Abstract:

Taking 22 pepper cultivars as materials,eleven botanical characters were investigated,and clustering analysis were applied.The results showed that the coefficient of variation (CV) of 11 traits were 13.75% to 138.12%,the maximum CV was single fruit weight,the minimum was stem diameter.The genetic distance of 22 pepper cultivars was 1.036¡«7.618,all cultivars were clustered into four groups,the first group include 11 species,the second group include 8 species,¡®No 8¡¯with a distant relationship with other species,singly clustered into the third group,the fourth group only contain two species.
