A total of 247 accessions of sugar beet were collected from 12 countries and 26 traits including 16 descriptive and 10 numerical characteristics were tested. The results indicated that In the descriptive characteristics, 16 descriptive properties had showed the genetic differences and the genetic diversity index ranged from 0.4806to 1.5230 with the average of 0.8608.The smallest and the largest diversity index values were observed in root nude and growth vigor, respectively. The coefficient of variation of 10 numeric characters was between 1.29% and 7.08% with the average of 3.57%, the content of a-N was the smallest and the number of leaves was the largest. The phenotypes of genetic differences were analyzed between different countries.Thecountries. The genetic diversity and CV of phenotypic traits showed a tendency of China>Netherlands>America>Sweden>Japan>Germany>Hungary>Poland>Russia> Denmark>France>Belgium.247 sugar beet varieties were divided into 5 groups by cluster analysis of phenotype traits at 7.5 genetic distances by software SPSS22.0. Every country showed difference in the proportion of all of the five classifications. 15 high-yield resources and 15 high sugar resources were screened out, which could be used as the parent material for improving yield and sugar content in breeding.
