Tomato grafting can be considered an important strategy, especially in organic production. This work aimed to evaluate the performance of plant biometric indicators, fruit production quality, and quality indicators of five local tomato varieties Ștefăneşti 30, Ştefăneşti 67, Siriana F1, Costate 23, Ştefăneşti 24 grafted on the rootstock of Solanum sisymbriifolium sp., cultivated in an ecological system in a protected space. The rootstock used in this study increased both the weight of the roots and their number and improved the quality indicators in all the varieties analyzed. The rootstock induced a production increase of 1.4 kg/plant in the Ștefănești 22 variety, 1.25 kg/plant in the Costate 23 variety and 2.07 in the Ştefăneşti 30 variety. The use as rootstock of sp. Solanum sisymbriifolium proved to be a good choice to achieve good performance in organic culture. Future, it is recommended to continue additional studies for several years regarding the evaluation of the influence of the rootstock and on the tolerance of the varieties to the attack of the main pests.
