Abstract: The Mx gene in Anka chicken was analyzed with mismatch PCR-RFLP method, the results showed that M2032 locus of Mx gene digested by restriction endonuclease RsaⅠcould be divided into three kinds of genotypes, AA, GG and AG. The frequencies of these genotypes were 0.232, 0.681 and 0.087, respectively. The frequency of resistance allele A was 0.572. The result of Chi Square test indicated that the frequencies of Mx gene digested by RsaⅠ were significantly deviated from Hardy-Weinberg equilibrium in this study. The correlation between the three genotypes with some commercial traits was analyzed, the results showed that the body weight of different developmental stage, body size mainly slaughter traits and meat quality of the individuals were with resistant genotype AA were not significant different with those individuals with AG and GG genotypes in Anka chicken, which indicated that M2032 locus of Mx gene had no significantly negative genetic effects on commercial traits in Anka chicken.
