The tomato, an essential food for humans, is frequently referred to as "protective food" since it contains abundant quantities of vitamins, minerals, phenolic compounds and organic acids. Prevalence of tomato leaf curl virus is a major hindrance for successful production of tomatoes in tropical and subtropical parts of the world. Besides, tomato fruit is highly perishable and vulnerable to significant post-harvest losses. So, genetic improvement for resistance to tomato leaf curl virus, enhancement of shelf life, fruit quality, and productivity helps in sustainable production of this important vegetable crop. The present study aimed at determining combining ability effects of parents and gene action for conditioning 8 quantitative traits through line × tester analysis. Three ripening delaying mutants having longer shelf life of fruits were employed as lines and 7 leaf curl virus resistant genotypes possessing specific tomato leaf curl virus resistant gene (s) (
