Açaí (Euterpe oleracea Mart.) - a common tropical palm has high social, economic, and environmental importance in the Amazon region. In light of increasing exploration to obtain fruit heart this palms, comprehensive studies are warranted for conservation genetic improvement. Here, we characterized açaí accessions using phenological, morphological, agronomic descriptors random amplified polymorphic DNA (RAPD) molecular markers joint selection with greater productivity. Hundred were analyzed 18 morphoagronomic 13 RAPD markers. The spathe inflorescence emission phases during flowering fruiting showed seasonality. Based on coefficient variation mean squared error, exhibited variability tested distributed into seven groups. Fruit, seed, pulp weights important distinction identification those presented >85% similarity, 85 accessions, nine subgroups, could not be differentiated There was no correlation between grouping based morphometric Panicle weight 3.9-9.0 kg 15 100-fruit 35-50 g six accessions. Therefore, productivity selected.
