Genetic variation of Chlamys farreri,Patinopecten yessoensis and their hybrids
摘要
Abstract
Amplified fragment length polymorphism (AFLP) technology was used to analyze the genetic variation and genetic structure among three populations of Chlamys farreri(♀), Patinopecten yessoensis(♂)and their offspring F1. In total, 315 loci were amplified with five primer pairs, and 311 of these loci were polymorphic, accounting for 98.73%. Shannon genetic diversity indices were 0.477 1±0.260 6, 0.423 9±0.277 7 and 0.548 8±0.220 9, respectively for the female parent, the male parent and F1, while Nei's gene diversities were 0.329 1±0.185 0, 0.289 7±0.195 9 and 0.382 8±0.161 2, respectively. The genetic distance between C. farreri and P. yessoensis was 0.411 6, while it was 0.131 6 between F1 and their female parents, and 0.278 0 between F1 and their male parents. The dendrograms showed that the three population gathered independently, which indicated that each population was independent. AMOVA analysis indicated that 30.47% of variance was among populations and 69.53% variance was within populations, which suggested rich genetic diversity level within populations. In all, the expression of heterosis has a correlation with the genetic variation.关键词
