Tree Improvement through Controlled Pollination Breeding at the JDI Parkindale Seed Orchard
J.D. Irving, Limited’s (JDI) tree improvement program started almost 40 years ago.
The tree improvement process included selection of the best individuals in the region’s forests for qualities like rapid growth, tree straightness, and freedom from insect and disease problems. Traditional methods of grafting and planting these trees for quality seed production began at the Parkindale Seed Orchard.
This process continues today, allowing for cross pollination among the best trees to produce well-adapted genetically-superior seed for use in the nurseries.
Regular seed production is wind pollinated – trees in the orchard cross-pollinate as pollen is released into the air and lands on the receptive female flowers of another tree.
JDI also produces seeds with two known parents for testing across the region. These trees also form the basis for the next generation of tree improvement.
