基因组选择技术在羊育种中的应用研究

Application of genome selection technique in sheep breeding

摘要:

随着分子生物技术的发展,2001年一种新型动物育种方法——分子育种问世,此项技术弥补了传统育种的不足,具有缩短世代间隔、降低育种成本等优势。羊养殖作为畜牧产业中的重要组成部分,育种困难是当前亟须解决的难题。因此,本文综述了基因组选择的原理、算法及基因分型的方法,同时总结了基因组选择技术在羊育种方面的应用以及该技术在应用中面临的挑战,以期为之后羊育种研究提供理论参考。

Abstract:

With the development of molecular biotechnology, a new animal breeding method - molecular breeding came into being in 2001. This technology makes up for the shortcomings of traditional breeding, and has the advantages of shortening generation interval and reducing breeding cost. As an important part of animal husbandry industry, sheep breeding is an urgent problem to be solved. Therefore, this paper reviewed the principles, algorithms and genotyping methods of genome selection, and summarized the application of genome selection technology in sheep breeding and the challenges faced by this technology in the application, in order to provide theoretical reference for future sheep breeding research.
