摘　　要：运用主成分分析和聚类分析法对杂交榛的10个经济性状进行多元分析,对其前3个主成分的得分值进行聚类,将20个品系分为三类:第一类为果实品质佳且较丰产的品系,包括3#、7#、26#、20#、15#等;第二类包括5#、13#、10#、22#、23#等,具较强的丰产性和早实性;第三类为9#和10#品种(系),果大、壳厚、丰产性较差。考虑到经济效益,可优先选择一、二类品系为扩大生产之用,而第三类可考虑作为授粉树。Ten economic traits of hybrid hazel were analyzed principal component analysis and cluster analysis, three principal components of the cluster scores as the standard classification, 20 clones were divided into three categories： the first category is the fruit of good quality and relatively high yield clones, it including 3# , 7 # , 26 # , 20# and 15 # , etc; the second category includes 5# , 13# , 10# , 22# and 23# , these clones have performance of high yield and early solid, especially 13# outstanding; the third category including 9# and 10# clones, fruit is large but shell is thick. Take economic benefits into account, the first and the second category clones can be used for expanding production, while the third category can be considered as pollination tree.
