　　采用完全双列杂交配组方法，以三元杂交菲律宾蛤仔(Ruditapes philippinarum)壳色品系两道红白斑马(TrWz)和红白斑马(OWz)为材料，进行了2种壳色蛤仔品系间的聚合杂交研究。结果表明，浮游期间杂交组幼虫表现出微弱的的生长优势及一定程度的存活劣势；中间育成期间稚贝表现出微弱的生长劣势及明显的存活优势。三元杂交自交组两道红白斑马子代均出现了壳色分离现象，而红白斑马子代均为白斑马，且壳面花纹颜色为红色；正反交组子代均表现为两道红白斑马，其壳色表达具有显著的母本效应；但其壳色表现呈现出非伴性遗传。

In order to improve the phenotypic character of Manila clam Ruditapes philippinarum, the convergent cross was conducted between the Two band red-white zebra strain and the Red white-zebra strain from three way crosses of Ma-nila clam in October 2010. It was consisted of four experimental groups, which includes two self-fertilized groups (TrWz♀×TrWz♂, OWz♀×OWz R♂) and two reciprocal groups (TrWz♀×OWz♂, OWz♀×TrWz♂). The phenotypic traits, heterosis and the genetic mechanisms of shell color were examined in this text. These results showed that the faint growth heterosis and the survival hybrid weakness were observed during the larval plantonic stage, whereas the nil growth disadvan-tages and the obvious survival heterosis occurred during the spat culture. The genetic segregation of shell color was observed for the progenies of Two band red-white zebra strain, but no segregation for the progenies of Red white zebra stain. The shell color of reciprocal experimental groups was similar to maternal parents and the shell coloring and sex was not linkage.
