Culture method of hybrid new variety of Argopecten irradias and Argopecten purpuratus

The present invention relates to a method for cultivation of purple sea scallop new hybrid varieties. Firstly, bay scallop eggs and purple scallops sperm to create multiple sea purple filial generation pedigree, select elite hybrid families according to the phenotype of each hybrid pedigrees, and then select the best individual hermaphrodite from elite hybrid pedigrees, after ripening were self-fertilization establishing a plurality of inbred lines; select superior families again from the inbred line, select hermaphrodite of excellent pedigrees further excellent individuals continue selfed; this same manner continuously selfing more than three generations, i.e., stable genetic and grow fast, individual large, wide temperature tolerance range of new hybrid varieties of purple sea scallops. The method of the present invention can be also achieved cultivated population. Given the characteristics of the fine purple sea new hybrids, while the present invention has a bay scallop and purple scallop, thus achieving in the North Sea and Dalian Qingdao breeding, production increased by more than 30% bay scallop.
