dc.descriptionTo better understand the genetic diversity of the cultivated upland cotton (Gossypium hirsutum L.) and its structure at the molecular level, microsatellite markers were used. The objective of this study was to evaluate genetic diversity and population structure in tetraploid cotton (Gossypium hirsutum L. race latifolium H.). Twenty cultivars and inbred lines from Embrapa Cotton Breeding Program, Brazil, were analyzed. From a total of 33 microsatellite (SSR) markers, twenty seven markers revealed 91 polymorphic SSR alleles. Two sub-populations were identified applying different methods (The Bayesian analysis, Principal Coordinates Analysis and Neighbor Joining Tree). Most of the cultivars belongs to Embrapa Cotton Breeding Program were allocated in sub-population I. The FST index indicated moderate genetic variability among the studied cultivars. In general, Embrapa cotton cultivars were the most dissimilar to GIBANGA and IMA CD05-8221 cultivars. The dissimilarity index ranged from 0.13 to 0.73 and the lowest genetic divergence was observed between BRS PRECOCE and BRS 286 genotypes. Combination of Embrapa cotton cultivars, GIBANGA and IMA CD-05 8221 is recommended for obtaining superior segregation in order to improve yield.pt_BR
