Resumo: Ninety-six monoconidial isolates of H. sativum were obtained from 41 municipal regions comprising five different states and as many as 51 different cultivars. Initially, 45 out of 96 isolates were tested against 40 wheat cultivars in the seedling stage; and based on the reaction pattern, a set of thirteen differential wheat cultivars was established. This set of differentials was further used to test the rest of the 51 isolates and a total of 32 different races were identified. The identified races were given serial numbers. Twenty-three races were identified from Paraná, 4 from São Paulo, 3 from Rio Grande do Sul, 1 from Mato Grosso and 1 from Brasilia, DF. Race 9 was most predominant in the states of Paraná, São Paulo and Rio Grande do Sul.

Inicialmente, dum total de 96 isolados 45 foram testados em 40 cultivares de trigo na fase de plântulas, e, baseado no tipo de reação, estabeleceu-se um conjunto de treze cultivares diferenciais. Tal conjunto foi posteriormente usado para testar os restantes 51 isolados e permitiu identificar, um total de 32 raças diferentes. Estas raças identificadas foram designadas por sequência numérica. No Paraná, detectaram-se 23 raças, em São Paulo 4, no Rio Grande do Sul 3, Mato Grosso 1 e finalmente para DF. -Brasilia 1 (uma). A Raça 9 foi predominante nos Estados do Paraná, São Paulo e Rio Grande do Sul.  Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMehta, Y.
