摘要:
为了对麻核桃品种的性状进行选择和评价，以7个麻核桃品种的坚果为试材，对其纵径、横径、侧径、果形指数、三径均值和单果重进行了变异系数和主成分分析。结果表明：以性状的累积方差贡献率为85%以上，确定了2个反映麻核桃坚果主要性状的主成分，Y1方差贡献率为69.411，Y2方差贡献率为30.024；Y1主要反映坚果大小，‘大官帽’的Y1值最高为8.5，其次为‘满天星’和‘四座楼’，分别为0.71和0.54. Y2主要反映坚果果形，‘承德官帽’的Y2值最高为2.35，其次为‘满天星’和‘山西官帽’，分别为1.41和1. 13。
Abstract:
In order to provide a theoretical basis for selecting merit cultivars of Juglans hopeiensis Hu.The main economic characters were determined by principal component analysis，which included nut length，nut width，nut side diameter，fruit shape index，mean diameter and average nut weight. And 7 cultivars of Juglans hopeiensis Hu were used as materials. The results showed that，according to more than 85% of the cumulative variance proportion，the results proposed two principal components and their function equations which reflected the main nut characters of J.hopeiensis Hu，the variance proportions of Y1 and Y2 were 69.411 and 30024. Y1 mainly reflected the nut size，the principal component values(Y1) of ‘Da Guanmao’ was the highest 8.5，the higher were‘Mantian Xing’and‘Sizuo Lou’，their principal component values(Y1) were 0.71 and 0.54；Y2mainly reflected the nut shape，the principal component values(Y2) of ‘Chengde Guanmao’ was the highest 2.35，the higher were‘Mantian Xing’and‘Shanxi Guanmao’，their principal component values(Y2) were 1.41 and 1.13.
