Includes bibliographic references (p.4). "Jack pine (Pinus banksiana Lamb.) is one of the major reforestation species in Manitoba and Saskatchewan. In 1967 the Canadian Forestry Service initiated a program for the genetic improvement of jack pine, with the purpose of increasing the growth rate and merchantable yields from commercial plantations by improving the genetic quality ofplanting stock. The first genetically improved materials, in the form of grafts for seed orchard establishment, were provided to provincial and industrial cooperators in 1979 and1980.
