Abstract

Bacterial canker, caused by Clavibacter michiganensis subsp. michiganensis, is a very damaging disease to tomato (Lycopersicon esculentum) farm in Korea. It infects tomato, spreads through the xylem and causes bacterial wilt and canker. Selection of resistant cultivar is the best way to prevent or reduce the occurrence of the disease. Thirty-nine tomato cultivars, twenty-one cherry tomato cultivars and thirteen rootstock tomato cultivars were inoculated with Clavibacter michiganensis subsp. michiganensis, to evaluate tomato cultivarspecific resistance against bacterial canker. In the evaluation of 73 major commercial cultivars, ``Sunmyung``, ``Sweet``, ``Akiko``, ``Dadaki``, ``Match``, ``Magnet``, ``Friend``, and ``Greenpower`` were found to have a high level of resistance to bacterial canker of tomatoes.

Key Words: Bacterial canker, Clavibacter michiganensis subsp. michiganensis, Resistant, Tomato
