摘　　要：筛选多态性高、特异性好、片段大小适中的10个长牡蛎微卫星位点进行优化组合,根据扩增片段大小及同一荧光不重叠原则构建了两组五重PCR体系。运用CERVUS 3.0软件对0527组27个长牡蛎全同胞家系的643个子代和0612组27个全同胞家系382个子代分别进行亲权鉴定。结果发现,用两组微卫星五重PCR鉴别时,在0527组和0612组的鉴定成功率均为100%;只用第一组微卫星五重PCR,可以将0527组96%的子代和0612组96%的子代鉴定到亲本;只用第二组微卫星五重PCR,可以将0527组97%的子代和0612组95%的子代鉴定到亲本。本研究中筛选出的两组微卫星五重PCR体系在两组家系中的鉴定效率均较高,可以快速有效地将子代个体鉴定至所属父母本,在长牡蛎家系鉴定中具有很好的应用价值。We tested two sets of high-level 5-multiplex PCRs for efficient genotyping in the Pacific oyster（Crassostrea gigas）. Ten loci were selected based on polymorphism, reliability, and allele size range. They were divided into two groups according to allele size and labeled with four different fluorescence dyes, so that loci in the same color were not be overlap in size. In addition, we performed a paternity test for 27 full-sib families and 643 offspring of Group 0527 and 27 full-sib families and 382 offspring of Group 0612 with software CERVUS 3.0. Parentage analysis demonstrated that 100% of all offspring were allocated unambiguously to the unique pair of parents when two sets of 5-multiplex PCRs were used for Groups 0527 and 0612. The assignment success for the two groups was 96% based on MS 1（the first 5-multiplex PCR）. However, the assignment success was 97% and 95% based on MS 2（the second 5-multiplex PCR） for Groups 0527 and 0612 respectively. Therefore, the two sets of 5-multiplex PCRs can be used for rapid and efficient parentage assignment in the Pacific oyster.
