Application of molecular markers in association analysis of total number of piglets born in Changbai pig

By performing genotyping and association analysis on Landrace pigs, SNP molecular markers associated with the total litter size trait were screened, solving the problem of slow genetic progress in the total litter size of sows and improving breeding efficiency.

Abstract

The application discloses a SNP molecular marker related to a total number of piglets character of a Changbai pig and application thereof, a SNP site with a login number of rs322407989 is significantly related to the total number of piglets character, and the SNP site is located at a base at position 92518039 of a chromosome 7 (version 11.1 of a pig genome), reference is made to an Ensembl database, nucleotide sequences of 50 bp upstream and downstream of a fragment with the login number of rs322407989 are obtained, the nucleotide sequences are shown in a sequence table SEQ ID NO. 1 or 2, a polymorphism site is G or A, compared with an individual with a genotype of GG, the Changbai pig has a higher total number of piglets when the genotype is AG.
