Today, with using grafting method, many of production problems of tomato plant, including salinity of irrigation water and soil have been overcome and a higher quality product has been produced. In this research, tomato greenhouse seedlings (transplanting) of queen cultivar grafted onto hybrid rootstocks cultivars of AR-9704, Helper and Pera with using method of cleft grafting and were cultivated with hydroponic system in greenhouse. Grafted and non- grafted (un-gragted queen) plants were compared in terms of yield and quality of fruit in salinity treatments of 0, 30 and 60 mM sodium chloride. The results showed that concentration of sodium and chlorine fruit in grafted plants in three salinity treatments was higher than non-grafted plants. In this study, highest (601 mg .100 g) and lowest (360 mg .100 g) fruit lycopene content at a salinity level of 30 mM, were related to grafting combination of queen onto AR-9704 and non-grafted-queen respectively. Highest (5090g) and lowest (4052g) fruit weight per plant at 0 mM sodium chloride were related to grafting combination of queen onto pera hybrid and nongrafted-queen respectively. Also, at the salinity level of 60 mM, highest (3200g) and lowest (1962g) yield in plant were assigned to the plants that grafted onto AR-9704 rootstock and non-grafted-queen respectively. The results showed that the AR-9704 hybrid cultivar, as compared to the two hybrid cultivars of Helper and Pera, and non-grafted-queen plants, with further supplementary studies, could be a suitable rootstock for tomato of queen cultivar under salinity conditions.
