Summary

Open-pollinated seedling progenies of Eucalyptus obliqua grown in a uniform environment showed evidence of genetic variation among geographically different localities and among parent trees within localities. Locality variation did not appear habitat-correlated, so no predictor of a superior locality for tree-improvement purposes could be suggested, other than appearance of the trees; breeding strategy should include tree selection within localities. Several superior localities were indicated consistently but many showed marked fluctuations, suggesting the need for caution in interpreting seedling data.
