摘　　要：综述了扁蓿豆(Medicago ruthenica)抗旱性、耐盐性、抗寒性和抗病虫等四方面的研究工作进展,包括植物学特性、种子特性、物候期及根、茎、叶的生长发育、利用价值及分布和抗逆性方面的研究概况。并针对扁蓿豆研究存在的问题,提出今后研究应当集中在扁蓿豆的适应区域、抗逆基因的筛选、荚果开裂问题以及进一步的建立栽培草地等方面,以期对我国扁蓿豆种质资源的收集、保存、开发利用、新品种选育及北方生态建设提供理论依据。The research progresses of drought,cold,disease and pest resistance,and salt tolerance of Medicago ruthenica were reviewed in this study in the view of botanical characteristic,seed characteristic,phenology and growth of root and shoot,utilization value and distribution.To solve the problems in the development of M.ruthenica,this study proposed some countermeasures,including that regional adaptation,resistance genes,pod cracking,and establishment pasture,which would provide the theoretical basis for collection,preservation,development,utilization,new breeding of M.ruthenica germplasm resources and ecological restoration in the north China.
