Host Range, Mating Type, and Fertility of<i>Pyricularia grisea</i>from Wheat in Brazil

Abstract

Isolates of Pyricularia grisea collected from wheat in regions of Brazil were inoculated on various gramineous plants to determine their host range. A set of 42 different gramineous plants belonging to nine tribes was analyzed by plant reactions and sporulation potential. The strain from wheat infected gramineous plants of five tribes: Hordeae, Festuceae, Aveneae, Chlorideae, and Agrosteae, but not Japanese differential or Brazilian lowland and upland rice cultivars
