摘　　要：综述了我国苜蓿育种取得的成就及展望。到目前为止,已审定登记育成新品种23个,国外引进品种15个,野生驯化品种3个,整理地方品种19个。育成品种具有抗寒、抗病、耐盐、耐牧、高产、早熟等特点。我国苜蓿育种大多采用常规育种技术,生物技术应用相对较少。苜蓿育种工作存在的主要问题有:育成品种少,抗性育种进程缓慢,育种原始材料较少,育种技术单一;提出改进苜蓿育种方法、培育特色品种、加强苜蓿种质资源保护与利用是缩小我国与国外苜蓿育种进程的有效途径。The achievements and prospect of alfalfa breeding in China were related in this paper. 23 cultivars were bred, 15 cuhivars were introduced into china from abroad,3 wild strains were planted, and 19 local varieties were registered. The bred strains had the characteristic with cold, disease, salt and grazing, high-yielding, early ma- turing,etc. Mostly conventional breeding techniques at alfalfa breeding were adopted at home. Biotechnology appli- cation was relatively scarce. The mostly problems were a little breeding cultivars, slow process of fastness breeding, less raw materials, singleness and lag technology at alfalfa breeding. The paper put forward the effective approaches that narrowed alfalfa breeding process, and reduced disparities among home and abroad by improving alfalfa breed- ing methods,breeding special cultivars,intensifying the alfalfa germplasm resources protection and using.
