Pesquisa Agropecuária Brasileira, Brasília, v. 40, n.10, p. 975-980, Oct. 2005.0100-204X0e- 1678-3921http://repositorio.bc.ufg.br/handle/ri/18661This study was carried out to assess the genetic variability of ten “cagaita” tree (Eugenia dysenterica) populations in Southeastern Goiás. Fifty-four randomly amplified polymorphic DNA (RAPD) loci were used to characterize the population genetic variability, using the analysis of molecular variance (AMOVA). A φST value of 0.2703 was obtained, showing that 27.03% and 72.97% of the genetic variability is present among and within populations, respectively. The Pearson correlation coefficient (r) among the genetic distances matrix (1 – Jaccard similarity index) and the geographic distances were estimated, and a strong positive correlation was detected. Results suggest that these populations are differentiating through a stochastic process, with restricted and geographic distribution dependent gene flow.engAcesso AbertoMyrtaceaeCerradoTropical speciesGenetic diversityMyrtaceaeEspécies tropicaisDiversidade genéticaEugenia dysentericaArtigo10.1590/S0100-204X2005001000005
