以河南省 1 0个大豆主栽品种为材料 ,对与株粒重有关的 1 1个性状的遗传分析结果表明 :株高、每节粒重、株有效荚数、粒茎比与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 ;各性状对株粒重的贡献大小依次为每节粒重、株有效荚数与粒茎比。因此 ,提高节粒重、株有效荚数与粒茎比是河南省大豆高产育种的主攻方向
The genetic analysis of 11 traits related to grain weight of 10 soybean cultivars in Henan Province showed that plant height, grain weight per plant, effective pods, stalk ratio and grain weight per plant Which was highly positive correlated with the environment less. The heritability of plant height to grain-stem ratio was larger, the heritability of each grain number per grain weight was smaller, and the contribution of each trait to grain weight was Section grain weight, effective pods and grain-stem ratio. Therefore, to improve the grain weight, plant effective pods and grain-stem ratio is the main direction of high yielding soybean breeding in Henan Province
