Operational Use of Vegetative Propagation in Forestry: World Overview of Cloning and Bulking

Rooted cuttings (stecklings) are used world-wide for cloning forest trees and for bulking scarce or valuable forest tree seed. In cloning, numerous copies are made of very few genotypes, and each genotype (clone) is tracked and managed separately. In contrast, bulking involves making relatively few copies of many genotypes of a selected family or seed lot. Management and tracking are normally at the family level. Greater genetic gains can be achieved by cloning, but extensive and lengthy testing programs are required. With bulking, genetic gains are not as high but can be captured more rapidly.
