To characterize morphologically accesses of sweet potato from the germplasm collection of the Universidade Estadual do Norte Fluminense (UENF) Brazil, as a way to optimize the utilization of important genomes for plant breeding, two experiments were carried out in field conditions, both in a randomized blocks design with three replications. The experiments were done in November at UENF and December in Campos. For such experiment, fourteen sweet potato accesses were evaluated for different traits related to aerial parts, and root descriptors, in a total of twenty characteristics. Genetic variability between accesses was observed, mainly due to characteristics of pubescence of the stem apex, pigmentation of the inferior veins of leaves and shape of roots. The accesses, Amarelinha, Roxinha, WON-B and Campina 3 presented interesting characteristics for the market of north-fluminense region.
