The study aimed to determine the suitable cherry tomato lines for using as a hybrid material production. Experiments were arranged in sequence without repeating. The results from estimating the General Combining Ability (GCA) of 25 tomato S4 selfing lines showed that ten S4 lines (D3.4; D10.4; D11.4; D12.4; D14.4; D15.4; D17.4; D19.4; D21.4 and D25.4) performed high GCA values based on the practical yield characteristic. Ten tomato S5 selfing lines were characterized by yielding 41.49 - 50.57 tons per ha, red ripened fruit, high brix values of 6.9 - 8.1% and medium resistance to Phytophthora infestans disease. In brief, those tomato lines could be a suitable material source for the production of F1 - hybrid tomatoes
