The experiment consisted of a complete blocks design, with 12 replications, with one plant per plot, in four environments, at 1, 3, and 4 years of age. Estimates of heritability and of genetic gains in the evaluated environments showed good prospects for selection of superior genotypes. The effect of genotype x environment interaction was pronounced for all traits investigated. With the simultaneous selection for stability and adaptability, 10% genetic gain was obtained in relation to the mean of the commercial controls. This estimated gain indicates that the somatic embryogenesis technique has been effective in propagation of clones with good productive potential.  aEarly selection  aMelhoramento Genético Vegetal  aPinus Taeda  aSeleção Genética  aClonal silviculture  aEspécie exótica  aForestry improvement  aGenetic selection  aSeleção precoce  aSilvicultura clonal1 aXAVIER, A.1 aRESENDE, M.
