This publication reports on the results of over two decades of research in the Sitka Spruce Breeding Program. The objective of the Sitka spruce (Picea sitchensis [Bong.] Carr.) breeding program is to develop, propagate, and deploy genotypes with robust resistance to the white pine weevil (Pissodes strobe Peck). The program is based on research that has been conducted on the extent and nature of genetic resistance in Sitka spruce populations in British Columbia. This research has international stature and provides a successful model for incorporating the results of research on natural genetic resistance to insect pests into applied breeding programs and proactive forest management.
