利用黄淮地区５３个夏大豆品种（系）的７个主要农艺性状与单株产量的表型值资料进行简单相关分析和通径分析，结果表明，株高、主茎节数、单株荚数、单株粒数与单株产量呈极显著正相关，百粒重与单株产量呈显著正相关，底荚高和分枝数与单株产量呈不显著正相关。各农艺性状对单株产量的直接作用从大到小依次为单株粒数、百粒重、单株荚数、株高、分枝数、主茎节数、底荚高度。

Based on the simple correlation analysis and path analysis of seven main agronomic traits and phenotypic values ​​of 53 summer soybean varieties (lines) in Huang-Huai region, the results showed that the plant height, the number of main stems, There was a significant positive correlation between the number of grains per plant and the yield per plant. The grain weight per plant was positively correlated with the yield per plant. There was no significant positive correlation between the number of pods per plant and the number of branches per plant. The direct effect of each agronomic trait on the yield per plant was in order of grain weight per plant, weight per plant, number of pods per plant, plant height, number of branches, number of main stems and height of bottom pods.
