Conteúdo: 	Heritabilities and expected selection gains were estimated in nine provenances of Mimosa scabrella Bentham by means of random and mixed reproduction models. In the random model, the relationship coefficient was considered as half-sibs, and in the mixed, relatedness was estimated based on parameters of the mating system. The trait height was measured six months after planting in the field and a progeny sample of each provenance was analysed by isoenzyme electrophoresis to estimate parameters of the mating system. The mean inbreeding coefficient was 0.392, which is 56.8% higher than expected in half-sib progenies (0.25). The mean estimates of the additive genetic variance, heritability within progenies and gains expected with selection among and within progenies, calculated by the underlying random reproduction model were overestimated, respectively, by 36%, 48% and 41%, when compared to estimates obtained based on the mixed reproduction model..
