When artificially regenerating by direct seeding, genetic principles should be considered. Seeding the proper provenance reduces loss to frost, insect and disease. In some species, introduced provenances are preferable as increased growth can be obtained. Seed collection and seed production areas provide some genetic gain at minimal costs. Until problems in direct seeding are overcome, most of the improved seed should come from seed collection and production areas. Greatest genetic gains result from selected plus trees established in seed orchards. At present any seed from orchards should be used for planting stock, but eventually as greater amounts of orchard seed are available, some may be available for seeding programs. Mention is made of the present and anticipated regeneration program for Ontario, and Ontario's approach to producing improved seed for the Province's needs.
