Abstract:
73 germplasm resources of Akebia trifoliata from China were collected, 16 biological characters had been measured, Anova and the analysis of principal component(PCA) were also been done by SPSS, every germplasm resource was classified by cluster analysis. The results showed that there are most significant differences in every index of fruit, and the differences of fruit were biggest in germplasm resources. According to PCA, the 16 biological characters were summed up in four main characters: fruit factor, leaf factor, seed factor and pulp factor, and 73 germplasm resources were divided into five types according to the cluster analysis. All of which offered the important morphological foundation for the collection and the choice of excellent germplasm of Akebia trifoliata.
