Caracteriza？？o fenotípica e genotípica de progênies de Euterpe oleracea coletados no Afuá-Pará nas condi？？es do Amapá

the assai tree fruits (euterpe oleracea) is one of the main food sources in the states of pará and amapá, generating consumer interest in other regions and countries. in this research were evaluated 75 progenies collected from different populations derived from afuá, pará, cultivating an mazag？o experimental field in amapa state, in relation to vegetative characters that can result in better plant development and reflect on larger yield. the experimental design adopted was randomized blocks with two replications. the results indicate that there are differences among the progeny for the amount of shoots to reach maturity is a natural process in which these differences become less pronounced in adult plants, indicating greater variability in the young than in adult plants; the relationship cvg/cve and the heritability values show that the selection may be difficult; the correlations confirm that should be developed and implementd the management of stems (sprouts shoots) due to the tendency of these negative effects on other traits; the estimated phenotypic, genotypic and residural correlations show that environmental factors contribute to the variability of the species and cluster analysis allowed the formation of dissimilar groups useful for guiding future crosses.
