Identifying distinctive traits in sweet cherry (Prunus avium L.) cultivars is one of the essential steps to prevent the propagation of different cultivars with the same name. This research aimed to assess morphology and pomology, and identifying distinctive traits of seven commercial cultivars and five genotypes for two years according to UPOV guidelines. Based on results, nine sweet cherry cultivars/genotypes including Shisheei-Mashhad, Pishras-Mashhad, Takdaneh-Mashhad, Sefid-90, Pishras2, Shabestar-6, Dovomras-Mashhad, Siyah-Daneshkade and Siyah-Mashhad had 19 morphological and pomological distinctive traits. Takdaneh-Mashhad cultivar with a fruit weight of 10.93 and stone weight of 0.88 g was distinguished from other cultivars and genotypes. Excusive traits of thickness and length of fruit stalk made a significant difference between Siyah-Mashhad and Shabestar-6 cultivars. The number of lenticels in the one year old shoot with very high visibility differentiated the Shisheei-Mashhad cultivar from other cultivars and genotypes. In addition to fruit weight, petal arrangement and ripening time, distinguished Takdaneh-Mashhad and Siyah-Mashhad cultivars. Among the studied traits, tree habit, petal arrangement, fruit ripening and skin color, were more significant traits to distinguish the sweet cherry cultivars that most of them were in accordance with asterisked characteristics in UPOV's guidelines.
