As a result of human-induced effects, the world ecosystem is changing negatively from day to day and the future of food production is under some threats. Particularly, Mediterranean Region like moderately humid mid-latitude climate regions are faced with risks such as drought and high temperature as a result of climate change and the changes in precipitation amount and regime caused by it. Although tomato is a relatively new species in the Mediterranean Region, it is one of the most commonly used vegetables in culinary culture. Turkey is a country in this region that produces and consumes tomatoes in every sense and has great genetic diversity due to its different climatic characteristics and cultural differences. Due to the aforementioned negative effects, it is gaining importance day by day to reveal the qualities of the existing genetic resources and to identify the breeding starting materials that can be hopeful against these stress conditions within the framework of the sustainability of tomato production. For this purpose, in this study, genotypes obtained from different regions of Turkey, which were selected after screening at an earlier stage against drought, were tested under deficit irrigation conditions in the greenhouse and the characteristics of the genotypes were tried to be revealed.
