In order to evaluate and compare 15 different hybrid genotypes of greenhouse tomato (Solanum lycopersicum L) in Gorgan, Golestan, north of Iran, an experiment was carried out in randomized complete block design with 3 replications at two Golestan province greenhouses (greenhouse of Gorgan Agricultural and Natural Resources Research and Education Center and a private greenhouse in Gorgan). Investigated traits were fruit yield per plant, number of fruits per plant, number of fruits per cluster, average fruit weight, fruit diameter, fruit height, stem length, total soluble solids, pH, pericarp thickness, total phenolics content and flavonoids content. Statistical analyses were suggestive of significant difference in all of the studied traits between different genotypes in both greenhouse experiments. In both of the greenhouse experiments, the highest fruit yield per plant was observed in 4129, Omagna, and then Izmono, 10161, Hirad and Sakhia genotypes. Dafnis and Hiva cultivars were intermediate in terms of fruit yield compared to other genotypes. In traits such as fruit number, fruit weight, fruit size, plant height, pericarp thickness, total soluble solids, pH, phenolics content and flavonoids great differences were observed between the studied genotypes. Positive correlations of fruit yield with number of fruits per plant, mean fruit weight and fruit diameter traits were observed in both greenhouse experiments. Therefore, selecting based on the latter three attributes may improve fruit yield of tomato in seed and variety breeding programs.
