摘　　要：基因组选择(genomic selection,GS)已经作为新一代畜禽遗传评估方法应用于奶牛育种中,并取得了显著成效。随着羊参考基因组的不断完善,以及不同密度SNP芯片的推出和商业化推广,新西兰、澳大利亚、法国等相继将基因组选择应用到羊育种中,揭开了羊育种的新时代。本研究总结了国内外羊基因组选择的研究现状、影响因素、优势以及存在问题和展望,以期为中国羊开展基因组选择育种提供参考。As a new genetic evaluation method in livestock and poultry,genomic selection(GS)has been applied in dairy cattle breeding and gained remarkable success.With the improvement of reference genomes of sheep and goats and the availability of SNP chips with different densities,the application of GS in sheep and goats has also being undertaken in New Zealand,Australia,France,etc..In this review,we summarized the current status of application of GS,factors affecting the accuracy of GEBVs and the advantages of GS in sheep and goat breeding.Moreover,we also discussed potential problems,aiming to provide a reference for carrying out GS in sheep and goat breeding in China.
