Bacterial wilt of perennial ryegrass is caused by the pathogen Xanthomonas translucens pv. graminis. The disease triggers systemic wilting of plants, which leads to significant losses in green mass yield.

crop Perennial ryegrass,
where this is mentioned in the description.
The causative agent of bacterial wilt in the crop is the bacterium Xanthomonas translucens pv. graminis, which infects the plant's vascular system. The disease leads to physiological wilting of vegetative organs, which negatively affects the productivity of grass stands.
In perennial ryegrass breeding, research is underway to identify genetic regions responsible for resistance to this pathogen. Studies are focused on identifying quantitative trait loci (QTLs) that provide resistance to bacterial infection, although specific nomenclatural designations for individual resistance genes in commercial varieties are not currently systematized.
