摘要
Mitochondrial DNA ND5/6 region was studied by PCR-RFLP analysis among ten representative strains belonging to three subspecies (Cyprinus carpio carpio, Cypri-nus carpio haematopterus and Cyprinus carpio rubrofuscus) of common carp (Cyprinus carpio L.). A total of 2.4 kb frag-ment was amplified and subjected to restriction endonucle-ase analysis with nine restriction endonucleases subsequently.The results indicated that each subspecies owned one hyplo-type and four restriction enzymes (DdeⅠ, HaeⅢ, TaqⅠand MboⅠ) produced diagnostic restriction sites which could be used for discriminating the three subspecies and as molecu-lar genetic markers for assistant selective breeding of com-mon carp.
