The genetic relationship of 31 peach\|blossom relatives and cultivars was studied by means of numerical taxonomic method. According to the Q cluster, the genetic relationship between peach\|blossom cultivars and \%Prunus ferganensis \%was very close; The relationship among the cultivars of dense\|compact peach group was closer, so was the cultivars of pendulous\|stem peach group and purple\|leaf peach group. The independence of the 23 characters was presented by R cluster. Based on the Q and R cluster analysis, the establishment of management information system of peach\|blossom cultivars was discussed.
