大豆YZ1621为父本,进行有性杂交,构建大豆种间杂交F2代遗传群体,对群体蛋白质含量、脂肪含量及蛋脂总量等遗传参数进行了分析。结果表明:大豆种间杂交F2代蛋白质含量、脂肪含量及蛋脂总量的遗传分离为连续离散分布,符合正态分布,其中,脂肪含量和蛋脂总量表现出倾向高值亲本的正态分布;三性状超中亲遗传普遍存在,蛋脂总量超高亲遗传显著,超高亲比例达到66.7%;三性状的遗传方差、标准差均较小,变异系数分别为4.04%、5.13%、2.67%,表明群体内个体间的变异度不高;三性状广义遗传力均达到了55.0%以上。
The genetic parameters of protein content, oil content and total protein-oil content were analyzed on F2 population derived from the cross of Tiedou 67 and a semi-wild soybean YZ1621 in this study. The results were as follows：The genetic segregation of protein content, oil content and total protein-oil content of F2 population was in accord with normal frequency distribution, and which oil content and total protein-oil content also leaned to higher parent. It existed generally over mid-par- ent inheritance in 3 characters, and the transgressive inheritance was significant in total protein-oil content with 66.7% plants over the higher parent in F2 population. Variable coefficients of protein content, oil content and total protein-oil content were 4. 04% ,5.13% and 2. 67% respectively, which indicated that variable degree of main quality characters were all very low. The broad hereditability of 3 characters were all higher than 55.0%.
