Potato (Solanum tuberosum) cv. Atlantic and Superior were grown at alpine areas in Korea and stored at 5 and 15℃. The effects of 3-chloro-isopropyl-N-phenyl carbamate (CIPC) and cloine salt of malefic hydrazide (CMH) on the sprouting rate, reducing sugar content, and chip color of potato tubers were determined during 6 months storage. Higher sprouting ratio was observed in potatoes stored at 15℃ than those at 5℃. In particular, 1% CIPC treatment was effective in delaying and reducing sprouting. Potatoes stored at 5℃ for 180 days showed 1 % increase in reducing sugar content, resulting in dark colored chips. The chip color was found to be the best when potatoes were stored for 180 days at 15℃. Atlantic, in general, was lower in reducing sugar contents compared with Superior, producing better colored chips. As far as chip color $quot;L$quot; value was concerned, no difference was detected between two cultivars treated with sprout suppressants.
