Abstract

The objective of this work is to generate information about the distribution of the levels of genetic variability in two provenances of Euterpe oleracea. A sample of seeds of each individual from distinct regions had been collected at Curralinho and Limoeiro of Ajuru, localities of Pará State placed on the Estuary of Amazon river. The experiment was installed in randomized blocks with two replications and five plants per plot. Seedlings were evaluated, at 10 months of age for: height, diameter and number of leaves. Significant genetic variations between provenances for number of leaves were detected. Curralinho provenance presented greater genetic variability than Limoeiro do Ajuru. Small levels of coefficients of genetic variation among provenances shows that the strategy for collecting germplasm must be concentrated in few provenances,each one represented by a great number of individuals.
