VARIETIES SUITABLE FOR PROCESSING

Indian potato varieties were majorly developed for consumption as fresh potatoes until late 90's. Among these, only few varieties have desirable morphological characters, high dry matter and acceptable reducing sugar level for processing purposes, which include Kufri Jyoti, Kufri Chandramukhi and Kufri Lauvkar. With the emphasis on developing processing varieties, the varieties viz. Kufri Chipsona-1, Kufri Chipsona-2, Kufri Chipsona-3, Kufri Chipsona-4, Kufri Frysona and Kufri Himsona have been developed and few more are in pipeline. All these processing varieties released by CPRI meet the morphological and biochemical requirement for processing. Due to the cultivation of processing potato varieties on large areas in India, the availability of raw material for processing is no longer a constraint. Tuber characters and processing quality of these varieties are shown in Table-1.
