The present application belongs to the technical field of preparation of excellent commercial seed of economic marine
shellfish, and particularly relates to a high-efficiency method for preparing interspecific three-way
hybrid of Argopecten
genus scallop. The method uses a selected and purified male sterile and female fertile
hybrid Argopecten mactrolineatus as a female parent, and a restocked
Argopecten purpuratus as a male parent, to produce a "Argopecten mactrolineatus
Argopecten purpuratus" three-way
hybrid scallop commercial seed with hybrid vigor and outstanding
stress resistance. The method can realize large-scale, continuous and efficient
hybrid seed production, and has the advantages of simple operation, labor saving, low dependence on personnel, and the like. The hybridization rate is increased from less than 30% in the prior art to more than 90%, and the efficiency of interspecific
hybrid seed production and the purity of the seed of the protandrous Argopecten
genus scallop are significantly improved.
