Abstract

This study had as aim verifying the occurrence and distribution of genetic and fenotipic variation among tested populations of baru plants (Dipteryx alata vog.) Thus an assay was carried out with 150 plants from three regions of Goiás State. It had 50 plants per region, and it were randomizes choiced at 1995. Seeds and plantets were analysed about germination and emergency and initial development characters. The experiment was planted as hierarchal model with regions level, plants within regions and fruits within plants. There was’nt variation about plant emersion percentage and emersion velocity index. There was variation about emersion velocity (days). Plant height and base diameter at 30 days after emersion showed variation at regions and plants within regions levels. The most variation proportion was founded at plants within regions level with high levels of transmission to all characters.
