Abstract
Tomato, the most important vegetable crop in Uganda, is produced mainly in peri-urban areas for fresh-market consumption. One of the major disease constraints on tomatoes is Bacterial wilt (Ralstonia solanacearum), a soil-borne disease for which there are no control options available in Uganda. To identify and test alternative control options for this disease, the IPM CRSP tomato program carried out an on-station trial to test 13 new tomato Hnes versus four currently available ones for resistance to bacterial wilt. In 200la the introductions from AVRDC Taiwan have shown high resistance to Bacterial wilt for one season, though most of them are susceptible to Late BHght. In the two seasons, the older varieties were slightly more susceptible.
