Abstract
The aim of present study was to evaluate the different pomegranate cultivars for physicochemical properties and to identify the best cultivars suitable for food processing and future breeding. Various attributes of fruit (including length, weight and diameter), rind (thickness and weight), calyx (length), aril (weight, percentage, length and width), seed (length and width) and juice (titratable acidity and soluble solids or TSS) were evaluated. Total and reducing sugar, pH, ascorbic acid, total phenolic contents, antioxidant activity and maturity index were also evaluated. A significant difference in all tested parameters was noted amongst the tested cultivars except calyx length, rind thickness, arils and seed dimensions. The antioxidant activity and total phenolic contents of pomegranate cultivars were ranged from 15.77 to 42% and 1158.9 to 1540.7 mg GAE L−1. The cultivars Tor-390 and Sorkhak-859 were sweet in taste, while the rest of the cultivars have sweet sour taste. The study concluded that the majority of cultivars were rich source of total phenolics, ascorbic acid, total soluble solid and total sugars, which are beneficial to health. Some of the elite cultivars (NKP-561, SRK-296, SZR-385, SRK-878) showed high quality attributes and were suitable for future breeding programs.
