Abstract: 18 phenotypic traits of 13 Miscanthus sinensis nature populations origin from Guangxi province were measured in this paper. Analysis of variance for all traits showed that there were significant differences among and within populations. The result indicated that Miscanthus sinensis was abundant in genetic diversity. The average of phenotypic differentiation coefficient (Vst) of 18 phenotypic traits was 32.05% with the range from 17.99% to 47.21% and the Vst of leaf, stem, panicle and spikelet were 38.01%, 29.08%, 32.84% and 27.14%, respectively.13 natural populations of M. sinensis in Guangxi province could be divided into 4 groups by UPGMA cluster analysis which indicated that M. sinensis varieties were uncomformity with its geographic origin. The correlation analysis between phenotypic traits and ecological factor showed the some traits have significant or extremely significant correlation with ecological factor. These result offered the basic data for further study of conservation and genetic breeding of Miscanthus.
