ROOTED CUTTINGS IN BRITISH COLUMBIA'S TREE IMPROVEMENT PROGRAM
John H. Russell
Rooted cuttings are being increasingly used in tree improvement and reforestation programs in British Columbia. Present uses include: 1) an alternative to grafting for cloning selected parent trees for seed orchards and clone banks; 2) a research tool for nursery and field trials to control genetic variability; 3) an alternative to seedlings for reforestation; 4) a means for bulking-up genetically improved seed; and 5) clonal forestry (testing, selection, and deployment of clones). Projects aimed at developing and using these techniques are established in British Columbia.
Cloning parent tree selections. Rooted cuttings have been used in the establishment of British Columbia's seed orchards and clone banks as an alternative to grafting. Cloning of first generation parent tree selections, which were mostly over 60 years old, was usually done by grafting. However, rooted cuttings were used where grafting techniques had not yet been developed.
