Excerpt from Genetics of Jack Pine Jack pine is an important species for planting and direct seeding in the Lake States and throughout much of the boreal forest of Canada, where it is a major source of pulpwood, lumber, and round tim ber. It is highly variable in climatic adaptation, growth, and form and exhibits great genetic diversi ty of silvicultural significance. Although referred to early in the 2oth century as a frugal scrub, its cur rent high economic value, genetic variability, silvi cultural simplicity, and ability to grow on less fer tile and drier soils than are required by other sym patric species make jack pine a prime candidate for genetic improvement by selection, breeding, and controlled seed production. Jack pine is in the Subgenus Pinus, Section Pinus, and Subsection Contortae along with lodgepole pine, Virginia pine, and sand pine.

Excerpt from The Genetics of Lodgepole Pine Lodgepole pine is a small tree, and only recently has it been heavily utilized in its native range. In northwestern Europe, however, the ability of some seed sources to grow well on poor sites and in cold climates has interested foresters for many years, and the species is now widely planted in the British Isles and Sweden. The oldest fossils of lodgepole pine are several million years old, but there is no evidence that the species was widespread until the late Pleistocene. It was an important pioneer following glacial melting, and occupied its extensive northern range by migration from the south and possibly from far-northern refugia. Lodgepole pine has been successfully crossed with only two other species: jack pine and Virginia pine. Crossability with jack pine is moderately high, and the two species hybridize naturally in Canada. Many northern Rocky Moun tain stands have jack pine-like characteristics, but the extent of introgression from jack pine is uncertain. Lodgepole x jack hybrids are fertile, but pollen abortion is sometimes high. Hybrids of Sierra Nevada parentage have not grown well in most other environments.
