Abstract
Estimating variation in fruit mineral concentration is important for breeding mango with improvement of nutritional quality of mango. In the present study, 53 morphologically diverse mango genotypes were evaluated for phosphorus, potassium, calcium, manganese, sodium, copper, zinc, iron, boron and magnesium content on a dry weight (DW) basis in fruit pulp. Significant differences were found among evaluated mango genotypes in the mineral composition. The macro-minerals such as phosphorus, potassium, magnesium, calcium and sodium ranged from 644.66-1311.37, 6285.79-17063.11, 278.14-816.98, 146.77-640.82 and 56.94-270.29 mg kg(-1) DW, respectively. The micro-minerals such as manganese, copper, zinc, iron, boron ranged from 5.03-103.48, 3.01-8.55, 3.24-13.77, 8.13-21.71 and 0.60-10.65 mg kg(-1) DW, respectively. ‘Renong 1’, ‘Xiaoji’ and ‘Cuba 1’ had the highest Ca content and can be used as potential donors for developing calcium-rich mango cultivars. In addition, there was a positive correlation among minerals.
