S.  aMorphological and molecular characteristics do not confirm popular classification of the Brazil nut tree in Acre, Brazil.h[electronic resource]  c2013  aIn the State of Acre, the Brazil nut tree, Bertholletia excelsa (Lecythidaceae), is classified by the local population into two types according to morphological characteristics, including color and quality of wood, shape of the trunk and crown, and fruit production. We examined thereliability of this classification by comparing morphological and molecular data of four populations of Brazil nut trees from Vale do Rio Acre in the Brazilian Amazon. For the morphological analysis, we evaluated qualitative and quantitative information of the trees, fruits, and seeds. The molecular analysis was performed using RAPD and ISSR markers, with cluster analysis. Significant differences were found between the two types of Brazil nut trees for the characters diameter at breast height, fruit yield, fruit size,and number of seeds per fruit. Despite the significant correlation between the morphological characteristics and the popular classification, we observed all possible combinations of morphological characteristics in both types of Brazil nut trees. In some individuals, the classification did not correspond to any of the characteristics. The results obtained with molecular markers showed that the two locally classified types of Brazil nut trees did not differ genetically, indicating that there is no consistent separation between them.  aBrazil nuts  aGenetic markers  aPlant breeding  aTropical wood  aBertholletia excelsa  aCastanha do pará  aEssência florestal  aMarcador genético  aMelhoramento genético vegetal  aMorfologia vegetal  aAcre  aAmazonia Occidental  aAmazônia Ocidental  aCastanheira  aClassificação morfológica  aEpitaciolândia (AC)  aFazenda Nova Jerusalém  aFitomejoramiento  aMadera tropical  aMarcador ISSR  aMarcador RAPD  aMarcadores genéticos  aMarcadores moleculares  aNuez del Brasil  aPlácido de Castro (AC)  aRESEX Chico Mendes  aSenador Guiomard (AC)  aSeringal Filipinas  aSeringal Petrolina  aWestern Amazon1 aFERNANDES, E.
