In 1993 Hancock Victorian Plantations planted a large Eucalyptus smithii provenance-progeny trial at Kelly's leasehold near Stockdale in Victoria. The trial was established to test for superior families and individuals, with the intention of converting the trial to a seed orchard. In 2008 seedEnergy took over management of the trial and has continued to develop it as a seedling seed orchard.
The trial comprises 136 open-pollinated families from 4 localities in NSW and Victoria tested in comparison with 2 bulked seedlots from a range of NSW localities.
At age 14 years all trees in the trial were assessed for diameter, stem form, branch form and number of stems. A genetic evaluation was carried out by Dr Jo Sasse in May, 2008. The trial analysis revealed significant differences in growth between provenances and families, and between provenances for branch form. The trial was converted into a seed orchard in 2010 by selective thinning to retain the best trees for seed production.
Eucalyptus smithii seed became available from the seed orchard in 2009.
