Sixty wild rate (fifty eight of Rattus norvegicus and two R rattus) were caught from Seoul, Kyonggi, Kangwon, Honam, and Yongnam areas between August and October 1992. From liver homogenates of the wild rats, isoenzyme patterns were analysed by starch gel electrophoresis. Using 9 enzyme systems, eight electrophoretic types were identified among wild rats with genetic diversity per locus between 0.00 and 0.49 (Mean 0.15). R rattus from Kyonggi (Kanghwa) and Kangwon (Cholwon) were distinct from R norvegicus from nine regions with 0.581 in genetic divergence. Therefore genetic divergence was different not only in interspecies(0.581) but also in intraspecies(0.111~0.375). These data suggested that isoenzyme electrophoresis could be used as a potential application in taxonomic studies of wild rats.
Key Words: Rattus norvegicus, R rattus, isoenzyme, genetic divergence
