The açai fruit has its consumption in expansion in Brazil and abroad, being used descriptors in quantity that hinders the evaluation in the field and the selection, being that the multivariate analysis would facilitate this process, therefore the objective of this work was to analyze the behavior of the characteristics aiming to determine which have greater contribution in phenotypic manifestations and also those with greater potential to be used for selection. The experimental design adopted was randomized blocks with two replications, five plants per plot and 175 progenies. The evaluated characteristics were: Foliar release (FLF); Mature leaves opened (FAB); Senescent leaves (FSE); Number of machetes or espatas Issued (FC); Bunch with inflorescence in flowering (FL); Green bunch Formation (FV); Bunches with green fruit formation (FF); Bunch with ripe fruits (FM); Bunch size (TM); number of tillers present in the stipe (NE); number of bunches without fruit (VS). The conclusions obtained were that the initial analysis indicates the use of two characteristics for selection (FAB and another among the others); when expanding the number of characteristics by the dendrogram must be used FAB, choose NE or TM and choose one among the others; Biplot refined the choice of characteristics, allowing to select FAB, TM, FV and FF, with positive contributions; the use of combined methodologies, mainly with Biplot, allows to correct errors in the choice of characteristics within a wide range of characteristics for use in selection.
