Interior Tree Breeding


Overview

Interior spruce, lodgepole pine, interior Douglas-fir, western larch, western white pine, and several broadleaf tree species are important ecological and economic components in British Columbia’s interior forests.  Today, interior spruce and lodgepole pine represent more than half of the seedlings planted annually in British Columbia and they are highly valued for their wood quality, relative to fast-grown plantation trees from elsewhere in the world. 

 

The goal of the tree improvement program in British Columbia is to produce well-adapted seed or cuttings, selectively bred to produce trees with stable and improved volume growth, quality, and pest resistance, while maintaining acceptable levels of genetic diversity. As tree improvement programs on the coast began to show success, the interior tree breeding research program began in the late 1960s, starting with interior spruce (Picea glauca, P. engelmannii, and their hybrids). It has grown to now include breeding and improvement programs for eight interior species and many seed planning zone combinations. The Research Program ensures that comprehensive gene resource management programs are developed and implemented to ensure appropriate development of forest tree materials by conventional plant breeding practices, conservation of genetic resources, and risk reduction (i.e., adaptation and resilience to climate change and other disturbances).

The interior tree breeding research program provides critical support to:

  • address reforestation issues in the interior such as maladaption of planting stock and achievement of free-growing status;
  • understand how to adapt forest management activities to climate change and its risks;
  • respond to forest health risks such as spruce terminal weevil, white pine blister, mountain pine beetle, and root diseases; and
  • improve industry competitiveness through protection and enhancements of reforestation investments and long-term volume gains.

Tree Breeding Programs

Research Highlights

  • Identified, selected, and grafted 65 forward selections of interior spruce from the Prince George Series 1st-and 2nd-generation genetic tests.

  • Raised and released a population of terminal weevils for screening two interior spruce genetic tests (PG Series Two and the McLeese Lake somatic embling trial) to further evaluate resistance.

  • Measured 3-year height of interior spruce on 18 sites in the BC/Alberta climate change project.

  • Measured 21-year height and diameter of interior Douglas-fir on three sites in the Cariboo Transition Series II genetic tests, 20-year height on four West Kootenay high elevation sites, and 20-year height on three Nass Skeena sites.

  • Measured 15-year height and diameter of western larch on four sites in the Nelson Series I genetic tests.

  • Measured realized genetic gain trial sites for southern and central interior seed planting units (SPU) (4 and 6, respectively).

  • Measured the seed orchard realized genetic gain trial sites for the southern interior.

  • Selected 12 southern interior sites for the first phase of the “Facilitated Migration of Multiple Species Adaptational Trial.” Acquired Class A and Class B seedlots for the first phase of this trial.

  • Conducting progeny test selections for the Central Interior Western Gall Rust Resistance, PG low Lodgepole pine SPU, and NE low Lodgepole pine SPU. Expansion of seed orchards continues with scion collection and grafting completion scheduled for spring 2008.

  • Involved in planning the Western White Pine Genetics and Management Workshop in Vernon, June 17-18, 2008.

  • Presented a paper at the joint meeting of the Southern Forest Tree Improvement Council and Western Forest Genetic Association in Galveston, Texas, on a study conducted to model environmental effects on wood density in lodgepole pine.

  • Presented a paper on western larch tree improvement and seed deployment in British Columbia at Larix 2007: International Symposium of the IUFRO Working Group S2.02.07, Quebec City, Que, September 17 – 21, 2007.

  • Published a paper on the evaluation of genetic variation of resistance and attack of mountain pine beetle on lodgepole pine.

  • One of three Canadian delegates at the XXX Reunion of the FAO, North American Forest Genetics Working Group, Corvallis, Oreg, September 24-27, 2007.Top

Extension and Consultations

  • Organized three stops on field tour at the BC Seed Orchard Manager’s Meeting, Prince George, B.C., June 26-28, 2007.    

  • Consultation on seed transfer in several interior Forest Districts.

  • Jaquish, B. 2007.  Interior spruce tree improvement in British Columbia. Presentation at the SAB program review of the Treenomix BC research program.  University of British Columbia, June 14, 2007.

  • Jaquish, B. 2007.  EP672 - Effects of altitudinal and lateral displacement of white and Engelmann spruce provenances: Prince Rupert plantations. Presentation at the Northern Silvicultural Committee Summer Field Tour, Smithers, B.C., June 19, 2007.

  • Forest Tree Genetic Resource Conservation and Management Challenge Dialogue, Co-chair—A dialogue with stakeholders to create a collective vision and strategy for genetic resource conservation and management to support sustainable forest management in British Columbia, congruent to the range of values outlined in the Provincial Chief Forester’s Sustainable Forest Management framework.

  • Forest Genetics Council of British Columbia, Interior Technical Advisory and the Operational Tree Improvement Project Review Committees—The Council guides tree improvement activities in the province. Research Branch forest geneticists actively participate in providing technical and policy information to the Council and in reviewing and evaluating operational tree improvement projects.

  • Long-term Multi-species Facilitated Migration Trial Planning—Responsible for all aspects of selection, testing, breeding, and related research of interior tree species.

  • UBC Genome BC Forestry Project, Co-operator—Research project to study genome sequencing of poplar and spruce in order to identify the genetic blueprints that determine characteristics such as resistance against forest insect pests, adaptation to climate change, and wood quality.Top
