Karyotype of native carp from the Amur river, Cyprinus carpio haematopterus, was studied. Diploid chromosome number 2n = 100 was found. Because of the absence of any chromosome banding data, the karyotype was divided as precisely as possible into eight groups according to the morphology of particular chromosomes: group A composed of 6 pairs of mediocentrics, group B with 8 pairs of metacentrics with non-median centromere position, group C with 3 pairs of large submetacentrics, group D with 15 pairs of submetacentrics, group E with single pair of achromatic-region-carrying submetacentrics, group F with 2 pairs of subtelocentrics, group G with 9 pairs of subtelocentrics, and group H with 6 pairs of clearly acrocentric chromosomes. These results were compared with remaining few studies on the chromosomes of wild carp populations, and the differences between the results of various authors and the present study were briefly discussed.
