In this study, researchers examined Single Nucleotide Polymorphisms (SNPs) in the exons of the Myf5, Myf6 and MyoG genes using Polymerase Chain Reaction (PCR)-Single Strand Conformation Polymorphisms (SSCP) and DNA sequencing methods in 360 individuals from 6 commercial pure lines of Sichuan Daheng meat type quality chickens. About 2 SNPs (87T>C and 96C>T) in exon 1 of Myf5, 1 SNP (154T>C) in exon 1 of MyoG and no variation in Myf6 were detected. The 96C>T SNP in Myf5 was a rare variant and was not analyzed further. The association analysis of genotypes with carcass traits revealed that the genotypes of SNP (87T>C) in Myf5 were significantly associated with Live Weight (LW), Carcass Weight (CW), Semi-Eviscerated Weight (SEW) and Eviscerated Weight (EW) (p<0.05). The SNP genotypes (154T>C) in MyoG were significantly associated with Live Weight (LW), Carcass Weight (CW), Eviscerated Weight (EW) and Breast Muscle Weight (BMW) (p<0.05). The results suggested that Myf5 and MyoG genes are potential major genes or are in close linkage disequilibrium with the QTL affecting carcass traits in this population of chickens. The 2 SNPs may potentially have use as markers for Marker-Assisted Selection (MAS) in chicken breeding. ER -
