摘要
以中、美、日、韩 4国大豆品种作亲本 ,组配成中×美、美×中、中×日、中×韩、中×中等 2 1个杂交组合 ,对F2 代农艺性状的相关、通径进行分析。结果表明 :单株荚数、单株粒数与单株产量呈极显著正相关 ;百粒重与单株产量相关不明显 ,与单株荚数。
hybridized combinations of soybean, whose parents from China, America, Japan and Korea respectively,were studied on genetic variation of agronomic character in F 2 generation The results showed that: Pod and seeds per individual plant have positive correlation with yield per plant, while 100 grain weight and yield per plant have no significantly correlation, and there were negative correlation between 100 grain weight, pod and seeds per plant
