The invention relates to an SNP (Single Nucleotide Polymorphism) molecular marker of a pig, in particular to an SNP molecular marker influencing the Landrace eye muscle area and application of the SNP molecular marker. The SNP marker is located at the 300th site from the 5'end on SEQ ID No.1, corresponds to the 6172938th site from the 5 'end on the 10 # chromosome of the international pig genome of the version 11.1, and is C or T. According to the invention, an SNP site which is located in a USH2A gene region and affects the expression activity of the USH2A gene region is identified by utilizing GWAS analysis, an SNP genotype CC individual of the site is determined to have a larger eye muscle area than a TT individual, and a dominant genotype which is beneficial to increasing the eye muscle area of the pig is selected for breeding, so that the meat production performance of the pig can be rapidly improved, and the breeding efficiency is improved. The method has guiding significance in accelerating the breedin
