SNP (Single Nucleotide Polymorphism) molecular marker related to eye muscle area of large white pig and application of SNP molecular marker

The invention belongs to the technical field of molecular biotechnology and molecular markers, and particularly relates to an SNP (Single Nucleotide Polymorphism) molecular marker related to the eye muscle area of a large white pig and application. An SNP site of the SNP molecular marker related to the area of the eye muscle of the large white pig corresponds to Agt at the 33228254bp position on a No.16 chromosome of an international pig reference genome version 11.1; c mutation, and the polymorphism of the basic group at the site affects the eye muscle area character. According to the invention, the difficulty in genetic improvement of the pig eye muscle area is solved by means of molecular breeding, and by optimizing the dominant alleles of the SNP, the frequency of the dominant alleles can be increased generation by generation, the pig eye muscle area and the lean meat percentage can be improved, and the progress of genetic improvement of pigs can be accelerated, so that the economic benefit of breeding of
