Conteúdo: | Full-sib progenies were evaluated with the objective of comparing the performance of selected individuals in progenies tests with their clones in clonal tests. The experiments were carried out in randomized complete block design with five replications, five plants per plot, spaced at 3 m x 3 m, and four controls. The wood volume of each tree was determined after four years of growth. The 173 selected trees in the progeny test were used in the clonal tests in two different locations. The same experimental design was used with 20 replications, one tree plot, spaced at 3.5 m x 2.15 m with a border, and 13 controls (commercial clones). The growth traits of each tree were determined after two years of planting. Genetic parameters were estimated using general linear models. Realized heritability was greater than 80% indicating that the selection of trees in the progeny test was efficient.
