Tomato is the species grown at the highest amount within the Solanaceae family. Identification of the different gene sources that can be used in breeding studies related to tomato is important; therefore, local varieties are always found to be interesting. In this study, one plant from commercial species and 37 plants of local indeterminate genotypes picked from various regions of Turkey preserved in genbank are used. Total of 38 genotypes have been cultivated in open field of Eskişehir region during the summer season. Among 26 morphological and phonological characteristics researched in table tomatoes; fruit weight, fruit shape, skin thickness, Chroma, Hue, green shoulder in ripe fruit and lycopene level (mg/kg) are selected to be used in weighted grading method. Being featured with its characteristics, local indeterminate tomato genotypes selected by weighted grading method are identified. This study was carried out in Eskişehir, TR 68519 (Burdur), TR 72501 (Adana), TR 61921 (Denizli), TR 52128 (Erzincan), TR 40646 (Siirt) numbered “indeterminate tomato genotypes” are scored high evaluation mark. Genotypes that are potentially used in improvement studies in regard to fruit characteristics, color and lycopene levels are identified. Efficiency of weighted evaluation method and the aspects to be considered in the application are discussed.
