| 摘 要： | 对滇东北地区的134株初选核桃优树坚果的主要性状离散程度进行分析，结果表明，各优树间差异较大；对其中30株较优树的7个主要指标，即粗蛋白含量、粗脂肪含量、三径均值、单果质量、仁质量、壳厚及出仁率进行主成分分析，发现坚果质量、仁质量、蛋白含量及坚果大小4个综合指标的方差累计贡献率达89．315％，建立4个主成分函数；通过各优树的主成分分值结合其方差贡献率进行综合评分。评选出最优的10个单株．与坚果实际表现相符。

| Abstract: | The discrete degree of the main characters of nuts yielded from 134 walnut plus trees preliminarily selected from the northeast part of Yunnan Province was analyzed.It was showed that there were great differences in the 7 major criteria of the nut among the 30 reselected walnut plus trees,i.e.,the content of crude protein,content of crude fat,the mean value of three diameters,single fruit weight,nut kernel weight,shell thickness and the kernel ratio.The Principal Component Analysis with the 7 major criteria... |
