摘要
A process for polycross breeding a Manila clam pedigree, includes: providing present Manila clam pedigrees of different shell color types as parents; ecologically maturing the parents; reciprocally hybridizing the parents by every two of different shell color types to obtain offsprings thereof; nurturing the offsprings until gonads thereof mature synchronously; and hybridizing the matured offsprings with each other to obtain at least a four-way cross pedigree accumulating all valuable genes of the parents.
