Genetic parameters for survival and diameter were estimated from measurements from 4 to 5 year old progeny trials of Eucalyptus globulus ssp. globulus in Australia and Portugal. The trials comprised over 660 open-pollinated families, covering the natural range of species. Individual narrow sense heritabilities for survival were moderate to high (average h(op)(2) = 0.31). Correlations between survival at different sites were also moderate to high ranging from 0.16 to 0.92 (average of 0.48), suggesting that in some instances survival ability can be determined by different genes. Diameter and survival were also positively correlated within sites (average r(g) = 0.54).
