    Inheritance Analysis and Mapping QTL on Fat Content Trait in Soybean

      摘要
    • 摘要: 以高蛋白大豆品种吉育50和高油大豆品种吉农18杂交后获得的F2及其衍生群体为材料，采用主基因＋多基因混合遗传模型和QTL IciMapping v2.2完备区间作图法研究大豆脂肪含量的遗传规律．结果表明：大豆脂肪含量表现为多基因遗传模型，主要受多基因控制，多基因遗传率为79.15%；对大豆脂肪含量进行QTL定位和分析，共检测到2个主效QTL和2个微效QTL，分布于12(G)、17(M)和22(F) 3个连锁群上，其中包括了1个在2年间稳定存在的主效QTL．

       

      Abstract: Major genes plus polygene mixed inheritance model and QTL IciMapping v2.2 Inclusive Composite Interval Mapping were used to study the genetic regulation of soybean fat content in F2 segregating population materials of high protein Jiyu50 and high fat Jinong18 parents. The results showed that the soybean fat content trait complied with the polygenic inheritance model and was controlled by polygene. Polygene genetic rate was 79.15%. Two major effective QTLs and two micro effective QTLs on soybean fat content were detected and distributed in 12 (G), 17 (M) and 22 (F) 3 linkage groups, including a stable major QTL in two years.
