The Gushi-Anka F2 chicken resource population was established by the Henan Innovative Engineering Research Center of Poultry Germplasm Resource for genomic studies. The F2 resource population consisted of 4 cross-bred families (Anka-cocks mated with Gushi-hens) and 3 reciprocal families (Gushi-cocks mated with Anka-hens), and a total of 860 F2 chickens were finally generated. In total, 860 chickens from a Gushi-Anka F2 resource population were phenotyped for 68 growth and carcass traits, and 768 samples were genotyped based on the genotyping-by-sequencing (GBS) method. Finally, 734 chickens and 321 314 SNPs remained after quality control and removal of the sex chromosomes, and these data were used to carry out a GWAS analysis.
