Abstract
Six promising eucalypt species, suitable for fiber or biomass production, have been identified with some confidence:
Eucalyptus camaldulensis,
E.
dalrympleana,
E. viminalis,
E. nitens,
E. globulus, and
E. grandis. The Forest Service's Institute of Forest Genetics has established provenance or seed source tests of
E. camaldulensis,
E. grandis,
E. nitens, and the
E. dalrympleana-
E. viminalis complex. In
E. camaldulensis, the Lake Albacutya source is outstandingly superior to any other, and can probably double yields previously achieved with this species in California. Growth among
E. grandis provenances is more uniform, but gains of 32 percent may be made by seed source selection. Tests of other species are too young for firm conclusions. Once superior seed sources are identified, they should be used to fill planting demands in California. The next step is to begin selection and breeding within the most productive species.
