The invention relates to the technical field of marine economic shellfish cross breeding, in particular to a breeding method based on argopecten purpuratus, argopecten irradians and Argopecten irradians concentricus three-way hybrid scallop commodity fries. The argopecten irradians and the Argopecten irradians concentricus are subjected to intersubspecific hybridization, then the obtained first-generation scallops of the intersubspecific hybridization and the argopecten purpuratus are used as seed scallops and are respectively subjected to high selfing purification, and the obtained purified sea and ink sea (or ink sea) hybrid scallops and the argopecten purpuratus are subjected to interspecific hybridization; therefore, large-scale preparation of the sea-black-black-purple (or black-sea-black-purple) three-way hybrid scallop commodity offspring seeds is realized. According to the method for preparing the three-way hybrid scallop commodity offspring seeds of the Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus, Argopecten purpuratus,
