Genomic insights into pigeon breeding: GWAS for economic traits and the development of a high-throughput liquid phase array chip.

ABSTRACT: Due to the monogamous mating system and late maturity of pigeons, their breeding cycle is longer compared to that of other poultry species, which has hindered the optimization of growth traits and meat quality. While traditional breeding methods are commonly used, they lack precision and are time-consuming. This study integrates phenotypic data from Tarim pigeons and White King pigeons with genomic information, using genome-wide association analysis (GWAS) to identify genetic markers associated with key economic traits, thereby accelerating the breeding process. The results reveal significant correlations between body type characteristics (e.g., live weight and chest depth) and carcass traits, supporting their use as indirect selection criteria. GWAS identified several candidate genes, inc
