Book excerpt: Com a expansao da cultura da soja para novas fronteiras agricolas, varias doencas passaram a ter importancia economica. Uma delas e a septoriose ou mancha-parda, causada por Septoria glycines HEMMI, que pode reduzir o rendimento em mais de 30%. Apesar da ocorrencia da doenca, diferencas de reducao de rendimento tem sido observadas em algumas cultivares, indicando a possibilidade de selecao para tolerancia. O desenvolvimento de cultivares tolerantes, poderia aumentar em mais de cinco milhoes de toneladas anuais de soja sem despesas adicionais. O objetivo deste trabalho, foi o de fazer uma selecao de cultivares tolerantes, atraves de inoculacoes artificiais do patogeno sobre cultivares recomendadas para o Brasil. O conceito de tolerancia utilizado, foi o da cul-tivar que apesar de infectada, apresentasse pequenas diferencas de rendimento e de peso de 1000 sementes, entre plantas inoculadas e plantas protegidas com fungicida. Em casa-de-vegetacao foram testadas 139 cultivares, cada uma semeada em 2 vasos, contendo solo misturado com esterco bovino, deixando-se 5 plantas/vaso. No primeiro vaso, quando as plantas estavam entre o florescimento e o inicio da granacao, foi efetuada uma inoculacao do patogeno, com uma suspensao contendo 0,8 x 106 esporos/ml. Uma segunda inoculacao foi realizada 10 dias depois. O segundo vaso nao recebeu inoculacoes, servindo como testemunha. Quando as plantas estavam entre a granacao completa e o inicio de maturacao (estadios R6/R7.1), foi avaliado o nivel de infeccao no trifolio mais ...
