520			_aABSTRACT Potato is a well-known tuberous plant that its storage is a necessity especially in commercial scale productions. A greater percentage of post-harvest losses in the potato value chain has been experienced and recorded during storage by many researchers, thus this research is also designed to evaluate the behavior of three potato cultivars in TRNC at different storage conditions. Giving the fact that different potato cultivars behave differently under different storage conditions, thus it is important to determine which potato cultivar as well as in which storage condition stores for longer period while maintaining its quality. Three potato cultivars (Spunta, Asterix and Alverstone Russette) were stored under 3 different temperature conditions and in different time frame. The samples were evaluated for weight loss, degree of firmness, average sprout per tuber and disease, sugar content. Data was analyzed by using SPSS at 0.5 significant level. The results showed a significant difference in firmness with respect to time, cultivar, and temperature. Firmness generally decreased with time for all cultivars in all storage conditions but the minimum mean firmness (8.381kg/cm2 ) was seen in Spunta while the highest mean firmness (9.781kg/cm2 ) was seen in Asterix The degree of firmness with respect to temperature as in the results could be represented as 40C >220C>180C. For sugar content, it increased with time for all storage conditions with significant differences seen at single, double, and triple interactions. Alverstone was seen to have the highest TSS throughout storage with a mean of 4.8750Brix followed by Asterix 4.6470 Brix and lastly Spunta 4.5470 Brix. Sugar content was seen to decrease with increasing temperature. Percentage (%) weight loss was also seen to increase with time with significant differences at all levels of interaction. Asterix posted the highest weight loss with a mean weight loss % of 17.42% followed by Alverstone (8.08%) and lastly Spunta (5.83%). The differences with respect to temperature could be represented as 180C >40C>220C. Asterix at 180C showed the highest number of average sprout (8 sprout per tuber) as compared to Spunta with 3 sprout per tuber and Alverstone with 2 sprout per tuber at the end of storage. Alverstone was seen to have the longest dormancy period. In all storage condition though with some deviations, Spunta showed a better performance followed by Asterix and lastly Alverstone when considering storing potato especially for processing purpose.
