利用野生型大豆ZYD00006(供体亲本)与主栽品种绥农14(轮回亲本)所构建的高世代回交导入系,经过严格的百粒重筛选鉴定,得到43个百粒重性状明显小于轮回亲本的导入系个体。利用这套选择群体结合随机对照群体和基因型分析,通过基于遗传搭车原理的卡方分析,检测到分布于7个连锁群上的9个与大豆小粒性状相关的QTL位点,对小粒性状表现为正效应,为大豆小粒性状分子辅助育种提供有用的分子标记。 The high-generation backcross inbred lines constructed with wild-type soybean ZYD00006 (donor parent) and the main cultivar Suinong 14 (reincarnated parent) were screened through strict selection of 100-kernel weight to obtain 43 hundred kernel weight traits significantly less than the reincarnation The introduction of the parental line of the individual. Based on the random selection population and genotype analysis, nine QTLs associated with soybean grain traits distributed on seven linkage groups were detected by chi-square analysis based on hedging principle. As a positive effect, the soybean grain traits molecular assisted breeding to provide useful molecular markers.
