Wheat Stripe Rust
Get the latest Wheat Stripe Rust news, research and developments covering disease outbreaks, resistant varieties, breeding, fungicide management, pathogen surveillance and crop protection. Wheat stripe rust, also known as yellow rust, is caused by Puccinia striiformis f. sp. tritici and can cause serious yield losses, particularly under cool and humid conditions.
A major focus of research is developing durable genetic resistance as the pathogen continues to evolve and new virulent races can overcome previously effective resistance genes. Breeding programmes are using germplasm screening, Yr resistance genes, quantitative trait loci, molecular markers, genome-wide association studies and genomic selection to identify and combine new sources of resistance. A 2026 study identified 77 Yr loci, including 43 potentially novel loci, from a diverse wheat panel screened against multiple pathogen isolates.
Find updates on yellow rust surveillance, disease forecasting, resistant wheat cultivars, fungicide applications, pathotype evolution and integrated disease management. In India, research institutions including ICAR have long focused on resistance breeding and strategic deployment of resistance genes, while recent research continues to identify wheat genotypes with resistance against prevalent and emerging pathotypes.
