一种位于猪14号染色体上与猪繁殖性状相关的SNP分子标记及应用
By detecting the SNP molecular marker C>T mutation on pig chromosome 14, pig individuals with CC or TC genotypes can be screened, solving the problems of stability and applicability of molecular markers for pig reproductive traits in existing technologies. This achieves efficient molecular marker-assisted selection and significantly improves the reproductive performance and breeding efficiency of pigs.

AI Technical Summary
The number of molecular markers used for pig reproductive traits in existing technologies is limited, and they lack stability and wide applicability, making it difficult to effectively improve reproductive performance through traditional selection breeding.
We provide molecular markers for SNPs located on pig chromosome 14, along with their primer pairs and kits, to detect C>T mutations at SNP sites, screen pig individuals with CC or TC genotypes, and increase the frequency of allele C generation by generation to achieve marker-assisted selection.
It significantly improves the reproductive performance of pigs, shortens the breeding cycle, and enhances breeding accuracy and economic benefits, especially in reproductive traits that are difficult to improve through phenotypic selection.
