Genome‐wide association study reveals novel loci associated with fat‐deposition and meat‐quality traits in Pekin ducks

1 month ago   |   By Animal Genetics

Summary
Meat‐quality traits play an essential role in meat poultry production. To determine the genetic mechanisms of meat quality in Pekin ducks, we performed a large‐scale GWAS to identify quantitative trait loci affecting meat quality in Pekin ducks. We measured 10 traits in 542 Pekin ducks and genotyped each duck using genotyping‐by‐sequencing. The genetic parameters (genomic heritability, genetic correlation) for 10 meat‐quality related traits were evaluated. Based on the large genotype-phenotype dataset, we performed GWASs for all of these traits. A total of 33 significant QTL across...
