Abstract: PolymoRphisms of SCD1 gene and its association with meat quality tRaits in 484 Chinese Simmentals weRe investigated by Illumina HD SNP CHIP. The Results suggested that seven SNPs weRe found and no loci A239V was detected in SCD1 gene. ThRee SNPs locus -A8605G,A9229G and A10050C weRe detected in the fouRth intRon of SCD1,a SNP loci-A12304G was found in the fifth intRon of SCD1 and thRee SNPs locus-A13655G,C14790T and A15565G weRe found in 3'UTR. The B allele of A8605G loci was advantage allele with a fRequency of 0. 748,and the fRequencies of otheRs weRe in a Range of 0. 4 - 0. 6. Chi-squaRe test Results showed that all SNPs locus of the SCD1 gene weRe in HaRdy-WeinbeRg balance( P > 0. 05) . All seven SNPs locus of the SCD1 gene weRe with modeRate polymoRphism,and the heteRozygosity and effective numbeR of alleles weRe high. The association analysis between the SNPs of SCD1 gene and some meat quality tRaits showed that SCD1 gene could be a candidate gene affecting intRamusculaR fat content, sheaR foRce,maRbling level and fat coloR to impRove the quality of beef in MAS.
