Abstract: Based on gene pooling and sequencing, a new SNPs was found on the bovine MyoD1 gene, its transition C-T leads to a reaplacement of glicine with serine. Polymorphism and relationship with the carcass traits was analysised by PCR-RFLP in different populations. The transition of this locus fit in with Hardy-Weinberg equilibrium in Chinese-simmental cattle and Luxi cattle, but not in Qinchuan cattle. Statistical analysis revealed higher value in back fat and thickness of thigh (P<0.05), not in average daily growth, yield of carcass, intramuscular fat, marbling and yenderness.
