Global status of stripe rust: a review of historical and current threats

Abstract

Stripe rust, caused by Puccinia striiformis, has been an important disease of wheat, barley, rye, triticale and certain graminaceous hosts for centuries. The significance of the disease on cultivated cereals has waxed and waned according to the vagaries of climate, inoculum levels and susceptible varieties. A progressive understanding of pathogen biology has revealed levels of specialisation between and within host groups, and these had varying impacts on the hosts concerned. The most economically important form is P. striiformis f. sp. tritici (Pst), the causal pathogen of stripe (yellow) rust of wheat, which is the major focus of this paper. The recent discovery of the perfect stage of Pst on Berberis spp. will encourage further work to uncover the potential importance of the sexual stage in pathogen biology in regions where Berberis spp. occur. A review of the evolution of pathotypes within Pst over the past 50 years reveals recurrent

Screening For Resistance Against Rust Diseases In Advanced Wheat (Triticum Aestivum L.) Genotypes

“…tritici) is important biotic factor limiting wheat (Triticum aestivum L.) yield in the country and globally. [23][24][25] Severe impact imposed by this foliar disease in terms of yield reduction ranging from 10 to 70% has mold research into its vigorous virulence as indispensable for sustainable control. 24,26 Due to wider spread of the disease, it causes 30 to 100% yield losses.…”
