摘要/Abstract

摘要： 近一个世纪的传统选育使家禽的各项生产性能接近表型选育极限,基因组学领域的发展成为突破这一瓶颈的新途径。自2004年第一个鸡的基因组草图发布以来,鸡、鸭、鹅等家禽的基因组参考序列在近年相继发布,且质量逐步提升。基于家禽高质量的基因组参考序列,研究学者进一步对家禽的重要性状展开了系列研究,这些研究加速了我们对家禽重要性状的认识和理解,并为在家禽基因组选择育种中应用筛选出有效的分子标记。本文就家禽的基因组参考序列研究、重要性状的基因组学研究及其应用进行综述。

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.

Key words: poultry, genomics, breeding, application
