Abstract: This study aimed to screen single nucleotide polymorphism(SNP) markers that can be used for the quality traceability of Meishan pig and Shennong pig. In this experiment, PCR-RFLP method was used to detect the polymorphism of 14 SNPs from 13 genes in Meishan pig populations and Shennong pig populations, in order to find SNPs with rich polymorphism, and finally determine the combination of SNP sites that can be used for pork traceability verification test of Meishan pig and Shennong pig by sampling again. The results showed that MMP19 gene, GRN gene, NR4A1 gene each had one SNP and PSMB10 gene had two SNPs, and the heterozygous values were all greater than 0.30, which met the requirements of meat traceability. Bar codes compiled according to 5 SNPs of MMP19, PSMB10, NR4A1 and GRN genes can be used to detect the pork quality traceability of Meishan pig and Shennong pig.

Key words: pork, traceability, single nucleotide polymorphism
