Seed production method of a blue-purple mantle Saffron strain

Abstract

The invention discloses a seed producing method for a tridacna crocea strain with bluish violet pallium. According to the method, in order to shorten the cultivating period of the new tridacna croceastrain, the parent screening rule is adopted for the first time; the theory that blue iridocyte in the pallium of tridacna develops, and consequently the pallium shows bluish violet is adopted in combination; multiple times of parent selection is adopted, blue iridocyte homozygotic type parents are obtained, the parents breed offsprings again next year, and the 100% tridacna crocea strain with thebluish violet palliu is obtained. The strain is attractive in appearance, the economic value is improved by 4-5 times, a new product is provide for a seawater ornamental aquarium market, and a new way is also provided for tridacna variety breeding. According to the seed producing method, the breeding period of the tridacna color new strain is shortened to 2 years from 5-6 years, the seed production period is greatly shortened, the breeding risk is reduced, the breeding benefits are increased, and the new path is provided for new variety breeding. The seed producing method has the advantages of being high in feasibility, high in practicality and the like.

Description

Technical field:

[0001] The invention belongs to the technical field of shellfish genetics and breeding in marine agriculture, and in particular relates to a seed production method and application of a blue-purple mantle safflower clam strain. Background technique:
