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.
