title: Mitochondrial DNA products among RAPD profiles are frequent and strongly differentiated between races of Douglas-fir.
abstract: Racial differentiation and genetic variability were studied between and within the coastal, north interior, and south interior races of Douglas-fir using RAPD and allozyme markers. Nearly half of all RAPD bands scored (13: 45%) were found to be amplified from mitochondrial DNA. They exhibited maternal inheritance among hybrids and backcrosses between the races, and were much more highly differentiated (GST = 0.62 for haplotype frequencies) than were allozymes (GST = 0.26). No evidence of hybridization or introgression was detected where the coastal and interior races come into proximity in central Oregon.
