Integrating genomic selection into the lodgepole pine breeding program in British Columbia

Research Interests

Tree breeding programs for northern conifers have very long generation times that can span decades depending on the target trait. A typical tree breeding program has three stages: breeding to create new allele combinations and allow recombination to occur, testing of the target trait and selection, and a period of time for the new selections to become sexually mature before breeding can begin. Genomic selection is a new tool being used by breeders in various fields to minimize the testing time in the breeding cycle thus shortening the generation time. Implementing genomic selection in an operational tree breeding program will depend on the trade-off between accuracy of the predictions and shorter generation times.
