Cornelian cherry ( Cornus mas L.) is known as a medicinal plant. It can be used as a fresh or dried fruit. In this study, color characteristics and some physical properties of three Iranian genotypes of cornelian cherry were studied. Color characteristics, true density and static coefficient of friction of cherries were measured using the L*a*b* model, toluene displacement method and tilting table, respectively. Dimensions, equivalent diameter and sphericity were also measured. Lightness, redness and color density of three genotypes were in the range of 20.68 to 26.10, 16.88 to 24.72 and 17.90 to 26.01, respectively. The maximum amount of bulk and true density were obtained for the genotype C2 (861 and 1118 kg/m 3 ) and the maximum amount of repose angle was obtained for the genotype C12 (75 ° ). Genotype C13 had the maximum value of porosity, sphericity and static coefficient of friction on the steel surface (23.54, 86.17 and 1.22 %, respectively).PRACTICAL APPLICATIONS The marketing of agricultural products such as cornelian cherry and their by‐product depends on the quality of primary products and the type of process operation at postharvest stage. The efficient process operation of cornelian cherry such as handling, cleaning and sizing depends on appropriate performance of the equipments used. The designing of suitable equipments needs knowledge about physical properties of cornelian cherry. In this study, the physical properties of cornelian cherry were measured. The results of present study could be used to (1) identify optimal configuration of cornelian cherry process equipments; (2) design and construct the cornelian cherry process equipment; and (3) sort and select cornelian cherry genotypes based on their quality.
