Cluster analysis based on the genotype values of ten traits of thirty-one pepper inbred lines were studied by UPGMA and Steuclid genetic distances calculation methods. In the cluster analysis based on Steuclid genetic distances calculation, C. annuum var. longum and C. annuum var. grossum were divided at GD6.0; At GD4.6, thirty-one pepper inbred lines were classified into five groups: group Ⅰincluding No. 7 only which belong to bell pepper; group Ⅱincluding No. 9 and No. 5 with high-plants, late-maturing, and susceptibility to disease; groupⅢincluding No.25 inbred line, which possessed mid-resistance, low plant height, and early-maturing; group Ⅳ including No. 6, 12, 10, 19, 14, 11, 29, 31, 30, 24, 16, 20, 18, 17, 21, 15, 13, 23, 22, 8, 4, which was medium in traits including maturity and resistance, which was different in plant height; groupⅤincluding No. 27, 26, 28, 3, 2, 1, which had high plant and late maturing and better resistance. These results are beneficial for us to elect parents of hybrid
