Eighteen kinds of enzymes and two kinds of blood proteins extracted from 350 frogs belonging to three populations (Hiroshima, Suwon and Beijing) of Rana nigromaculata HALLOWELL, two populations (Konko and Maibara) of R. b. brevipoda ITO and one population (Utsunomiya) of R. brevipoda porosa (COPE), two populations (Beijing and Shandong) of R. p. plancyi LATASTE, one population (Suwon) of R. plancyi chosenica OKADA, one population (Chiayi) of R. plancyi fukienensis POPE, three populations (Luxembourg, Poland and Firenze) of R. lessonae CAMERANO, three populations (Wien, Ukraine and Heidelberg) of R. esculenta LINNAEUS and three populations (Belgorod, Roscoff and Adana) of R. ridibunda PALLAS distributed in the Palearctic region were analyzed by the method of horizontal starch-gel electrophoresis. These enzymes and blood proteins were controlled by 1∿15 (5.3) alleles which produced 1∿25 (8.5) phenotypes. The mean proportions of heterozygous loci per individual were 2.2∿57.7% (14.8%) and the mean proportions of polymorphic loci were 3.9∿61.5% (30.6%) in the 19 populations belonging to the six species and three subspecies. The mean numbers of alleles per locus were 1.04∿1.88 (1.36) at the 26 loci of the 19 populations. In the East, the genetic distances between R. nigromaculata and R. brevipoda and between R. nigromaculata and the three populations (Beijing, Shandong and Suwon) of R. plancyi were 0.431∿0.684 (0.523) and 0.500∿0.838 (0.669), respectively, while those between R. brevipoda and the latter were 0.638∿0.772 (0.717). In contrast, the genetic distances between R. plancyi fukienensis and R. nigromaculata and between the former and R. brevipoda were 0.439∿0.571 (0.498) and 0.293∿0.381 (0.344), respectively. It was especially interesting that R. brevipoda is nearly related to R. plancyi fukienensis. In Europe, the genetic distances between R. esculenta and R. lessonae, between R. esculenta and R. ridibunda, and between R. lessonae and R. ridibunda were 0.164∿0.245 (0.197), 0.165∿0.289 (0.231) and 0.537∿0.688 (0.609), respectively. The genetic distances between the three species in the Far East and the three species in Europe were 1.183∿2.173 (1.647). The dendrogram drawn for the pond frogs distributed in the Palearctic region shows that it agrees well on the whole with the prevailing classification.
