Pinus densiflora is a perannuial coniferous species to Asia. The level of genetic diversity ofthis species was surveyed using starch gel electrophoresis at putative six enzyme loci from 17 natural populations in Korea. Results from nineteen loci indicated that genetic diversity was higher and population divergence was found between genetic identity statistics and geographic distance between populations. Although the range in genetic diversity statistics among populations was low, genetic drift and gene flow did not appear to play major roles in structuring genetic variation. I concluded that the level of genetic diversity maintained within P. densiflora populations, and the level of population divergence was influenced by its status as forest and mode of gene flow.
