Abstract
Clonal forestry is the approach used for deployment of Pinus elliottii × P. caribaea hybrids in Queensland, Australia. Clonal forestry relies on the ability to maintain juvenility of stock plants while selections are made in field tests, so that genetic gains are not eroded by the effects of stock plant maturation. Two parallel approaches are employed in Queensland to maintain juvenility of clonal material. Firstly, the ortet and several ramets of each clone are maintained as archive hedges less than 20-cm height for the duration of field tests. Secondly, shoots from archive hedges are stored in tissue culture at low temperature and low irradiance to slow growth and slow maturation. Once the best clones have been identified, production hedges are derived from both archive hedges and tissue culture shoots. About 6 million rooted cuttings are produced annually, representing almost the entire planting program of Pinus in subtropical Queensland.
