Construction of SNP feature library for the identification of chicken breeds.

ABSTRACT: Breed identification is an important prerequisite for the protection, development and utilization of animal genetic resources. This study developed an accurate identification strategy for chicken breeds using whole-genome sequencing data from 492 individuals belonging to 14 chicken breeds. These breeds include eight local Chinese breeds (Tibetan chicken, Chahua chicken, Daweishan chicken, Liyang chicken, Lindian chicken, Silky chicken, Dongxiang blue-shell egg chicken, and WenChang chicken), three standard chicken breeds (Rhode Island Red, Leghorn, and Light Sussex chicken), two commercial breeds (Cobb broiler and Yellow Plumage Dwarf chicken) and the Red Jungle fowl. We compared three ancestry informative marker (AIM) detection methods (Fst, I_n, and PCA-correlated SNPs) and fou
