Abstract
The amplified fragment length polymorphic (AFLP) technique was used to analyze the genome DNA polymorphism among 8 breeds of domestic ducks and 2 species of wild ducks. Nine of the 17 selected primers pairs gave reproducible polymorphic DNA amplification bands. The amplified bands ranged from 44 to 83 per primer pair. Of the 513 AFLP markers obtained, 498 were polymorphic. The proportion of polymorphic loci was 97.1%. The genetic distance (D) and similarity coefficients (GS) were calculated based on the polymorphic data. Between domestic ducks D ranged from 0.331 to 0.589, while between domestic ducks and the wild ducks, it ranged from 0.298 to 0.520 (vs. Anas Platyrhynchos) and from 0.316 to 0.522 (vs. A. Poecilorhyncha), respectively. The variance analysis showed no significant difference between the two groups of data, which indicated that both mallard and spot-billed ducks made contributions to domestic duck evolution. A dendrogram was constructed according to the D value.
