The invention relates to a method for breeding a new variety of Sichuan rural black pigs. Belongs to the technical field of breeding and breeding. The method includes the steps that Duroc pigs are used as male parents, Tibetan pigs are used as female parents, and grading hybridization is carried out until F4 generation hybridization is achieved; crossbreeding the F4-generation boars and the F4-generation sows to establish a zero-generation basic pig
herd; carrying out closed breeding on the zero-generation basic swinery, and carrying out breeding on each generation until the
fifth generation; wherein the breeding mode of each generation comprises the following steps: breeding the pig individuals of the generation based on the numerical value of the BLUP comprehensive selection index of the individual, carrying out hair color SNP locus
genotype detection on the pig individuals of the generation through a Snapshot technology, and rejecting the pig individuals with black heterozygous genotypes in the pig
herd; and determining the pig individuals of the
fifth generation as the new male parent variety of the Sichuan-rural black pigs. As a male parent, the Sichuan rural black pigs bred by the method have the advantages of pure
black hair color, excellent meat quality, high production efficiency and the like.
