| Abstract: |
| The AFLP(amplified fragment length polymorphism)technique was used to analyse the genetic diversity in four scallop species,Patinopecten yessoensis,Argopecten irradians,Chlamys nobilis and C.farreri.The genetic similarity indexes of these four species are 0.841 5,0.786 3,0.719 0 and 0.673 1,while Shannon diversity indexes are 43.52,58.87,80.16 and 92.83,respectively.As analyzed,the genetic diversities in two native species,i.e.,C.farreri and C.nobilis,are higher than those in other two introduced species,A.irradians and P.yessoensis.The results also showed that C.nobilis and C.farreri shared the most common loci.The genetic distance indicated that C.nobilis and C.farreri are closely related.Moreover,out of 510 AFLP markers,21 specific bands are found to distinguish the four species scallops and these markers may be applied to the specific germplasm characterization and molecular assistant classification in scallops. |
