Abstract: Several physical properties of three early maturated apple cultivars (Vista Bella, Summerred and Jerseymac), grown in same orchard in Northeast part of Turkey, have been investigated. The results showed that there were important statistical differences among cultivars in most of the parameters determined. Among the cultivars, cv Jerseymac (154 g) had the highest average fruit mass and followed by cv. Vista Bella (133 g) and cv. Summerred (115 g). Fruit density as kg/cm3 ranged from 929 (Jerseymac) to 946 (Summerred). The highest dynamic coefficient of friction was observed on fiberglass for all cultivars. The color intensity (chroma) was the highest in cv. Vista Bella (33.06%) while the lowest in cv. Summerred (29.39%). The projected area, surface area and sphericity of cultivars were between 36.10-39.74 cm2; 121.69-140.10 cm2 and 88.26-95.82%. These results showed that the physical properties of early maturated apples are strongly affected by genotypes.
