valuation of genotypes under greenhouse conditions comes in the first order for Tomato Breeding Program of Desert Research Center (DRC). A major objective of the program has been to develop breeding lines that possess characteristics needed in high-performing hybrid varieties at greenhouse conditions. The twelve genotypes indeterminate were transplanted in a greenhouse at Baloza Station, DRC, North Sinai, during 2016/2017 and 2017/2018 seasons. The experimental design was randomized complete block design with three replicates. The results indicated that tomato genotypes mean squares were highly significant for all traits (growth, yield and quality). Based on the results obtained in the two growing seasons, the most productive tomato genotypes and those best adapted to the climatic conditions of the area are identified. The best results of plant height, stem diameter and yield /plant were obtained from S922, S923 and S24. The genotypes S802, S811 and S812 recorded the highest mean for fruit set percentage. The genotypes S700, S710, S720 and S740 had high total soluble solids percentage. Total soluble solids percentage showed negative correlation with all characters.
