Abstract
The somatic chromosomes were studied in the chum salmon (Oncorhynchus keta), the kokanee salmon (O. nerka) and their hybrids, by application of the routine air-drying method. The diploid numbers were 74 for the chum salmon and 58 for the kokanee salmon. Their hybrids showed 66 chromosomes corresponding to a total sum of the haploid number of the parent species. The chromosome formula based on the total numbers of chromosome arms were 100+6m = 106 for the chum salmon, 102+2m = 104 for the kokanee salmon and 101+4m=105 for the hybrids.Keywords
