Abstract

Goal was to estimate genetic variability, genetic parameters and gains, as well as germination rate
on teca parent trees. Seeds were collected from Cachoeiro de Itapemirim (ES) county. The trial was carried
out in the Espírito Santo Federal University. Experimental design was randomized blocks with 60 treatments,
5 repetitions each and 19 plants per plot. Demonstrated genetic variability, individual heritability and parent
trees mean suggest great likelihood of genetic gain at more advanced ages. The 41, 11, 43 and 37 parent trees
presented larger genetic gains associated with increase on rate and germination percentages.
