Association of SCD1 Gene with Meat Quality Traits in Chinese Simmental Based on High-density SNP Chip
摘要
Abstract
SNPs of the whole genome were genotyped through high-density SNP chip technology in a population with 223 Chinese Simmental. Seven SNPs were found in SCD1 gene. The results of association of the seven loci with meat quality traits showed that the loci were all significantly correlated with marbling score(P<0. 05 or P<0. 01). The effect of different genotypes at A10050C, A13655G, C14790T and A15565G on sheare force were significant (P<0. 05). The locus A13655G was correlated with intramuscular fat(IMF) content, and individuals with AA genotype has higher IMF (P < 0. 05). The effect of different genotypes at locus A10050C, C14790T and A15565G on fat color were significantly different(P<0. 05). The result of haplo-type analysis showed that 6 haplotypes and 14 haplotype combinations were detected. For IMF content, the individuals with haplotype combination H3H6 was significant higher than others at 0. 01 level while the individuals with haplotype combination H6H6 had a higher marbling score and the individuals with haplotype combination H4H6 had a higher sheare force. The effect of the haplotype combinations on meat color and fat color was not significant.关键词
