Paper Title
Screening and Saving of Local Tomatoes (Solanum Lycopersicum) for their Resistance to Drought and Salinity

In the study, 55 tomato (Solanum lycopersicum) genotypes have been investigated for their responses against drought and salinity stresses in early plant growth stage. For these purposes, several morphological and physiological measurements and analysis have been done in both stresses and control plants. Scale classification of the visual appearance of the plants, plant height, leaf number, leaf area, relative water content, leaf water potential, leaf membrane injury index, stomatal conductance, shoot and root fresh weights, shoot and root dry weights, shoot K, Ca and Cl concentrations, root K, Ca and Cl concentrations, leaf temperature were measured and analysed. Salt and drought tolerant and sensitive (intolerant) genotypes have been found out according to the responses of the tomato genotypes to the above mentioned morphological and physiological parameters. At the end of the project, salinity and drought tolerant tomatoes that have commercial characteristics could be suggested to the growers. It is short-term outcome of the project. However, the non-commercial tolerant tomato genotypes are the potential as genetic material for improving new salinity and drought tolerant cultivars by the new breeding programs. This is long-term outcomes of the project. The seeds of the salinity and drought tolerant tomatoes are stored in appropriate climate conditions + 4oC and 5 % relative humidity in the seed storage room of the Horticultural Department of the Cukurova University for future breeding programs as genetic material.
