Knowledge of germplasm diversity and its genetic characterization is crucial to crop improvement and conservation strategies. This study aimed at characterization of diversity genetic and population structure of traditional sweet cassava germplasm at the molecular level. A total of 60 sweet cassava accessions from Campo Grande city, Mato Grosso do Sul State, Brazil, and a commercial variety, were analyzed using microsatellite markers. Allelic frequencies were used in order to assess the genetic diversity indexes for each marker. Population structure was analyzed using genetic distances and Bayesian model. A total of 88 alleles were identified from the 19 SSR markers, with an average of 4.63 alleles per marker. The mean of polymorphic information content (PIC) was 0.525 and indicated that the markers used were informative and polymorphic, especially the marker SSRY 13. The heterozygosity observed (Ho) ranged from 0.569 to 0.984, with a mean of 0.862, evidencing the existence of high natural heterozygosis in cassava. The genetic diversity mean was of 0.601 and revealed considerable genetic diversity among the genotypes. Population structure analysis resulted in the distribution of the 61 accessions in two distinct sub-populations, by Bayesian analysis, Neighbor-Joining Tree and Principal Coordinates Analysis, indicating the existence of significant genetic diversity between sub-populations. Combination of cassava accessions BGM 570 × BGM 613 and BGM 570 × IAC 576/70 is recommended for obtaining superior segregation in order to improve yield. The results will contribute to the conservation of the Mato Grosso do Sul germplasm and sweet cassava breeding.
