Processing performance of Indian and exotic potato cultivars grown in Rajasthan

Nine Indian and two exotic cultivars grown at Kota (Rajasthan) were evaluated for chip colour and processing characters after harvest for 2 years. All the cultivars produced chips of acceptable colour and had a high dry matter (18.5–27.2%) and low concentrations (69–250mg/100 g. fresh weight) of reducing sugars. The chips made from Kufri Chipsona-1 and Kufri Chipsona-2 were superior in colour and taste. The amount of sucrose was much more than hexoses. Chips colour, dry matter and level of free sugars varied among cultivars and between growing seasons.
