RESUMO

This work was developed to adapt culture filtrates of Alternaria solani to be used in vitro selection of resistant potato. Three isolates of A. solani (I1 and I2) from Eldorado do Sul and Rio Pardo were used. Two liquid media, V8 and Czapek, were used to grow each of the fungal isolate, giving six culture filtrates (I1V8, I2V8, I3V8, I1Cz, I2Cz and I3Cz). Two sterilization forms, Millipore and autoclave were tested. There was no difference in these two sterilization forms. Tissue culture and toxic filtrates of A. solani have a potential to reduce the time in selection of resistant potato.
