ABSTRACT Spot blotch, caused by the fungal pathogen Cochliobolus sativus, is an important disease of barley in many production areas of the world. To assess genetic diversity in this pathogen, a worldwide collection of C. sativus isolates was evaluated for virulence on barley and DNA polymorphism. Three pathotypes (0, 1, and 2) were identified among the 22 isolates tested in this study and the 36 isolates characterized previously on three barley differentials (ND5883, Bowman, and NDB112) that… CONTINUE READING
