以 10个广西夏大豆品种为材料研究株高、主茎节数、分枝数、单株荚数、单株粒数、每荚粒数、百粒重 7个性状间相关及其对单株产量的效应。单株粒数与单株产量呈极显著正相关 ,对单株产量的直接效应及总贡献最大 ;单株荚数与单株产量亦呈极显著正相关 ,对单株产量的总贡献仅次于单株粒数 ;单株产量与主茎节数呈显著正相关 ,与每荚粒数、株高相关不显著 ,与分枝数呈弱正相关 ,与百粒重呈弱负相关
A total of 10 Guangxi summer soybean cultivars were used to study the correlation among plant height, number of main stems, branches, pods per plant, grains per plant, grains per pod, Effect of yield. The grain number per plant was significantly and positively correlated with the yield per plant, and the direct effect on the yield per plant and the total contribution were the most. The pods per plant were also significantly and positively correlated with the yield per plant, There was a significant positive correlation between yield per plant and the number of main stems per plant, no significant correlation with grain number per plant, plant height, weakly positive correlation with branch number, and weak negative correlation with grain weight
