Conteúdo:	Forty isolates of Pyrenophora trichostoma from the Central Plains of North America were separated into 12 races for leaf spotting virulence on six wheat cultivars. The wheats were separated into six differentials for resistance. BH1146 spring wheat from Brazil was resistant to the largest number of races. These isolates and cultivars are the basis for a system for the determination of genes for virulence and resistance. Larker barley was resistant to all 40 isolates. The fungus also caused "black point" of wheat seed and brown spots on glumes and awns.
