英文摘要Oysters are of the most economically important bivalves worldwide. It has high nutritional value and is regarded as a good source of proteins, lipids, glycogen, and amino acids. C. gigas and C. angulata are allopatric congeneric dominant oysters that are widely cultivated in the northern and southern coast of China, and have shown remarkable differentiation in the nutritional content. Interspecific hybridization and backcross of the two species are effective ways to improve the nutritional quality of the oyster. Sixteen progenies were constructed based on a 4x4 diallel crosses among broodstock of C. gigas (G), C. angulata (A) and their hybrids GA(H) and AG(R). The glycogen, fatty acids, and amino acids performance of these progenies were evaluated in 22 months after fertilization. The glycogen content of AA was significantly lower than that of the other 15 progenies (P<0.05), while only the GH progeny was significantly higher than the GG (P<0.05), with a heterosis value of 21.06%. The backcross progenies GR exhibited significantly higher saturated fatty acids, eicosapentaenoic acid (EPA), and polyunsaturated fatty acids (PUFAs) content than those of GG (P<0.05), and did not show significant differences from AA. The AA showed significantly higher content of total amino acids (TAAs) than GG (P<0.05). The AH progeny displayed significantly higher taurine (Tau) content than GG (P<0.05), and the heterosis value was 27.88%. Therefore, the backcross breeding was shown an effective way to improve the glycogen, fatty acids, and TAAs of GG, and the glycogen of AA. This study provided useful information to characterize the benefits of backcrossing in nutritional quality, which will facilitate the production of differentiated products and increase the efficiency of the oyster industry.
