Transcription factors (TFs) encoded bySALL1andSALL3genes play central roles in the regulation of ovarian development in hens. The present study aimed to examine polymorphisms of these two genes in Chinese Dagu chickens, and to identify the effects of TFs on the laying performance. Among the population, two novel single‐nucleotide polymorphisms (SNPs) were identified by single‐strand conformation polymorphism (SSCP) in the amplicons of the candidate genes. The effect of the SNP (729C > A) in exon 2 ofSALL1gene on egg production at 43, 57, and 66 weeks and EW at 30 and 43 weeks were the most significant in the 360 samples (P< 0.05). Moreover, for the SNP 1014T > A (in exon 2 ofSALL3), the TT genotype was significantly correlated with higher egg production and EW (P< 0.05). Furthermore, four combined genotypes were reconstructed based on the two SNPs. The combined genotype TATT was correlated with the highest egg production at 43–66 weeks and with higher EW at 30, 43 weeks (P< 0.05). The polymorphisms of the two TFs studied are potential molecular genetic markers for chicken breeding, which might help in understanding the genetic structure of laying performance and improving these traits directly by marker‐assisted selection (MAS).
