  • Seven economic characters of 41 selected individuals of Castanea henryi were analyzed with principal component analysis (PCA). Two overall indexes used to evaluate the individual characters were determined and the weighted value of overall index was taken as the criterion of individual ordination and classification. The authors suggested to reselect the clones among individual with large sized nut and medium sized nut, and attention should be paid on the examining the individuals of small sized nut with fine and special characters.
