In the study there were two sets of experiments consisting of sixteen potato varieties eg. Baraka, Cardinal, Kronia, Mirka, Multa, Patrones, Alpha, Desiree, Extima, Jaerla, Marijke , Nicola, Resy, Sinaeda and Ukama in the first set and thirty varieties eg. Cardinal, Kronia, Micka, Multa, Patrones, Alpha, Estima, Nicola, Resy, Sinaeda, Ukarna, Vulkano, Aderna, Colmo, Diamant, Elvira, Gracia, Lutina, Marijke, Olinda, Ref'Iecta, Troubadour, Cleopatra, Altena, Ropta A-83, Osris, Fanfare, V D W 70-26 and ZPC73-G117 of Holland origin and Kufri Sindhuri of Indian origin. The former set was planted on October,1979 using second generation that is once multiplied seed potatoes and the latter on December 13, 1979 using first generation that is freshly imported seed potatoes. In each set of experiments all the varieties were replicated thrice. Intercultural operations including irrigation were done as and when necessary. Bane ting of potatoes was done as soon as 80-90% of leaves dried up due to maturity. Immediately after harvesting 5 kg of potatoes from each replication were weighed on air as well as under water in order to determine the Under Water weight (UWW) which is reported to be one of the major criteria for internal tuber quality. Five kilogram of potatoes from each variety were then taken and peel during potatoes peeler, sliced into I. 5- 2 mm in size by a vegetable slicer the sliced potatoes were washed for about 2 min in running water in order detach the free starch, and then they were fried in a thermostatically con trofrier at a constant temperature of 175°C using peanut oil till the bubbling stopped. The chip colour was rated by the help of colour card m 'Colour Card for Quality Evaluation of Chips, developed by the Institute for rage and Processing of Agricultural Produce, Wageningen. The Netherlands, the request of European Association for Potato Research In this 'Colour Card' the figure 1 means very dark and 9 means very light coloured chips. The chips are rated 5 to 8, are acceptable to the consumers.
