The physicochemical properties and characteristics of potato starches which were isolated from the six varieties were investigated. The ash content of starch prepared from the Arkula showed lower than that of the other five samples. The shapes of starch granules were oval and round, and the average diameters were in the range of $25{\sim}26.9$ microns. The main constituents of the inorganic components of each starch sample were found to be phosphorus and potassium. The amylose contents of starches were between $27.2{\sim}32%$, and blue value, alkali numbers were in the range of $0.42{\sim}0.45$ and $5.8{\sim}7.7$, respectively. Amylograph data revealed that Nook Sack had the highest viscosity at all reference points. The swelling power and solubility patterns were negligible until $50^{\circ}C$, thereafter it increased rapidly.
