Wheat leaf rust (''Puccinia triticina'') is a fungal disease that affects wheat, barley, rye stems, leaves and grains. In temperate zones it is destructive on winter wheat because the pathogen overwinters. Infections can lead up to 20% Crop yield, yield loss, which is exacerbated by dying leaves, which fertilize the fungus. The pathogen is a ''Puccinia'' Rust (fungus), rust fungus. It is the most prevalent of all the wheat rust diseases, occurring in most wheat-growing regions. It causes serious epidemics in North America, Mexico and South America and is a devastating seasonal disease in India. ''P. triticina'' is heteroecious, requiring two distinct hosts (alternate hosts). Host resistance Plant breeders have tried to improve yield quantities in crops like wheat from the earliest times. In recent years, breeding for resistance against disease proved to be as important for total wheat production as breeding for increase in yield. The use of a single resistance gene against var ...
