[Synopsis] In the present study, the self-pollinated progenies of bacterial wilt-resistant line derived from tomato leaf-callus were examined for their resistance expression against infection by the pathogen Ralstonia solanacearum. The progenies (R5 to R8) of the selected line were transplanted in non-sterilized soil and cultivated for two months in a plastic house under normal conditions. These progeny plants showed the normal growth and fruit production without any wilting during the entire period of cultivation, while all of the susceptible mother tomato cultivars wilted completely. For the confirmation of the resistance of these lines, the progeny plants were transplanted to soil heavily inoculated with the pathogen. These plants grew normally in contrast to severe wilting of the control susceptible plants. These results suggest that the resistance to the bacterial wilt pathogen had been stably maintained in these selfpollinated resistant progenies of callus-derivered regenerants
