Experiments were carried out to evaluate the reaction of three tomato cultivare to mechanical inoculation with selected isolate of cucumber mosaic virus (CMV-FvYM), in order to the further comparison with the susceptibility of the regenerants obtained from leaf explants excised from investigated plants. All tomato cultivars tested, that is: Moneymaker, Potentat and Rutgers, proved to be infected in 100%, their reaction was similar, although not homologous. The course of symptom expression and some morphological changes induced are documented. Pollen viability of infected plants was significantly lower than that of the control healthy plants.
