| 摘 要： | 与大豆产量相关的各生育性状中,生育期、株高、分枝、主茎节数、单株荚数、百粒重等都与产量性状呈正相关,其中相关分析表明,分枝、单株荚数与产量的正相关系数分别为0.545,0.488,达到了显著水平,生育性状与产量的通径分析表明,分枝数、单株荚数对产量的直接效应较大,与相关分析的结果一致.

| Abstract: | Growing period,plant height,branch number,nodes of main stem,pods per plant and 100-seeds weight are positive correlation with yield, correlation analysis showed that the correlative coefficient of branch number and pods per plant is 0.545 and 0.488,leads to significance level. path analysis on breeding traits with yield showed that branch number and pods per plant showed direct more positive effect, the result is same to the result of correlation analysis. |
