Sweet cassava is a food culture of great importance because it is a source of nutrition and energy for
millions of people in tropical and sub-tropical regions. For that reason, genetic diversity and population
structure studies are necessary in order to obtain more information regarding the evaluated genotypes,
reassuring their use in future breeding programs. The objective of this study was to evaluate the
genetic diversity and population structure of 51 traditional sweet cassava accessions collected in the
Southern of Minas Gerais State, Brazil, using 20 microsatellite markers. All markers used to genotype
the 51 sweet cassava accessions were polymorphic (PIC = 0.4080). Four sub-populations were
identified using different methods (Bayesian analysis and multivariate analysis). The PhiPT (analogous
Wright Fst) index of 0.073 indicated a moderated genetic variability among the studied traditional sweet
cassava accessions. The dissimilarity index ranged from 0.097 to 0.560. Among the most divergent
accessions stands out BGM 690, BGM 655 and BGM 660, which are the most recommended for
obtaining a heterosis in order to increase yield production. |

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.
