Assessment of combining ability in tomato genotypes (Solanum lycopersicum L.) for quality traits

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.
