摘　　要：紫花苜蓿是广泛种植的多年生豆科牧草,耐寒性是其安全越冬的关键。本文分析了苜蓿的耐寒性,阐述了苜蓿对低温适应的形态变化及生理遗传调控机制;综述了苜蓿耐寒育种的研究进展,包括常规育种、分子标记辅助育种和基因工程育种在耐寒苜蓿研究上取得的研究成果,为今后苜蓿耐寒性研究及苜蓿耐寒育种提供了理论依据。Alfalfa is a perennial legume which is widely cultivated all over the world and cold resistance is of great importance for it to survive in winter. Recent studies in the cold tolerance of alfalfa analyzed the physiological changes and genetic regulatory mechanism response to cold condition. In this review article, we focus on the advances in alfalfa breeding for cold tolerance including conventional breeding, molecular marker-assisted breeding and genetic engineering breeding, which provides a theoretical basis for the further research on cold tolerance of alfalfa and breeding of alfalfa.
