以10个河南夏大豆主栽品种为材料，对与株粒重有关的10个农艺性状进行了遗传相关、遗传参数和通径分析。试验结果表明：株高、每节粒重、株有效荚数、粒茎比和株粒重呈高度正相关，与环境相关较小；株高与粒茎比的遗传力较大，每荚粒数与每节粒重的遗传力较小；各性状对株粒重的重要贡献的大小依次为每节粒重、株有效荚数与粒茎比。因此，大力提高节粒重、株有效荚数与粒茎比是河南夏大豆高产育种的方向。
Ten major agronomic traits related to grain weight were used for the genetic correlation, genetic parameters and path analysis in 10 Henan summer soybean cultivars. The results showed that plant height, grain weight per plant, effective pods, stalk ratio and grain weight were highly positively correlated with the environment, and the heritability of plant height to grain-stem ratio was larger. The heritability of number and grain weight per section was small. The important contribution of each trait to grain weight was in the order of grain weight per plant, effective pods and stalk ratio. Therefore, vigorously improve the section weight, plant effective pods and grain-stem ratio is the direction of high yielding summer soybean in Henan.
