以14个大豆品种为试材,对7个数量性状进行相关遗传力和通径分析。结果表明,对单株粒重进行直接选择效果较好;株高和百粒重与单株粒重的相关遗传力虽然较小,但对单株粒重的直接作用最大,主要是单株英数和单株粒数间接作用的影响。
Fourteen soybean cultivars were used as experimental materials to analyze the heritability and path of seven quantitative traits. The results showed that the direct selection of grain weight per plant was better; the heritability of plant height and grain weight per plant weight was smaller, but the direct effect on plant grain weight was the largest, Number and number of grain per unit of indirect effect.
