Chloroplast DNA Variation in the Sympatric Zone of Lodgepole pine (Pinus contorta Dougl.) and Jack Pine (P. banksiana Lamb.)

A chloroplast DNA restriction fragment length polymorphism (RFLP) and its relationship with cone morphology was studied in a sympatric population of lodgepole pine and jack pine. Novel cpDNA variants, found only in or near the sympatric region, occurred in approximately 5% of the individuals of this population. Chloroplast DNA typical of jack pine was associated with cone morphology typical of lodge pole pine and hybrids, suggesting that cpDNA of jack pine may be functional in the nuclear genetic background of lodgepole pine.
