中文摘要	Interspecific hybridization can generate heterosis, which is proven to be a useful tool in selective breeding programs for oyster culture. Crassostrea angulata and C. ariakensis are two important economic shellfish species in China. We conducted 2 x 2 reciprocal crosses to determine whether these two species can cross-fertilize and their hybrids can hatch, survive and perform heterosis. Fertilization was found symmetrical without delay. The rate of fertilization success of C. angulata a (TM) Euro x C. ariakensis a (TM), was lower than that of C. ariakensis a (TM) Euro x C. angulata a (TM),, and the success rate of both hybridizations was lower than that of two intraspecific crosses each. During the planktonic period, survival rate of the progeny was lower in the hybrid crosses than in the intraspecific crosses. On day 360, mean shell height of the progeny of C. angulata a (TM) Euro x C. angulata a (TM), was highest, which was followed by that of C. angulata a (TM) Euro x C. ariakensis a (TM),, C. ariakensis a (TM) Euro x C. ariakensis a (TM), and C. ariakensis a (TM) Euro x C. angulata a (TM), in a descending order. Morphology of adults produced by the hybrid crosses was similar to that of C. angulata. Both hybrids underwent normal gonad development and produced mature gametes in the mating season. This study provided new insights into the quantitative traits in interspecific crosses of Crassostrea species, thus being of guidance value for selective breeding of oyster.
