摘　　要：用栉孔扇贝Chlamys farreri、海湾扇贝Argopecten irradians、虾夷扇贝Patinopecten yessoensis和华贵栉孔扇贝Chlamys nobilis进行多种杂交组合及自交,试验分为8组,即海湾扇贝♀×虾夷扇贝♂、虾夷扇贝♀×海湾扇贝♂、虾夷扇贝♀×华贵栉孔扇贝♂、虾夷扇贝♀×栉孔扇贝♂、栉孔扇贝♀×虾夷扇贝♂5个杂交组和虾夷扇贝、海湾扇贝、栉孔扇贝3个自交组,在不同温度下比较了各杂交组配子的亲和力,同时对胚胎发育及早期幼虫的生长结果进行比较。结果发现,在适温范围内各杂交组正、反交均可受精,其中栉孔扇贝♀×虾夷扇贝♂、虾夷扇贝♀×栉孔扇贝♂杂交组受精率较高,可达80%以上;杂交子一代的D型幼虫大小性状与母本相似。另外还对杂交组合受精率、成活率较低的成因进行了探讨。Different hybridization was conducted among Argopecten irradians, Patinopecten yessoensis, Chlamys farreri, and Chlamys nobilis. There were five hybridizing groups P. yessoensis ♀×A. irradians ♂3 , A. irradians ♀× P. yessoensis♂ , and P. yessoensis ♀× C. farreri ♂ , C. farreri ♀×P. yessoensis ♂ ,P. yessoensis ♀× C. nobilis ♂ , and three breeding groups in the same species P. yessoensis, A. irradians, C. farreri as control groups. Compatibility of gametes, embryonic development and larvae growth from each test group was compared at different water temperatures. The results showed that eggs from all hybridizing groups were fertilized with a fertilization rate of over 80% for reciprocal crosses of P. yessoensis and C. farreri, lower than those for their control groups. The sizes and characteristics of D - larvae from the first generation are similar to those of their females.
