Using starch gel electrophoresis of proteins, we examined variation at 24 genetic loci in five species (three general of the Subfamily Danioninae (Class Pisces, Family Cyprinidae) inhabiting In Korea. The average degree of genic variation of the Subfamily Danioninae (A=1.8, P=16.5%, HD=0.043, HG=0.049) was far less than that of the fresh water fishes in general. But the degree of genic variation of A. chinensis (P=32.5 HD=0.100, HG=0.119) was highe, than other fishes and the value of O. biders was the lowest (P=4.2%, HD=0.008, HG=0.008). The average genetic similarities among the populations in each species of A. chinensis, Z. platypus, Z. temmincki MS type, Z. temmincki W type, and O. widens were S=0.902, 0.899, 0.990, 0.914, and 0.992, respectively. The average genetic similarity of A. chinensis to the other species was the lowest value of S=0.235, whereas that between two species of Z. temmincki was the highest of S=0.822. Genetically, Z. plypus is more similiar to O. widens than ho species of the same genus Zacco. Based on estimated divergent time of 5 species of the Subfamily Danioninae (7.6 to 0.9 million years) it is assumed that they are speciated during late Pliocene to middle Pleistocene epoch.
