摘　　要：基因组选择(Genomic Selection,GS)技术是利用覆盖全基因组与性状相连锁的标记信息,通过标记效应的求解和加和,得到个体基因组估计育种值(GEBV),从而达到对畜禽个体进行准确选择的目的。该技术率先在奶牛育种中得到广泛应用。在猪育种中,以杜洛克猪为代表,基因组选择技术的应用可以达到早期选择和提高选择准确性的效果,然而对于母系猪(以繁殖性状选择为主),并没有经济有效的利用方案。本文首先对基因组选择应用过程中关键问题进行讨论;其次简要介绍了基因组选择技术在父系猪中的应用情况;最后围绕我国母系猪育种的现状,探讨基因组选择技术在母系猪中如何应用。The Genomic Selection（GS） technology takes the advantage of the marker information, which cover the genome and connect to the economic traits, to calculate the total effects and selection individuals on the basis of the genomic estimated breeding value（GEBV）. GS was first widespread used in dairy cattle, while in pigs, the benefit of early selection and increasing in the selection accuracy were first emerged in Duroc pigs. However, in maternal pigs, the genetic breeding program is more complex. To find out the problem, this paper firstly discussed the key issues in the application of genomic selection and then introduced the application in Duroc pigs. Finally, how to combine the genomic seletion to the present pig breeding program in maternal pigs was mainly discussed.
