A study on phenotypic diversities in the natural population of Rosa banksiae Ait. in Yunnan

15 phenotypic characters of Rosa banksiae from five natural populations in Yunnan were analyzed applying the population biological theories and methods.The results showed that variation was widely distributed among and intra-populations,Fvalue of the 15 characters were from 1.92 to 370.6,and most traits were quite significantly or significantly diversified both among and within populations;The mean phenotypic differentiation coefficient of the 15 characters was 61.10%,and the variation among populations was higher,which indicated that the variation among populations was the main source of the phenotypic variation;The Correlation analysis showed that most characters were affected by different latitudes;Five natural populations was arranged into 2 groups by UPGMAcluster analysis.
