Molecular DNA variations in koi (Cyprinus carpio) of various color patterns were studied by random
amplified polymorphic DNA (RAPD) PCR. For DNA examination, nine strains were divided into two
groups. Group one consisted of sanke, showa, yamatunishaki, kohaku and gold ohgon. Group two
consisted of platinum ohgon, orenji ohgon, nezu ohgon and kohaku. Four (ZG4, ZG8, I18 and
18498) of the 29 primers tested for this study amplified the DNA, resulting in a polymorphic pattern.
Genetic similarity between strains, as calculated by bandsharing (BS), showed an identical pattern
in yamatunishaki and sanke (99%) and close similarity between ohgon and sanke (94%),
ohgon (gold) and kohaku (88%), and sanke and kohaku (94%) with primers ZG4, ZG8 and I18.
Using these same primers, the BS of showa, compared with all the other strains, varied from 80 to
88%. Much higher genetic variation (low BS) was found in the comparisons between platinum
ohgon, orenji ohgon, nezu ohgon and kohaku. In this case, the BS value varied from 28 to 75%.
