Abstract: The traditional breeding in the past century has made the performance of poultry close to the limit of phenotypic selection. The development of genomics has become a new way to break through this bottleneck. Since the first chicken genome draft was published in 2004, the reference genome sequences of chicken, duck, goose, and other poultry have been published in recent years, and the quality has been gradually improved. Based on the high-quality genome reference sequences of poultry, researchers have carried out a series of further studies on important traits of poultry, which have accelerated our understanding of important traits of poultry, and screened effective molecular markers for application in genome selection breeding of poultry. In this manuscript, the reference sequence of poultry genome, the genomics of important traits and its application were reviewed.
