Experiments were carried out to evaluate the reaction of cabbage cultivars to mechanical inoculation with selected isolates of the turnip mosaic virus (TuMV). Simultaneously we aimed for the assessment of TuMV pathogenicity towards cultivars chosen to be transformed in order to obtain the resistance trait. The TuMV-CAR37A and TuMV-CAR39 isolates from horseradish proved to be infective towards ‘Amager’ and ‘Langedijker’ B. oleracea subsp. capitata f. alba. The course of symptom expression was assessed and the results of virus detection in symptomless leaves, using DAS-ELISA, were documented. Both tested cultivars showed a similar level of susceptibility. TuMV-CAR37A and TuMV-CAR39 can be useful in the selection of cabbage lines with resistance to the turnip mosaic virus.
