Abstract:: Twenty-three introduced and breeding germplasm resources for purple sweetpotato in Guizhou were used as test materials.Genetic diversity among the materials was studied by cluster analysis of morphologic characteristic in order to provide theoretical guidance for new varieties breeding of purple sweetpotato.The results showed euclidian distance for ‘13-24-2’ and ‘13-24-7’ was 0.25，which was the nearest；the farthest euclidian distance was 5.62 for ‘13-4-2’ and ‘13-24-2’.The 23 Guizhou purple sweetpotato varieties could be classified to three groups，the first class included 16 germplasms；the second class included 6 germplasms；the third class only included one germplasm.
