大豆品种若干数量性状与产量的相互关系,已有许多研究。大多认为影响产量的主要性状是株高、主茎节数、有效分枝、每株荚数、单株粒数和百粒重。本文通过对江苏省淮北地区夏大豆品种产量构成因素的遗传相关和通径分析,研究如何进一步提高大豆单株产量,为选育高产类型的夏大豆品种提供参考。 Soybean varieties of quantitative traits and the relationship between yield, there have been many studies. Most of the main characters that affect yield are plant height, number of main stems, effective branches, pods per plant, grains per plant, and 100-grain weight. Based on the genetic correlation and path analysis of the yield components of summer soybean in Huaibei area of ​​Jiangsu Province, this paper studied how to further improve the yield per plant of soybean so as to provide references for the selection of high-yielding summer soybean varieties.
