frequência na região Centro-Oeste do Brasil e pode, sob condições de alta temperatura e alta umidade, causar sérios danos à cultura. O uso de cultivares resistentes ao patógeno é recomendado, porém são poucas as disponíveis no mercado. Este trabalho foi realizado visando avaliar a reação de doze cultivares comerciais de soja inoculados com C. cassiicola, em casa de vegetação e no campo. A severidade foi avaliada utilizando escala diagramática de severidade da mancha-alvo. As cultivares menos suscetíveis ao patógeno na casa de vegetação foram BRSGO 7960 e BRS Sambaíba e as mais suscetíveis foram BMX Potência RR e M-SOY 7908 RR. No campo, as cultivares menos suscetíveis foram M-SOY 8866, M-SOY 7908 RR e BMX Potência RR e as mais suscetíveis foram BRSGO 8360 e BRS Tracajá. Palavras-chave: Glycine max, mancha-alvo, resistência genética. ABSTRACT Reaction of soybean cultivars to Corynespora cassiicolaThe fungus Corynespora cassiicola, the causal agent of soybean target spot, frequently occurs in the Brazilian midwestern region. Under favorable climate conditions it can cause serious damage to this crop. The use of resistant cultivars is recommended although there are only a few available in the market. This investigation was carried out to evaluate the reaction of twelve soybean commercial cultivars to C. cassiicola. Severity was evaluated using a diagrammatic scale of target spot. The less susceptible cultivars in greenhouse were BRSGO 7960 and BRS Sambaíba and the most susceptible were BMX Potencia RR and M-SOY 7908 RR. In the field, the less susceptible cultivars were M-SOY 8866, M-SOY 7908 RR and BMX Potência RR and the most susceptible were BRSGO 8360 and BRS Tracajá.
