This study was carried out in a private of cool store in Mosul-Iraq in 2011. The tubers of 27 potato cvs. Which were harvested in Spring season in Rabia- Mosul/ 2011، and stored 3.5 months (short storage) and 7 months (long storage) at 4±1 C° temperature and 90-95 % R.H. to study the storability of these cultivars. The results indicated: The Voyager variety was significantly increased in percentage of sprouting growth، percentage of weight loss and tubers decay. The Hermus variety was significantly increased in dry matter and starch percentage of tubers. While Ajiba variety was significantly increased in tuber firmnness ،and Ladyolympia variety was significantly increased in specific gravity of tubers . The long storage (7 months) was significantly increased in sprouting growth percentage. Of weight loss of tubers perc.، while the short storage (3.5 months) was significantly increased in decay tubers perc.، dry matter perc.، starch percentage. Of tubers، and tuber firmness as compared with the long storage. Interaction treatment Voyager variety in long storage was significantly increased in percentage. Of sprouting growth،
percentage. Of weight tubers، while the same variety in short storage was significantly increased the tubers decay percentage.،Hermus variety in short storage was significantly increased dry matter and starch percentage.
