摘　　要：紫花苜蓿(Medicago sativa)无论从种植面积,还是在畜牧业中的地位,都是我国最主要的牧草。苜蓿黄萎病是世界范围内危害苜蓿的毁灭性病害,我国将其列为对外检疫对象。其病原曾被鉴定为黑白轮枝孢(Verticillium albo-atrum),2011年又被重新描述为苜蓿轮枝孢(Verticillium alfalfae)。然而,我国对外检疫名单中苜蓿黄萎病的病原至今仍为黑白轮枝孢,这无疑给检疫工作带来了困难。在我国,苜蓿黄萎病于2016年在甘肃省张掖市发生,经调查发现该病害目前已广泛分布于我国最主要的苜蓿商品草生产区之一——河西走廊。为了使植物病理学工作者、牧草管理人员和栽培人员多关注这种危险性病害,以加强综合防控技术的研究,本文综述了苜蓿黄萎病在国内外的研究进展,包括病原种类、分布、侵染循环、发生规律、造成的危害、快速检测方法,以及防治技术,并对未来研究方向提出了展望。Alfalfa(Medicago sativa L.)is the most important pasture crop in China in terms of its planting area and status in animal husbandry.Verticillium wilt is a devastating disease worldwide,and China has listed it as an import plant quarantine object.The causal agent was previously known as Verticillium albo-atrum and renamed Verticillium alfalfae in 2011.However,on the list of quarantine diseases for the plants imported to China,the causal organism of alfalfa Verticillium wilt was still designated as V.albo-atrum.This undoubtedly brings much confusion to the quarantine work.In China,the disease was ever found in Zhangye City,Gansu Province,in 2016,and has now been widely distributed in the Hexi Corridor,the most important commercial alfalfa produc-tion area in China.It is vital to encourage relevant researchers to pay more attention to this dangerous disease so as to strengthen integrated control measures of the disease.This paper reviews research progress on Verticillium wilt of alfalfa,including the causal pathogen species,distribution,infection cycle and management measures,and suggests future research directions.
