Abstract: An experiment was conducted to analyze the phenotypic diversities in terms of 6 phenotypic traits（height of plant ,length of petal, number of leaf, number of flowers, length of leaf and width of leaf）using 7 natural populations of Lilium regale Wilson. Analysis of variance for all traits showed that there was significant difference among populations. Among populations, the F value of 6 traits was from 4.878 to 34.915, except leaf was significantly different; other traits were quite significantly different. Within population other traits were not significant except that length and width of leaf. The mean phenotypic differentiation coefficient VST of the 6 traits is 61.5%, and the variation among populations was higher than within population, which indicated that the variance among populations was the main part of the phenotypic variation. The correlation analysis between the phenotypic traits of Lilium regale Wilson and geography factor showed that the correlation between them was not significant except that height of plant and the number of flowers and width of leaf significantly different positive affected by latitude.7 natural populations of Lilium regale Wilson could be divided into 2 groups by UPGMA cluster analysis. Explaining the phenotypic traits didn't gathers a type according to geography distance.
