摘要：The interest by assai palms fruits in other regions of the country makes necessary genetic improvement for the Euterpe oleracea . The research aimed to verify, by gge (Genotype main effects + Genotype-by-environment interaction) biplot, those promising for selection among 30 families from different mother plants of a population of the municipality of Anajás and cultivated in Tomé-Açu, Pará, and also identify the environment that best allows the discrimination of these. The experimental design was in randomized blocks, with 30 treatments (progenies) and three repetitions, were evaluated the characteristics: average weight of the bunches (pmc), in grams; total number of clusters (ntc) and; total weight of the bunches (ptc). It was concluded that for purposes of selection based on the ideotype, the best genotypes in pmc were G22 and G19; in ptc are G10 and G14, and ntc was the genotype G10; the genotypes with average values for the evaluated characteristics showed less stability, except G10 for ptc; The gge biplots allow you to view the layout, the inter-relationship with environmental effects and choose superior genotypes; in the graphical analysis by gge biplot method the environments effects (years) allow differentiation of genotypes, with emphasis to the environment A3 for pmc and ptc, and A1 For ntc; for the representativity of all environments is the A1 on the characteristics pmc and ptc; while that is the A2 for ntc.
