Determination the physical properties of the grain is important for designing harvest equipment, transportation and processing. The aim of this study was to investigate different wheat genotypes in terms of physical properties of seeds in a completely randomized design with three replications. Treatments were 24 genotypes (18 line and 6 cultivar). The physical characteristics such as the length, width, thickness, geometric mean diameter, arithmetic mean diameter, sphericity, surface area, volume, particle density, bulk density, grain weight and porosity were determined using standard methods. The cluster analysis of physical and gravity properties of seeds, grouped 24 genotypes in four categories. Genotypes 12, 16, 17, 18, 19, 20, 21, 22 and Darya cultivar in terms of the mentioned traits showed better results than other genotypes and could be introduced as the best genotypes. These genotypes had the maximum length, width, thickness, geometric mean diameter, arithmetic mean diameter, grain weight, volume, particle density and bulk density.
