India is renowned for its mango diversity, with more than 1000 genotypes reported. However, the Himalayan plains bear some elite genotypes which supposed to bear high postharvest value, the systemic postharvest study of which is yet to be attempted. The aim of present study is to evaluate the postharvest quality and ripening behviour of these important genotypes. Thus, 15 un-explored mango genotypes of this region were selected and evaluated for ripening behaviour and detailed postharvest profiling via internal (total phenolic and total flavonoid content), nutritional attributes (Brix: acid ratio, total carotenoid concentration, ascorbic acid content and antioxidant activity), sensory evaluation, fruit softening enzymes (polygalactouronase, pectin methylesterase and lipoxygenase), shelf life attributes (respiration rate, physiological loss in weight and storage life in days) external attributes (fruit weight, fruit firmness, peel thickness, fruit shape and dry seed weight) and mineral contents (Calcium, potassium and phosphorous) under ambient storage (25 ± 4 °C and 65 ± 5 % RH). The results revealed that the highest total flavonoid content (682.40 μg g−1), ascorbic acid (46.88 mg 100 g−1) and antioxidant activity (4.84 μmol TE g−1) exhibited by ‘Sukul’. The total phenolic content was recorded as the highest in ‘Safed Malda’ (510.42 μg GAE g-1 FW), and total carotenoid concentration was recorded as the highest in ‘Sipiya’ (7.30 mg 100 g-1) ‘Zardalu’ (7.04 mg 100 g-1) and ‘Mithua’ (6.98 mg 100 g-1). Interestingly, genotypes such as ‘Sukul’, Sipiya’ and ‘Krishna Bhog ‘exhibited a 4–5 days higher storage life than other selected genotypes. Screened genotypes exhibited a high diversity of nutritional and biochemical contents. The results of this study bear practical utility for research (quality improvement programme) and the processing industry.
