When C.farreri×P.yessoensiswere tested by using6pairs of microsatellite primers which could be applied to boththe two kinds of scallops,the specific bands could be amplified fromeachone of the 6 pairs,among which,the specific bands fromboth agnate and maternal colony could be distinguished obviouslyinthe amplified products of P13F449 and KMY134,and accordinglythe hybrid identity of hybrid generations could be affirmed.
