以河南大豆为材料 ,用生物统计方法研究了株高、株有效荚数、节粒重、株茎重、粒茎比和每荚粒数等株粒重构成因素对产量的作用 .结果表明株高、节粒重、株有效荚数、粒茎比和株粒重呈正相关 ,环境相关较小 ,说明其间的关系主要受遗传因子控制 ,可以作为提高大豆产量的有效选择指标 .其对大豆产量的作用大小依次为节粒重、株有效荚数、粒茎比等、因此 ,在合理密植的条件下 ,提高株有效荚数和节粒重 ,适当增加粒茎比有利于豫大豆高产育种 .
The effects of plant height, number of effective pods, weight of section per plant, stem weight, stalk ratio and grain number per pod on the yield were studied by using biostatistics method with soybean in Henan province.The results showed that strain The results showed that there was a positive correlation between the number of pods, the number of pods per plant, the number of pods per plant, the ratio of grain stem to grain weight and the grain weight per plant, indicating that the relationship between them was mainly controlled by genetic factors and could be used as an effective selection index for increasing soybean yield. The effective pod number, stalk ratio and so on. Therefore, under the conditions of close planting density, the effective pod number and grain weight were increased, and the proper proportion of grain stem to stem increased the breeding of high yielding soybean.
