Conteúdo: | A greenhouse experiment was conducted during 2001-02 to evaluate the reaction to stem canker of F8 soyabean lines and analyse the consistence of the symptom evaluation in different periods, as well as the consistence of scores based on different numbers of plants per row. Twelve days after sowing, the plants were inoculated with isolate CH 08 of Diaporthe phaseolorum var. meridionalis by the tooth-toothpick technique and the symptoms evaluated 10, 20, 40, and 73 days after the inoculation (DAI). Ten lines with resistance reaction were identified. The scores attributed in the different evaluation periods were in line and the evaluations realized 10 and 20 DAI were sufficient for an identification of lines with resistance reaction. Five plants per treatment are sufficient for an evaluation of the reaction in endogamic lines.
