The term Landrace pig or Landrace swine refers to any of a group of standardized breeds of domestic pig, and in this context the word Landrace is typically capitalized. The original breed by this name was the Danish Landrace pig, from which the others were derived through development and crossbreeding. The breed was so-named because the foundation stock of the Danish Landrace were specimens from the local, free-breeding, non-pedigreed stock of swine, i.e. the regional landrace native to Denmark. The modern breeds are not themselves landraces, since they are formal breeds maintained through selective breeding rather than natural selection. The establishment and spread of the Danish breed gave the word landrace to the English language (it had already existed in Danish, German, Dutch and some other Germanic languages). Sources from the mid-20th century often mean the Danish Landrace swine in particular when referring to "Landrace" pigs, as most of the others had not been developed yet.
A snp marker affecting pig purine base content and application thereof
The present application relates to the field of molecular markers and animal genetic breeding technology, and particularly relates to a SNP marker affecting pig purine base content and application thereof. Based on three test pig populations of American purebred Landrace, American purebred Large White and American purebred Duroc, the present application uses pig whole genome resequencing and GWAS analysis to research and determine 15 SNP markers significantly affecting pig purine base content. By selecting the advantageous alleles of the above SNP markers, the frequency of the advantageous alleles can be increased generation by generation, the corresponding purine content can be reduced or increased, the progress of pig genetic improvement can be accelerated, and the economic benefits of pig breeding can be effectively improved.

SNP (Single Nucleotide Polymorphism) marker primer pair related to pig multirib character and application of SNP marker primer pair
PendingCN121826162AMicrobiological testing/measurementFood processingBiotechnologyWhole Genome Association Analysis
The invention provides an SNP (Single Nucleotide Polymorphism) marker primer pair related to pig multirib traits and application of the SNP marker primer pair. The SNP site is a nucleotide site of chromosome 7 rs701714758 of a reference sequence of an international pig genome version 11.1, has G / A polymorphism, is located in a protein coding region of an ABCD4 gene, and is remarkably associated with rib number characters of Duroc pigs, landrace pigs, large white pigs and Pietrain pigs through verification of whole genome association analysis and meta analysis. The invention further provides a primer pair for detecting the SNP marker, an upstream primer of the primer pair is SEQ ID NO: 2, and a downstream primer of the primer pair is SEQ ID NO: 3. The SNP marker can be applied to marker-assisted selection and whole genome selection of rib number characters of multiple varieties of pigs, can accurately screen a multi-rib number pig group, improves character prediction accuracy, increases pork and rib row yield, meets consumption demands, and has both social and economic benefits.

A SNP marker affecting the total flavor nucleotide content in pigs and its application
This invention relates to the fields of molecular markers and animal genetic breeding technology, and particularly to a SNP marker affecting the total flavor nucleotide content in pigs and its application. Based on three experimental pig populations—purebred American Landrace, purebred American Large White, and purebred American Duroc—this invention employs whole-genome resequencing and GWAS analysis to study and identify nine SNP markers associated with total flavor nucleotides. By optimizing the dominant alleles of these SNPs, the frequency of dominant alleles can be increased generation by generation, thereby increasing the total flavor nucleotide content, improving pork quality, accelerating the progress of pig genetic improvement, and effectively improving the economic benefits of pig breeding.

A rs338618851 site snp molecular marker related to pork production efficiency of pigs and application thereof
The application discloses a SNP molecular marker of a site rs338618851 related to pork production efficiency of pigs and application. The genetic marker is cloned from a 93991071 site of a chromosome 6 of pigs. American Landrace pigs are selected as test materials, whole genome DNA is extracted from blood of the pigs, and a primer is designed according to a pig genome sequence NC_010448.4 published in an NCBI database. A base substitution of T or C exists at a 172th position of a primer amplification sequence, the substitution causes polymorphism at the position. The SNP site is typed through a direct sequencing technology, and correlation analysis shows that, compared with other gene individuals, a TT genotype individual at the 172th position is large in birth weight, large in eye muscle area and short in time to reach 100 kg at a certain age. The application provides a new marker for molecular breeding of pork production traits of pigs.

A SNP marker affecting porcine inosine content and its application
This invention relates to the fields of molecular markers and animal genetic breeding technology, and particularly to a SNP marker that affects porcine inosine content and its application. Based on purebred American Landrace, purebred American Large White, and purebred American Duroc pigs, this invention studies and identifies 10 SNP molecular markers closely related to porcine inosine content. By optimizing the dominant alleles of these SNPs, the frequency of dominant alleles can be increased generation by generation, reducing inosine content, accelerating the progress of pig genetic improvement, and thus effectively improving the economic benefits of pig breeding.

A snp molecular marker related to pork yield efficiency of pigs and application thereof
The present application belongs to the field of molecular biological technology and molecular marker technology, and relates to a SNP molecular marker related to pork yield efficiency of pigs and application thereof, which is from the 93707553th site of chromosome 15 of pigs. Large white pigs and long white pigs are selected as test materials, whole genome DNA is extracted from blood of the pigs, and primers are designed according to the pig genome sequence (NC_010457.5) published by NCBI database. There is a base substitution of A or G at the 306th site, resulting in polymorphism.
