  1. Tree Improvement and cuttings production of Oji Paper Co. Eucalyptus globulus at Albany Forestry Research Centre Nigel England

  2. Time points Oji Paper Co. • 1992 APFL planting began • 2001 Start of Phenotypic tree selection • 2003 Albany Forestry Research Centre opened • 2004 First field trial planted (2ha) • 2005 Trials and 10ha of cuttings planted • 2006 Trials and 80ha of cuttings planted • 2007 Planting of 100ha projected

  3. Phenotypic Tree Selection Oji Paper Co. • In plantations of 6-10 yrs • Immediate neighbours must be alive • Straight without forks • Measure surrounding 25 trees • DBH > plot mean+1.5sd

  4. Phenotypic Tree Selection Oji Paper Co. Example of typical phenotypic tree selection plot X X X Dead X X X Dead X X X X Candidate X X X Dead X Tree X X X Dead X X X X Dead X X X

  5. Wood sampling • Whole tree sample based on discs at 10, 30, 50, 70, and 90% of ht to 5cm DOB • Wood tested for: Basic density Pulp Yield Alkali consumption Fibre length • Cores also taken at BH • NIR analysis (with ENSIS)

  6. Propagation by cuttings from coppice Coppice in field Cuttings from coppice after 8 weeks (4 clones chosen at random)

  13. Clone trials Oji Paper Co. • STP, 5TP, and 72TP designs depending on plants available • 60 clones in trials of at least 8 plants • Range of sites tested within APFL planting limit of 120km of Albany • Improved seedling controls in all trials • Joint trials with other companies

  14. Clone trial results Oji Paper Co. 6.00 5.00 T12 4.00 T15 Height (m) T17 3.00 T33 Unimp seed 2.00 Imp Seed 1 Imp Seed 2 1.00 0.00 0 5 10 15 20 25 Data: 4 x 72 tree plots on Time from planting (months) 1 site

  15. Developing a breeding population • All clones are being planted in a Breeding Arboretum and being out-crossed • Progeny trials will be planted with this seed • Combination crosses are also being made of good growing and good rooting clones • Germ-plasm exchange with other companies
