Abstract

Research on the identity of genes and their relationship with traits of economic importance in chickens could assist in the selection of poultry. In this study, an F2 resource population of Gushi chickens crossed with Anka broilers was used to detect single-nucleotide polymorphisms (SNPs) in the flanking region of the ASB15 gene by DNA sequencing and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). One SNP of -1271 C>T in 5' flanking region of the chicken ASB15 gene and two SNPs of the 10618 A>G and 10716 G>A in 3' flanking region were identified. Furthermore, the 10618 A>G and 10716 G>A in 3' flanking region were in complete linkage. Association analysis results showed that -1271 C>T was not associated with performance traits, while the 10618 A>G and 10716 G>A were significantly associated with BW2, 4, 6, 8, 10, 12, SL12, CD8, CW4, 8, 12, BSL4, 8, 12, and SEW, EW, WW, BMW, LW, CW, SFT. Our results suggest that the ASB15 gene profoundly affects chicken performance traits.
