Principal component analysis of ornamental traits in Camellia chekiangoleosa

Ten ornamental characters of 132 Camellia Chekiangoleosas,which were preliminarily selected from Lishui,Zhejiang province,were analyzed by principle component analysis for comprehensive ornamental evaluation of the trees.The results showed that 84.923% information of ten ornamental characters could be condensed into five principle components.The model of ornamental evaluation was established by the contribution proportion of five principal components as the weight coefficient and eigenvectors of correlation matrix of ornamental traits in Camellia chekiangoleosa.Thirty-five superior trees were finally screened out,with the results similar to the actual performance of practical phenotype.
