Abstract: This study was designed to investigate the correlation between SNP of MyoG gene and growth traits in Luning chicken.The 5'polymorphism of MyoG gene were detected by PCR-SSCP and DNA sequencing technology.As a result,four SNPs (A153G,A267G,A446G and C612T) were found in MyoG gene.Analysis showed that the mutation in 153 bp of MyoG gene exhibited three genotypes (AA,AG and GG),individuals with AA genotype had significant effect on liver weight than those with AG and GG genotypes (P <0.05).The mutation in 446 bp of MyoG gene performed three genotypes (AA,AG and GG),compared with individuals with GG genotype,those with AA and AG genotypes had significant effect on slaughter percentage (P <0.05),and with AA Genotype,those with AG and GG genotypes had significant effect on breast muscle percentage (P <0.05).It could be stated that MyoG gene showed a significant effect on Luning chicken growth traits.So MyoG gene could be served as a candidate gene in growth traits of Luning chicken for further study.
