| Abstract: | PCR-SSCP and DNA sequencing technology were used to investigate the polymorphism of PRKAG2 gene in the Peking duck population with 334 birds.One SNP (A>G) of PRKAG2 gene was detected, which located at the 3'-untranslating region of PRKAG2 gene, there were three genotypes:AA, AB and BB, and AA genotype was the dominant genotype.It had extremely significant association with weight of 18 days old and chest width (P<0.01), and had significant association with keel length (P<0.05).So this polymorphic locus might serve as a molecular marker for Peking duck selection, and could provide references for improvement of duck performance. |
