Diante da dispersão do vírus VMCS nas lavouras brasileiras de soja, o presente trabalho foi conduzido procurando verificar a transmissibilidade do patógeno pelas sementes portadoras do sintoma ("mancha café") característico da doença. Para tanto, material proveniente de campos contaminados foi testado quanto às porcentagens de emergência e infecção das plântulas. Os resultados obtidos permitiram concluir que o patógeno é transmitido por sementes, ainda que estas estejam livres de sintomas; contudo, apesar da inexistência de efeitos sobre a emergência, a elevação da freqüência de sementes com "mancha café" tende a ampliar o número de plântulas contaminadas. In view of the long-range dissemination of the virus SMV in Brazilian soybean fields, this research was conserned with the transmission of the pathogen by seeds that show seedcoat mottling. Seeds proceeding from contaminated fields were submitted to emergence tests and examination of infected seedlings. The results indicated that the pathogen is transmited through the seeds even when they do not show seedcoat mottling; although no particular effect was found on emergence percentage, the use of mottled seeds tends to increase the number of infected seelings
