Abstract
This study aimed to evaluate the genetic dissimilarity among sweet potato genotypes using morphological and molecular descriptors. The experiment was conducted in the Olericulture Sector at Federal University of Jequitinhonha and Mucuri Valleys (UFVJM) and evaluated 60 sweet potato genotypes. For morphological characterization, 24 descriptors were used. For molecular characterization, 11 microsatellite primers specific for sweet potatoes were used, obtaining 210 polymorphic bands. Morphological and molecular diversity was obtained by dissimilarity matrices based on the coefficient of simple matching and the Jaccard index for morphological and molecular data, respectively. From these matrices, dendrograms were built. There is a large amount of genetic variability among sweet potato genotypes of the germplasm bank at UFVJM based on morphological and molecular characterizations. There was no duplicate suspicion or strong association between morphological and molecular analyses. Divergent accessions have been identified by molecular and morphological analyses, which can be used as parents in breeding programmes to produce progenies with high genetic variability.

Sixty sweet potato genotypes were assessed, which belong to the germplasm bank of UFVJM
Summary
Lam.) is a tuberous vegetable of economic and social importance, grown mainly by small farmers and used as a staple food for the world’s poorest regions (Roesler, Gomes, Moro, Kummer, & Cereda, 2008). Since it has high levels of carbohydrates, sugars, minerals, and vitamins A, C, and B complex, it can be used for multiple purposes. Vale do Jequitinhonha is among the poorest regions in Brazil. It is diversified and has a poorly developed agriculture due to an arid climate
