Twenty-nine rice cultivars belonging to EMBRAPA Arroz e Feijão germplasm bank in Brazil were genotyped by 24 SSR markers to establish their structure and genetic discrimination. It was demonstrated that the analyzed germplasm of rice presents an expressive and significant genetic diversity with low heterogeneity among the cultivars. All 29 cultivars were differentiated genetically, and were organized into two groups related to their upland and irrigated cultivation systems. These groups showed a high genetic differentiation, with greater diversity within the group that includes the cultivars for irrigated system. The genotyping data of these cultivars, with the morphological e phenotypical data, are valuable information to be used by rice breeding programs to develop new improved cultivars.  aGenetic resources  aGenetic variation  aIrrigation  aMicrosatellite repeats  aRice  aArroz  aBanco de germoplasma  aIrrigação  aMarcador molecular  aOryza sativa  aRecurso genético  aVariação genética  aCultivar discrimination  aGenetic diversity  aMolecular marker1 aBRONDANI, C.1 aHOFFMANN, L.
