摘　　要：根肿病是原生动物界根肿菌门根肿菌属芸薹根肿菌(PlasmodiophorabrassicaeWor.)侵染引起,并专性危害十字花科作物的一种传染性强的土传病害。近些年来,加拿大和我国油菜的安全生产均受到根肿病的严重威胁。本文简要介绍了根肿菌的生物学特性、分类及主要防治途径,重点总结了在根肿病抗性资源发掘、抗病基因遗传定位和克隆以及抗病育种等方面的进展,分析了目前我国油菜根肿病综合防控过程中存在的主要问题,并探讨与展望了相应的对策,旨在为油菜抗根肿病遗传育种的高效顺利开展提供技术支持,进而保障油菜产业的可持续发展。Clubroot is one of the most serious soil-borne diseases caused by Plasmodiophora brassicae Woronin in oilseed rape(Brassica napus).Being a major oil crop,the safe production for oilseed rape both in Canada and China is now facing severe threat from clubroot disease in recent years.In this review,after briefly introducing the biological features of this pathogen,the root symptoms after infection,pathogen-type differentiation,strategies usually employed in disease controlling process,and a strategy based on genetic breeding are highlighted in clubroot disease comprehensive control for oilseed rape;furthermore,for sustainable development of oilseed rape industry by avoiding damages caused by clubroot disease,major problems faced are pointed out and some prospects are addressed accordingly.
