Molecular marker related to sow reproductive traits, screening method and application

The invention relates to a molecular marker related to sow reproductive traits, a screening method and application, and relates to the technical field of pig genetic genes. The molecular marker is an SNP (Single Nucleotide Polymorphism) molecular marker and is located at the position of 96673697 bp of a pig chromosome 1 or the position of 58587289 bp of a pig chromosome 10, and a pig reference genome is Sscrofa11.1; the 96673697bp position of the pig chromosome 1 is Cgt; in the mutation site of T mutation, the 58587289bp position of the pig chromosome 10 is Cgt; the mutation site of T mutation is shown in the description. The breeding traits of sows with different genotypes of the molecular marker have extremely significant differences, sows selected and reserved according to the molecular marker can reserve sows with a high total farrowing number and a high total alive number, the breeding traits of the sows can be improved, and the farrowing performance of the sows can be improved. 本发明涉及一种与母猪繁殖性状有关的分子标记及筛选方
