dc.description.abstractTomato production in Uganda is constrained by many diseases including bacterial wilt (Ralstonia solanacareum). Losses of tomato due to bacterial wilt disease have always been high because cultural practices are not effective and there have not been varieties with genetic resistance to the disease for long time. Use of resistant varieties is the only affordable, sustainable and environmentally friendly approach to manage bacterial wilt disease. This study was done to determine the level of bacterial wilt resistance of introduced tomato varieties and also establish their yield potential. Specifically, it was carried out (1) to determine the level of bacterial wilt resistance of introduced tomato varieties in Uganda, and (2) to establish the yield potential of the introduced tomato varieties. Thirteen genotypes were planted in a randomized complete block design at Makerere University Agricultural Research Institute, Kabanyolo in the second season of 2019. The treatments were replicated three times. Data were collected on bacterial wilt severity and incidence; and fruit yield. Disease severity was determined by scoring on a scale 0-5 while incidence was calculated by determining the percentage of the diseased plants. Fruit yield was determined by weighing ten fruits from each plot. Data were subjected to analysis of variance using GenStat statistical package. Analysis indicated that there were significant variations in severity and incidence among the different genotypes (P<0.001). Fruit yield also significantly (P≤0.05) varied among the genotypes. WIN ALL 802 F1 had the highest disease incidence (80.724%) and severity (3.792) while sultan F1 had the lowest disease incidence (0%) and severity (0). KOHINOOR F1 had the highest fruit yield (0.707kg). It is recommended that farmers growing tomato in bacterial wilt infested soils grow SULTAN F1 and ANJA F1 while those producing tomato in bacterial wilt free soils should grow KOHINOOR F1.en_US
