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.
