Embodiment
[0016] A method for selecting and breeding new strains of long oyster meat quality traits, the operation steps are:
[0017] (1) Select 9 female and male Oyster oysters with regular shell shapes as breeding broodstock, use partial factorial experimental design, conduct single-to-single mating and insemination, establish 25 full-sib families, mark each family separately, and adopt strict Isolation measures for larval culture. In the growing stage, each family line was placed in Kongtong Island in Yantai, Rushan in Weihai and the Yellow River Delta sea area in Dongying for cultivation.
[0018] (2) Determination of the true value of glycogen content and total protein content in the meat quality traits indicators of 25 full-sib families of long oyster, and the two apparent indicators of shell length and shell width;
[0019] (3) The genetic parameter analysis software ASReml (3.0, UK) was used to compare the heritability of the two meat quality traits, the glycogen content and t...
