摘要: 为筛选可用于梅山猪和申农猪肉质溯源的SNP位点标记,采用PCR-RFLP方法检测13个基因在梅山猪和申农猪群体内14个SNP位点的多态性,以期寻找多态性丰富的SNP位点,通过再次采集样品,进行溯源验证试验,最终确定可用于梅山猪和申农猪肉溯源的SNP位点组合。结果表明:MMP19基因、GRN基因、NR4A1基因的SNP位点和PSMB10基因的2个SNP位点杂合度(H值)均大于0.30,符合肉质溯源要求。可根据MMP19、PSMB10、NR4A1和GRN 4个基因共5个SNP位点编制用于检测梅山猪和申农猪肉质溯源的条形码。

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
