| 摘 要： | 2009年通过对云南省油茶的主产区文山州富宁县复选的139株油茶单株的果实三径均值、果形系数、平均单果重、平均单果籽实重、平均单果果皮重、鲜果出籽率、冠幅单位面积鲜果产量、冠幅单位面积鲜籽产量、出仁率等17个指标进行调查,对其变量因子进行平均正交旋转后确定主成分因子,对主成分因子选取果实三径均值、果形系数、平均单果重、鲜果出籽率、冠幅单位面积鲜籽产量、出仁率建立回归方程Y=0.358X1+3.695X2+0.064X3+0.05X6+0.388X8+0.022X9-10.616。依据回归方程计算综合评分值,结合含油率指标,确定优树选择指标,采用聚类分析,选取了32#、111#、113#、123#、121#、31#、25#、39#、110#、5#、58#相对样本群体具有明显增益的11株优良单株,并对其各项指标做出了综合分析。分析结果对云南省油茶良种的多指标综合选育具有一定的参考价值。
