外文摘要：The bay scallop southern subspecies, A. irradians concentricus , is an important cultured bivalve in southern China. However, the demand for superior stocks with faster growth and larger size has been increasing. To improve the stock of this scallop, interspecific hybridization was carried out between A. purpuratus (PP) and A. irradians concentricus (SS). The results showed that both reciprocal crosses developed normally and exhibited significant heterosis in important production traits such as growth and survival. At harvest, the heteroses in the SP and PS cohorts were 34.97 and 21.74 in shell height, 138.35 and 79.48 in wet weight, 155.12 and 40.60 in soft -body weight, and 349.60 and 214.40 in adductor muscle weight, respectively. The crossbred cohorts PS and SP outperformed the purebred cohort SS by 30.68% and 82.05% in whole body weight, and by 94.55% and 178.22% in adductor muscle weight, respectively. Morphological and molecular evidence indicated that the derived offspring were true hybrids between the two Argopecten scallops. The gonads of most hybrids were fully feminized and functionally male -sterile, although only 0.79-4.66% of the spawned eggs were able to hatch and resulted in normal backcross offspring. The results from this study indicate that hybridization between A. purpuratus and A. irradians concentricus may provide a promising way for genetic improvement of existing A. irradians concentricus brood stocks in China.
