Breeding method of a new strain of golden-yellow adductor bay scallop

Abstract

The invention discloses a breeding method for a golden yellow adductor muscle bay scallop new strain. New bay scallop products ''Zhong Ke Red'' and ''Zhong Ke NO.2'' serve as core collection groups, individuals with the adductor muscle being golden yellow are selected from the core collection groups as parent oysters so as to construct self-fertilization families, and the character of the golden yellow adductor muscle is subjected to rapid purification through family selection; the ''Zhong Ke Red'' self-fertilization family and ''Zhong Ke NO.2'' self-fertilization family are selected, wherein the ''Zhong Ke Red'' parent oysters and ''Zhong Ke NO.2'' parent oysters are the same in number, the hybridization group based on the two new products is constructed, the stability of the golden yellow character of the adductor muscle of the hybridization group is verified through breeding in different sea areas, and the golden yellow adductor muscle bay scallop new strain is obtained. The golden yellow character of the adductor muscle is rapidly purified through the family self-fertilization method, and the genetic diversity of the breeding strain is enriched by adopting a method of hybridization between varieties; and the nutritive value of the bay scallop is obviously increased, the product additional value and the breeding enterprise economic benefits are increased, and market prospects are wide.

Description

technical field [0001] The invention relates to a shellfish genetic breeding technology, in particular to a method for breeding a new strain of golden adductor bay scallop. Background technique [0002] Gulf scallops, belonging to the phylum Molluscs, Phyllobranches, Heterocylinda, Scallopidae, and the genus Scallop, are native to the Atlantic coast of the United States and were first introduced to my country in 1982. They have the advantages of fast growth, strong stress resistance, and wide adaptability. , is an important farming economic shellfish in northern my country. About 90% of bay scallops are sold in the form of adductor muscle after processing, so the adductor muscle has important economic value. Thanks to the unremitting efforts of breeders, gratifying progress has been made in improving the size of adductor muscle. However, with the expansion of breeding scale, the phenomenon of product homogeneity and industrial high yield and low efficiency is serious. Theref...

Problems solved by technology

Thanks to the unremitting efforts of breeders, gratifying progress has been made in improving the size of adductor muscle. However, with the expansion of breeding scale, the phenomenon of product homogeneity and industrial high yield and low efficiency is serious. Therefore, it is urgent to inherit the quality of adductor muscle. to improve
