| Abstract |
|
Bacterial wilts, caused by Ralstonia solanacearum, is a very destructive disease to tomato plants (Solanum lycopersicum) in Korea. Selection of resistant cultivar is the best way to prevent or reduce the occurrence of this disease. Thirty-nine tomato cultivars, twenty-one cherry tomato cultivars and thirteen rootstock tomato cultivars were inoculated with Ralstonia solanacearum, to evaluate tomato cultivars for resistance against bacterial wilts. Thirty-seven cultivars were highly susceptible to bacterial wilts and 61-100% of their whole tissue became wilted within 10 days after inoculation. Twenty-four cultivars showed moderate resistance and twelve were resistant to bacterial wilts. In an evaluation of 73 major commercial cultivars, ``Lilyance``, ``TP-7``, ``Choice``, ``Dadaki``, ``Akiko``, ``Redstar``, ``Match``, ``B-blocking``, ``Magnet``, ``Support``, ``Friend`` and ``Special`` were found to have a high level of resistance to bacterial wilts of tomatoes. |
