Potato is an important food crop which is also valued in processing industries. Present experiment was undertaken to evaluate yield performance and storagability on 22 genotypes of potato along with quality parameters related to processing as well as cuisine purpose. The experiment was conducted in the field and laboratory of Dept. of Plant breeding, BCKV in 2011-12. In the study some of characters were measured such as dry matter, tuber shape and depth of eyes, chips color and quality, cooking type, texture firmness, flavor, starch and total sugar content. Genotypes G-4, Kufri Khyati, K. Chipsona-3 and PH-3 were found to be promising for their yield. Kufri Chipsona-3 and K-22 was found to be superior for processing purposes as these were associated with a number of desirable quality parameters like high dry matter content and starch content, low total sugar content and less blackening effect on cooked potato after cooling with persistence of good chip colour for a long period. For cuisine purposes K. Sadabahar and K. Jyoti was found to be most promising as they had tubers of good shape and shallow depth eyes, acceptable flesh colour and highly acceptable cooked potatoes. The varieties like K. Khyati, K. Pukhraj, K. Ashoka, PH-4 can be considered to increase flavor of cooked potatoes.

Globally potato (Solanum tuberosum L.) is an important food crop which saves millions of hungry people in developing countries. In India, 90 percent of potatoes are harvested in the plains in January-February at the beginning of hot summer. Seasonal production patterns, inadequate cold storage capacity, low domestic utilization, limited alternative market outlets (e.g., processing and export) often result in market gluts and poor prices at harvest resulting in economic loss to the farmers. Sometimes over production forces Indian farmers for distress sale due to lack of storage facilities or expensive cold storage. The problem may be solved by developing potato genotypes which can be stored in country storage with minimum loss. Thirty potato genotypes were evaluated for studying the keeping quality of potatoes cultivars in ambient condition to identify genotypes showing least loss during storage due to different factors like physiological as well as rottage. Genotypes V1-121, Kufri Chipsona-3 and Kufri Pushkar were found most desirable which showed minimum storage loss due to minimum reduction by combined factors causing physiological as well as rottage loss. Number of sprouts and their weight in stored tubers were found least in Kufri Sutlej and Kufri Himalini. Also Kufri Sadabahar showed maximum numbers of sprouts/tuber with minimum sprout weight and sprout length and cause low physiological loss due to sprouting.
