Allozyme variation at 6 loci was studied in 28 populations of the 6 oak species native to Korea: Quercus acutissima Carruth, Quercus aliena Bl, Quercus dentata Thunb, Quercus mongolica Fisch, Quercus serrata Thunb, and Quercus variabilis Bl. The proportion of polymorphic loci per population (P) averaged over the 6 species was 74.6%. The average number of alleles/locus (A/L) was 2.26. The average observed and expected heterozygosities (Ho, He) were 0.302 and 0.298, respectively. Only a small amount (7%) of the observed genetic variation appeared to be interpopulational. Among the 6 species, Quercus serrata and Quercus dentata were genetically less variable than the others. Three loci could be used as markers for distinguishing Quercus acutissima and Quercus variabilis from the other 4 species. Based on genetic identity, the 6 oaks were also clustered into 2 groups. This approach yields results similar to the current taxonomic treatment by morphological characteristics.
