Objective To bolt RAPD marker from Carassius auratus red variety inbred strain C1HD.Methods Using 20 random primers from 80 primers,8 samples of inbred strain C1HD and common Carassius auratus red variety were analyzed by random amplified polymorphic DNA(RAPD),respectively.Results A primer(S333) was observed to produce a specific band.Conclusion This band could be used as a molecular marker for discriminating Carassius auratus red variety inbred strain C1HD from common population.
