AB  - The <I>MyoD</I> gene family has been proposed to profoundly modulate muscle development and carcass performance in farm animals. In this study, researchers examined Single Nucleotide Polymorphisms (SNPs) in the exons of the <I>Myf5</I>, <I>Myf6</I> and <I>MyoG</I> 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&gt;C and 96C&gt;T) in exon 1 of Myf5, 1 SNP (154T&gt;C) in exon 1 of MyoG and no variation in Myf6 were detected. The 96C&gt;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&gt;C) in Myf5 were significantly associated with Live Weight (LW), Carcass Weight (CW), Semi-Eviscerated Weight (SEW) and Eviscerated Weight (EW) (p&lt;0.05). The SNP genotypes (154T&gt;C) in MyoG were significantly associated with Live Weight (LW), Carcass Weight (CW), Eviscerated Weight (EW) and Breast Muscle Weight (BMW) (p&lt;0.05). The results suggested that <I>Myf5</I> and <I>MyoG</I> 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.
