| Abstract | This research assessed bacterial wilt resistance in tomato germplasms infected by Ralstonia solanacearum with its yield and yield components. The study was conducted in two distinct experiments. The first experiment used a 3ร2x2 factorial experiment in a completely randomized design (CRD) to evaluate different R. solanacearum strains (factor A): To1 (biovar 4, phylotype I, sequevar 47), To3 (biovar 2T, phylotype I, sequevar 13), and Ch1 (biovar 2T, phylotype I, sequevar 17). Factor B involved two different volumes, namely 5 ml and 10 ml. Lastly. Factor C comprised of two tomato cultivars: a resistant check (Hawaii7996) and a susceptible check (VF134-1-2). The results revealed that Hawaii7996 exhibited a high resistance, with a disease index (DI) of 0%. While VF134-1-2 displayed extreme susceptibility, with DI of 100% when inoculated with To1 (biovar 4) using a volume of 10 ml. Therefore, this specific condition is recommended for accurately evaluating the bacterial wilt resistance of tomato germplasms. The second experiment was to assess bacterial wilt resistance in a total of twenty-six tomato germplasm, along with six commercial cultivars, Hawaii7996 and VF134-1-2, using a greenhouse setup. A CRD with three replications and fifteen plants per replication was used in this experiment. In addition to the bacterial wilt resistance evaluation, the yield and yield components were analyzed in open-field conditions using a randomized complete block design (RCBD) with three replications, each with ten plants. After eight days of inoculation, Hawaii7996 exhibited DI of 11.13%, while VF134-1-2 with a DI of 91.99%. Moreover, KKU-T73025, KKU-T24020, KKU-T73021, KKU-T73020, CK6, CK4, and VFT were classified as highly resistant (HR) to Moderately resistant (MR). Furthermore, KKU-T73021 and KKU-T24020 exhibited good resistance, producing 1631.08 and 2083.60 grams per plant, respectively, with yield components similar to those of CK4 and CK6. Consequently, KKU-T73021 and KKU-T24020 should be considered as valuable genetic resources for breeding programs to enhance bacterial wilt resistance during the 2-14 days after planting and maintain high productivity. |
