During the period between March, 2004 and January 2005, the reaction of 48 commercial cultivars of soybean to Colletotrichum truncatum was evaluated in the greenhouse facilities of the Universidade Federal de Santa Maria. The seedlings were inoculated in the stadium V1/V2 . After inoculation, plants were kept in the greenhouse under a relative humidity of 95% for 10 days, before evaluation. After that period, the seedlings were evaluated to determine the reaction of cultivars. Seedlings were evaluated for disease reaction according to a scale with values from 1 to 9. Only the cultivars Tabarana, Cometa and Emgopa 316 showed to be susceptible to Colletotrichum truncatum.
