This work aimed at studying the genetic variability in young progenies of açaizeiro population. The experiment was installed in the physical base of Tomé-Açu of the Embrapa Eastern Amazônia, involving the study of 25 progenies of half sib delineated in látice 5 x 5. The experiment consisted of two repetitions and five plants per plot. Plant height (AP) and diameter (DFC), number of live leaves (NFV) and tillers (NP) were obtained twelve months after planting. The analyses of variance showed that, except plant height and number of leaves characteristics, it had significant differences 5 % of probability for diameter plant and number of tillers. Values estimated in the superior extremity of the interval of variation for the characteristic appraised point out promising individuals to be selected for producing fruits, regarding diameter of the plant, due to the fact that these characters are correlated positively. The biggest estimates of genetic parameters had been gotten in relation to the characteristic number of tillers, followed by plant diameter.
