Six single nucleotide polymorphisms in adipocyte fatty acid-binding protein (A-FABP) gene in Beijing ducks PCR-SSCP was applied to analyze the polymorphisms of A-FABP gene in 4 lines of Beijing ducks (n = 400). The results showed that six SNPs were found in intron 3. There were no polymorphisms found in exon 3 or exon 4. The discovered SNPs were deposited in GenBank (Acc. No.: EU306611 and EU306610). The frequencies of haplotypes A/B in the Z4, Z2, Cherry Valley, Z4 × Z2 populations were 0.745/0.255, 0.764/0.236, 0.552/0.448, 0.672/0.328, respectively. The linkage disequilibrium was stated. The above described SNPs of A-FABP gene allow the incoming association analysis.
