Sweet potato accesses from the germplasm bank of the Universidade Federal dos Vales do Jequitinhonha e Mucuri, Diamantina, Minas Gerais state, Brazil were characterized. The experiment was carried out between February and November 2006, using a randomized blocks design, with 65 treatments and three replications, totaling 195 plots. The evaluation of the vegetative part was carried out three months after planting and the roots were harvested nine months after planting. Based on the dendrogram of morphologic differences we observed a great morphologic variability on the accesses. The characteristics of the vegetative part showed significant differences among the clones, by Scott Knot test at 5% probability, differently from those of the roots.
