The objective of this study was to evaluate the effect of the productivity of 15 eucalypt hybrid clones grow at four sites with different precipitation regimes on wood basic density and kraft pulping yield. The results obtained showed significant differences in annual growth increments among sites. Correlation between productivity and wood basic density was low for the genetic aspect and high for environmental aspect. It was also detected lower pulping yields and higher values of wood density for clones planted in lower productivity site. Differing from other studies found in the literature, the alkali charge for pulping did not show significant correlation with pulping yield.
