图3 巢式杂交群体荚果的6个表型性状的频率分布?相关性和拟合曲线 A、B、C、D、E分别表示巢式杂交群体中的组合YZ9102×YH15、ZH6×YH15、YH15×YY20、YH15×FHS、YH15×NC94022。图中的上三角形显示了2个籽仁性状之间的相关系数以及显著性水平,其中,*：P<0.05,**：P<0.01,***：P<0.001;下三角形用散点图显示2个籽仁性状之间拟合度。对角线是6个籽仁性状的直方图

Fig. 3 Frequency distribution, correlation and fit curve of six phenotypic characters in nested-crossing population A, B, C, D, and E represent YZ9102×YH15, ZH6×YH15, YH15×YY20, YH15×FHS and YH15×NC94022 combinations in nested-crossing population, respectively. The upper triangle in the figure shows the correlation coefficient and significance level between the two kernel traits. Where, *:P<0.05, **:P<0.01, ***:P<0.001; the lower triangle shows the fitness between the two kernels traits with scatter plots. Diagonal is a histogram of the six kernels traits
