Abstract Background Cherry tomato ( Solanum lycopersicum var. cerasiforme ) is valued for its high yield potential and rich antioxidant composition. This study aimed to evaluate morphological traits, yield performance, and antioxidant content of nine cherry tomato genotypes grown under field conditions in Bangladesh. The experiment was conducted using a randomized complete block design with three replications. Results Significant genotypic variation was observed for all measured traits. Fruit yield ranged from 3.78 to 5.76 kg plant −1 , with CT 44–4 producing the highest yield, followed by CT 57. Vitamin C content varied from 19.89 to 26.50 mg 100 g −1 fresh weight, with the highest level recorded in CT 51, whereas β‐carotene ranged from 0.64 to 1.07 mg 100 g −1 , with CT 46 showing the maximum concentration. Correlation analysis revealed that fruit yield was strongly associated with fruit number per plant ( r = 0.88), while vitamin C and β‐carotene showed weak association, indicating independent regulation. Principal component analysis explained 64.54% of the total variation, with yield‐ and nutrition‐related traits contributing significantly to genotype differentiation. Conclusion Among the evaluated genotypes, CT 57 exhibited a balanced combination of high yield and antioxidant content. The results suggest that CT 57, CT 46, and CT 40 are promising genetic resources for breeding programs aimed at improving both productivity and nutritional quality of cherry tomato.
