摘要: The growth superiority of hybrid scallop Chlamys farreri (♀) × Patinopecten yessoensis (♂), as the following successive generation selection have been reported. However, data about genetic diversity in those population remains unexplored. In this study, structure analysis F1, F2 and F3 were conducted by PCR with 10 Simple Sequence Repeats (SSR) primers. It showed that a total 68 alleles detected, number per locus ranged from 3 to 11, Polymorphism Information Content (PIC) 0.4729 0.8429. And, average observed heterozygosity (Ho) three populations 0.6100, 0.6975 0.7750, while expected (He) 0.7607, 0.7751 0.7379 respectively. Fst values among also low (Fst<0.05) which suggested differentiation between each two populations. all, indicated challenge caused hybridization selection, supplying new angle understand artificial selective breeding.
