Resumo
The 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.
