520 |a"In the spring of 1982, jack pine (Pinus banksiana Lamb.) family-test plantations in eastern Manitoba were measured 10 years after planting. These plantations are part of a jack pine genetic improvement program that was initiated by the Canadian Forestry Service (CFS) to increase the growth rate and merchantable yield from commercial plantations in Manitoba and Saskatchewan (Klein 1982a, b). Establishment of seed orchards using families selected on the basis of this measurement began with grafting in March 1983 and is scheduled to be completed by 1987. Results were also used to select areas where genetically superior wild seed can be collected until the seed orchards produce sufficient seed to meet planting requirements. This note presents measurement results and describes the criteria used for selection"--Introd., p. [1].
