| Abstract: | By using principal component analysis, the paper focuses on the analysis of ten species (cultivars) of the fruit characters of waxberry wild in Yunnan and cultivated from other areas. The results showed that the cumulative contribute rate of the foregoing three species (cultivars) amounts to 92.5% and six species with the better -synthesized characters are selected according to the worth of the principal components as well. It also provides the referential value for exploitation and utilization of the wild waxberry resources. |
