Abstract: 4 exons of CTSD gene from 51 Simmental×Luxi cattles were amplified and sequenced. 4 SNPs were identified at position 581,599,861 and 1128 bp of CTSD gene(NM 001166521.1) by sequencing. The effects of 4 mutations on meat quality and carcass traits were analyzed by using general linear model. The results showed that T581C polymorphism significantly associated with marbling trait(P<0.05). Genotype of BB had better marbling grade than AA and AB genotypes. Thus T581C might be a good marker for marbling traits.

Key words: cattle; CTSD gene; meat quality traits; carcass traits
