Poa pratensis is a widely used cool-season turfgrass, but it is susceptible to the infestation of Blumeria graminis f. sp. Poae (BGP), which greatly affects the quality and service life of turf. The most economical, environmentally friendly and effective way to prevent powdery mildew is to select and breed good resistant species. By studying the powdery mildew resistance mechanism of different resistant P. pratensis materials, we can provide theoretical support and important foundation for the excavation of powdery mildew resistance germplasm resources and molecular breeding of resistance.
