Combining ability effects (GCA and SCA) were estimated using seventeen parents including fourteen females and three males of tomato (Solanum lycopersicum L.) and their hybrids developed through line × tester method. The results indicated that the lines, HUB46 for fruit firmness and number of locules, HUB36 for fruit pH (-ve direction) and shelf life, HUB3 for equatorial diameter and TSS, HUB45 for pericarp thickness and polar diameter whereas, among testers Arka Vikas for fruit firmness, pericarp thickness, fruit pH (+ve direction), polar diameter exhibited significant gca effects and considered as good general combiners. Cross combinations HUB3×DMT-2 for fruit firmness and pericarp thickness, HUB10×DMT-2 for number of locules, HUB47× Arka Vikas for fruit pH (+ve direction), HUB14× Arka Vikas for TSS, shelf life and polar diameter, HUB4×PKM-1 for equatorial diameter exhibited significant positive sca effects and regarded as good specific combiners.
