Pomegranate (Punica granatum L.) fruits can be used for fresh consumption, industrial processing, and medicinal purposes. Therefore, it is necessary to evaluate the diversity of its different genotypes to be aware of their potential. In the present study, morphological and pomological diversity of 70 native pomegranate genotypes was evaluated to introduce superior selections. Most of the characters showed significant differences among the genotypes. Fruit weight ranged from 103.28 to 407.59 g, and total aril weight per fruit ranged from 51.55 to 238.97 g. Fruit peel color was highly variable and included yellow, yellow-red, red, and red-brown. The sunburn and cracking disorders were not observed on the peel of the majority of genotypes. Aril color was highly variable, including light milky, pink, white-red, red, and red-black. Seed was soft in 17, semi-soft in 21, and hard in 32 genotypes. Total aril weight per fruit was positively and significantly correlated with fruit length (r = 0.64), fruit diameter (r = 0.87), fruit weight (r = 0.95), fruit stalk diameter (r = 0.52), fruit peel weight (r = 0.71), and aril shape (r = 0.32). Principal component analysis (PCA) showed that the fruit-related traits were important for determining differences between genotypes. Based on the ideal values of commercial characters of pomegranate, 15 genotypes were promising and thus could be directly cultivated in the orchards and used in the breeding programs.
