Major SNP (single nucleotide polymorphism) marker influencing growth traits of pigs and application thereof in genetic improvement of productivity of breeding pigs

The invention provides a major SNP (single nucleotide polymorphism) marker influencing the growth traits of pigs. The SNP marker is located at a nucleotide sequence of an HMGA1 gene of a pig chromosome 7, a locus of the SNP marker is the nucleotide mutation of C857-G857 with an SEQ ID NO:1 sequence labeling position of 857, corresponding to a 34983991st nucleotide locus C> on chromosome 7 in a reference sequence in an international pig genome version 10.2, G mutation, or one of seven other loci completely linked with the locus. The invention also provides the application of the SNP marker in the genetic improvement of growth traits of breeding pigs, and provides the application of an SNP molecular marker with a linkage disequilibrium degree (r2) with the SNP marker of greater than 0.8 in the genetic improvement of growth traits of breeding pigs. The growth traits include one or more of the length and height of a living body of a pig, carcass length, carcass weight, daily gain and head weight. According to the invention, the breeding process of breeding pigs can be accelerated, the productivity of breeding pigs can be effectively improved, and remarkable economic benefits can be obtained.

The invention relates to an identification method of PPARD major gene, establishment of a molecular breeding method and application in the genetic improvement of breeding pigs. In the invention, by adopting the white Duroc * Erhualian Intercross and the Chinese and exotic breeding pigs of distant population, the whole-genome scan and linkage mapping, the IBD fine mapping of the target region based on a high-density SNP mark and the selection effect analysis of the distant population are carried out, and then the major gene, i.e., PPARD for deciding the traits of pig ears, fat deposition, weight of pig head and carcass traits, and the mutation site of key cause, i.e., G32E are identified. The sites are detected by the modern molecular biotechnology; by adopting the gene-assisted selection method, the beneficial gene-typed individuals are selected for the breeding pigs, thereby the breeding improvement efficiency of the traits of pig ears, fat deposition, weight of pig head and carcass traits are remarkably improved. The invention further discloses an identification course of the gene and the cause mutation site and a method for breeding the traits of pig ears, fat deposition, weight of pig head and carcass traits by using the gene marker of the invention.
