牧草白粉病的研究进展

Research Progress in Powdery Mildew of Forage

白粉病是由白粉菌引起的植物真菌病害,是牧草生产中常见的叶部病害之一,直接影响牧草的产量和品质,进而影响牧草产业乃至畜牧业的发展。文章综述了国内外牧草白粉病的病原菌、发病症状、发病规律、抗病机制、综合防治措施及牧草抗病基因相关研究现状,为我国牧草白粉病抗性机理深入研究、抗病新基因和抗源的发掘以及未来抗性育种工作的开展提供理论参考。

Powdery mildew is a fungal disease of plant caused by Erysiphepisi,Erysiphetrifolii,Blumeriagraminis and so on.It’s one of the common leaf disease in forage production,directly affects the yield and quality of forage,and then influences the development of forage industry and even animal husbandry.This study summarized the relevant research progress of the pathogens,symptoms,occurrence regularity,resistance mechanism,comprehensive prevention and control measures,and resistance gene in powdery mildew of foreign and domestic forage,which provided a theoretical reference for the further study on resistance mechanism,discover the new resistance gene and resistance sources,also the future development of resistance breeding in powdery mildew of grass in China.
