以安阳市农业科学院培育的新品系为材料,应用灰色关联度分析方法,对大豆的主要性状进行了分析。结果表明:大豆主要性状对产量的影响以百粒重最大,其后依次为株高、有效分枝、单株粒重、单株粒数、单株荚数、主茎节数、底荚高度。百粒重是产量的主要影响因素,因此,在品种选育中,要优先考虑选择籽粒大、株高、结荚相对较多的单株。
With the new line cultivated by Anyang Academy of Agricultural Sciences as the material, the main characters of soybean were analyzed by using gray relational analysis method. The results showed that the effect of main characters of soybean was the highest on the yield, followed by the height of plant, the effective branch, the weight of plant per plant, the number of plant per plant, the number of main plant, the number of main stem, . One hundred kernel weight is the main factor affecting the yield. Therefore, we should give priority to the selection of individual plants with large grain size, plant height and podding.
