Abstract

This research investigates the nutritional composition of 10 tomato (Solanum lycopersicum L.) genotypes to identify candidates for biofortification, aiming to address global micronutrient deficiencies. The analysis reveals substantial genetic variability in nutrient content among the genotypes, which can be harnessed in targeted breeding programs for nutritional enhancement. Notably, genotypes G2 and G9 showed superior nutritional profiles, with elevated levels of essential nutrients such as protein, fiber, vitamins A and C and minerals including iron, zinc, magnesium and potassium. These genotypes also demonstrated notable antioxidant activity, particularly in lycopene and β-carotene content, which are associated with reduced risks of chronic illnesses. By examining the proximate composition, antioxidant activity and mineral profiles of each genotype, the study found considerable genetic variability in nutrient contents, which can be leveraged in targeted breeding programs aimed at nutritional enhancement. The high nutrient diversity across the genotypes provides a strong foundation for selecting parent lines in breeding, especially for mineral biofortification and antioxidant enrichment. This study supports the integration of genomic and conventional breeding strategies to develop tomato cultivars that meet the rising demand for nutrient-dense foods, thereby contributing to improved dietary quality and global health outcomes.
