豌豆白粉病研究进展

Research progress in powdery mildew in peas

豌豆白粉病是由气传性豌豆白粉菌(Erysiphe pisi)引起的病害。近年来白粉病对于豌豆的危害日趋严重,直接导致豌豆大面积减产,鲜荚和籽粒的数量和品质下降,从数量和质量上严重制约豌豆生产,已成为世界性重要病害。本文对豌豆白粉病病原菌、病害症状及其侵染发生规律进行了阐述。并对抗病性鉴定、抗性机理、种质资源、防治策略和分子标记等国内外新近研究进展进行了综述,并探讨了豌豆白粉病抗性研究的方向。

Pea powdery mildew is an air-borne disease of pea. In recent years, powdery mildew has become increasingly serious hazards worldwide and caused severe losses both in quality and quantity of fresh pods as well as dry seeds. The following topics are discussed such as pathogen, symptoms and invading rules. The resistance mechanism, control strategies and molecular markers were reviewed as well. Further research direction of pea powdery mildew resistance was also explored.
