Diseases

Rust of Italian Ryegrass

Lolium multiflorum Lam. ssp. italicum (A. Br.) Volkart

The main types of rust affecting Italian ryegrass are crown rust, caused by Puccinia coronata, and stem rust, caused by Puccinia graminis ssp. graminicola. These diseases significantly reduce forage yield and seed quality.

In the reference 70 varieties crop Italian ryegrass, where this is mentioned in the description.

Crown rust manifests primarily on leaf blades and is one of the most damaging foliar diseases of Italian ryegrass. Stem rust affects leaf sheaths, stems, and spikes, including glumes and the rachis, which is particularly critical for seed crops.

Genetic control of resistance to both rust types is based on quantitative trait loci (QTL). Breeding research involves the introgression of resistance genes from other species, such as meadow fescue; however, in variety descriptions, resistance is more often indicated by a general rating on a scale of 1 to 9.
