What are “parent trees” and why must they be identified with the ministry prior to registering seedlot or vegetative lots collected from them?
A. A parent tree is a tree that has been selected in the wild or from a conventional tree breeding program for specific traits, such as improved growth and form or resistance to insects or disease. These parent trees are used to produce seed in a seed orchard, or vegetative material in a stoolbed. Knowledge of the origin and testing history of parent trees is critical for determining the collection criteria and transfer limits for lots produced from them.
