Genetic Diversity of Marginal Vs. Central Populations of Pitch Pine and Jack Pine

Pitch pine ( Pinus rigida Mill.) and jack pine ( P. banksiana Lamb.) were examined electrophoretically to compare the extent and distribution of genetic variability between marginal and central populations. Seeds were collected from three central pitch pine (MA, PA, NJ), three marginal pitch pine (VT, PQ), two central jack pine (ON) and two marginal jack pine (NY, NH) populations. Starchgel electrophoresis was used to identify and confirm alleles at 33 loci in pitch pine and 29 loci in jack pine.
