| Summary: | Reliable estimation of mango fruit maturity has great significance in ensuring enhanced fruit quality, shelf life and market value. There is hardly any univocal criterion that can be used to correctly detect the optimum stage of fruit harvest under varied climatic conditions. Hence an experiment was conducted to optimize a reliable criterion for one of the most important commercial mango varieties of India (‘Dashehri’) under sub-tropical region. Fruits were harvested progressively in five pickings viz. 90, 95, 100, 105 and 110 days after full bloom (DAFB). Heat unit, fruit firmness, dry matter, soluble solids content and SSC/acid ratio were considered as stable attributes in defining maturation due to their low standard deviation and coefficient of variation. Harvesting of ‘Dashehri’ mango between 95-100 DAFB exhibited enhanced color development (a* and b*), fruit quality and sensory attributes with no incidence of jelly seed. On the other hand, late harvesting of fruits not only caused high incidence of jelly seed but also affected the shelf life. The findings were also evident with principal component analysis. Early harvested fruits were characterized with sub-optimal color attributes, high post-harvest weight loss and low SSC, sugar and ꞵ-carotene content. The results indicated that DAFB can be used as a reliable non-destructive index to predict optimum time of fruit harvest. Accordingly, optimal range of SSC, dry matter, firmness, heat unit accumulation and SSC/acid ratio was quantified at maturation under subtropical climatic conditions of north India.
