Abstract: Background and Objective: Small eggplants called Gelatik as an alternative substitute for tomato rootstocks are local eggplants that are widely available and can be easily obtained by conventional farmers. The main objective of this study was to examine the influence of water logging durations on various growth phases of tomatoes grafted on local eggplants. Materials and Methods: The experiment was conducted between February and December 2017. The design used was Randomized Block Design (RCBD) consisting of two factors and three replications. Factor I was the grafting of Cervo variety tomatoes onto different rootstocks and Factor II was the water logging pressure at different growth phases. Results: Gelatik rootstocks (BL) treated with B2V, B2B, B2H and B4V resulted insignificant differences in leaf area, plant height and weight of fruit from that of EG 203 line rootstock. EG 203 line (BEG) resulted in significantly higher than Gelatik (BL) rootstock in terms of proline level during fruiting phase (B2H, B4H). Biplot analysis showed the positive correlation between water logging tolerance score and the content of proline. Conclusion: The local eggplant rootstocks (Gelatik) which were water logged for up to 2 days did not show any significant difference from the recommended eggplants. Therefore, the EG 203 line can be planted under a substituted condition of sandy soil and rainy season condition.
