Morphological and Pathogenic Variability in Bipolaris sorokiniana Causing Spot Blotch in Wheat (Triticum aestivum, T. durum, T. dicoccum) in India

Abstract

Spot blotch in wheat (Bread wheat Triticum aestivum L.emend Fiori & Paol., durum wheat T. durum Derf, Khapli wheat T. dicoccum Schubl.) is mainly caused by Bipolaris sorokiniana Boerma (Sacc.) in India and neighbouring south Asian countries and capable of causing losses in yield up to 50 % in susceptible varieties as well as results poor grain quality.
