摘要： 多倍体植物在新开放或相对不稳定的环境中具有更强的生存能力和更大的生理生化灵活性，比二倍体祖先或近缘种更能耐受恶劣环境，在营养繁殖和多年生植物中具有明显的优势。多倍体育种是近代作物育种常用方法之一。大蒜作为我国的优势园艺作物，其多倍体研究也取得了一定的成绩。本文综述了国内外大蒜染色体多倍化技术研究的最新进展，分析了大蒜多倍体研究中存在的问题，并展望了大蒜多倍体育种技术的发展前景。

Abstract: It is the physiological and biochemical flexibility that enable polyploid plants to possess stronger tolerance and viability than the diploid progenitors or relative species in adverse enviroment，especially for the vegetatively propagated or perennial plants．Polyploid breeding is widely adopted in crop breeding strategies．Some achievements have been made in polyploid aspect for garlic（Allium sativum L.）known as the traditionally horticultural crop in China．This paper gives an overview of the new progress made in the methods of polyploidization at home and abroad，and analyzes the existing problems in polyploid garlic breeding．The development of garlic breeding technology for the years to come is also prospected.
