Abstract Pistachio (Pistacia vera L.) is considered as one of the most important fruit nuts in the world. The present research was conducted on the morphological evaluation of 96 pistachio seedling trees originated from open-pollination to identify the promising genotypes. Significant differences were observed among the studied genotypes based on the measured traits. Nut dry weight ranged from 0.45 to 1.40 g, while kernel weight ranged from 0.17 to 0.80 g, and also kernel percentage varied from 27.84 to 92.17%. In addition, split nut percentage, as a very important characteristic in pistachio, ranged between 0.00 and 97.37%. Split nut percentage showed positive and significant correlations with bunch weight, fruit number per bunch, nut weight, and kernel width. Kernel weight with high standardized beta coefficients (β = 0.96, P
