SUMMARY The growth and survival of Eucalyptus obliqua seedlings from twenty‐two provenances throughout the range of the species in south‐eastern Australia were studied in three field trials in Tasmania and Victoria. Early results indicated significant variation among provenances for several growth parameters and for survival. Ranking for height was consistent on the two low‐altitude planting sites and similar to that in previously reported glasshouse studies. Within provenances there were also significant differences between families for growth and survival. These results suggest that genetic improvement of the species is possible, not only by selection of the most suitable provenances for particular sites, but also by the selection of superior individual trees within a provenance.
