Conteúdo: | In this work the genetic divergence among 14 sweet cassava cultivars was estimated by their morphological agronomic traits and RAPD molecular markers. The Tocher cluster analysis and the Nearest Neighbor Method were applied. The most dissimilar cultivars were Pão and Guaíra, Fécula Branca and Pão, and Pão and Caipira, while the most similar cultivar were the Fécula Branca and Branca 1, Branca 3 and Branca 1, and Guaíra and Branca 1. The Jaccard?s coefficient showed that the most similar cultivars were Guaíra and Quarenta Quilos, while the most dissimilar were Branca 3 and Amarela da Rama Cinza. The divergence analysis indicated that promising crosses could be made between the Branca 3 cultivar and the Pão, Amarela 1, Fécula Branca and Amarela 2 cultivars for the high genetic divergence, favorable agronomic and culinary traits, and disease resistance on the part of at least one of the parents involved in the cross.
