摘要：

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 (G(ST) = 0.62 for haplotype frequencies) than were allozymes (G(ST) = 0.26). No evidence of hybridization or introgression was detected where the coastal and interior races come into proximity in central Oregon.
