Studies on chemical composition of fruits of important mango (Mangifera indica L.) varieties in Uttarakhand

The present study was conducted to evaluate the chemical quality attributes of 43 mango varieties in tarai region of Uttarakhand. The varieties revealed significant differences for various quality parameters. The pooled data of two years study revealed that the variety Chausa exhibited maximum total soluble solids (22.11 0Brix) and T.S.S/acid ratio (152.39). The variety also revealed highest sugar: acid ratio (123.56) and non-reducing sugar content (13.36 %). However, the maximum reducing (6.12 %) and total sugar content (18.05 %) were found in cultivars Duddha Peda and Amrapali, respectively. Variety Langra Gorakhpur recorded highest ascorbic acid content (91.31 mg/100g pulp), while, the maximum carotene content (8.11 mg/100g pulp) was obtained in Amrapali. The results revealed that the varieties like Chausa and Amrapali are most superior in terms of chemical attributes. These findings can be utilized by the breeders for crop improvement programmes in future.
