Group of molecular markers related to properties of pH color, meat color, backfat thickness and intramuscular fat content of pork

The invention discloses a group of molecular markers related to pork pH color, pork color, backfat thickness and intramuscular fat content characters. Specifically, on an HS6ST3 gene on a chromosome 11, a 66186813 nucleotide is a G/C gene, and when the gene is a GG genotype, the pH value and the meat color b value of the pork are significantly higher than those of other genotypes; the 66189600 nucleotide is a C/T gene, and when the gene is a TT genotype, the backfat thickness and intramuscular fat content of the pork are obviously higher than those of other genotypes; the 66190132 nucleotide is a C/T gene, and when the gene is a TT genotype, the backfat thickness and intramuscular fat content of the pork are obviously higher than those of other genotypes; a CC gene is arranged at a 66191323bp nucleotide, and the intramuscular fat content of the pig is higher than that of individuals with other genes; a CG gene is arranged at a 66191306bp nucleotide, and the intramuscular fat content of the pig is higher than
