Narcissus (Daffodil) with the scientific name of Narcissus tazetta L. is a perennial bulbous plant from the Amaryllidaceae family. Narcissus is one of the most important ornamental bulbous plants that is used as a cut flower. Therefore, this project was carried out to evaluate postharvest indices of Iranian daffodil genotypes. In this research, the bulbs of narcissus native genotypes were collected from natural narcissus fields in different regions of Iran. Then, bulbs were planted in the research field, and plants were taken care of during their growth. Then, the flowering stems were transferred to the laboratory to check their storage capacity and quality in the postharvest period, and various morphological and physiological parameters such as storage period, percentage of rotten branches, percentage of wilted flowers, flower quality, and amount of chlorophyll, carotenoid, and flavonoid were evaluated. According to the results of this experiment, Mazandaran genotypes showed the highest morphological and physiological indices as storage period (8.55 days), percentage of rotten branches (10%), percentage of wilted flowers (10%), flowers quality (1 indice) and amount of chlorophyll (1.31 mggr-1), carotenoid (0.90 mggr-1) and flavonoid (1.11 mggr-1) in postharvest duration. After that, Khuzestan showed the highest values of storage period (6.77 days), percentage of rotten branches (23.33%), percentage of withered flowers (23.33%), flowers quality (2.16 index), and amount of chlorophyll (1.24 mggr-1), carotenoid (0.94 mggr-1), and flavonoid (1.05 mggr-1). Therefore, Mazandaran and Khuzestan had the highest parameters for keeping as cut flowers.
