The proportion of polymorphic loci per population P averaged over the 6 species was . The average number of alleles locus A L was . The average observed and expected heterozygosities Ho He were and respectively. Only a small amount 7 of the observed genetic variation appeared to be interpopulational. Among the 6 species o serrata and Q dentata were genetically less variable than the others. Three loci could be used as markers for distinguishing Q acutissima and o 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. allozyme genetic variation I Quercus species Resume Variabilité allozymique Chez 6 espèces de chênes indigenes de Corée. La variability allozymique a été étudiée dans 28 populations appartenant à 6 espèces de chênes indigenes de Corée à partir de données issues de 6 loci Quercus acutissima Carruth Q aliena Bl Q dentata Thụnb Q mongolica Fisch Q serrata Thunb et Q variabilis Bl. Le nombre moyen d alleles A L était de 2 26. Les heterozygoties observées et théoriques Ho HJ étaient de 0 302 et 0 298 respective-ment. La variabilité entre populations ne représentait que 7 de la variabillté totale. Parmi les 6 es-pèces Q serrata ef Q dentata étalent les moins variables. Trois loci permettaient de distinguer Q acutissima ef Q variabilis des 4 autres espèces. Le calcul des .
