Conteúdo: 	The objective of this study was to evaluate the genotype x environment
interaction and to estimate the genetic components of variance and mean using
mixed models in early selection of 238 clones of Pinus taeda propagated by
somatic embryogenesis. 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.
