The study entitled “Growth, yield and quality of different processing cultivars of potato (Solanum tuberosum L.)” was carried out in the department of Vegetable Science, Punjab Agricultural University, Ludhiana during 2012-14. Different cultivars of potato namely Kufri Pukhraj, Lady Rosetta, Fritolay-1533, Atlantic, Kufri Chipsona-1, Kufri Chipsona-3, Kufri Badshah, Kufri Lauvkar, Kufri Jyoti and Kufri Chandramukhi comprised the plant material. The tubers were analysed for dry matter, starch content, total sugar and reducing sugar at the time of harvest. Present investigation revealed that Kufri Badshah had the luxuriant foliage bearing higher number of leaves, branches, number of tubers and excelled in total tuber yield. Among the various cultivars, Atlantic had maximum dry matter content followed by cultivar Lady Rosetta. The highest starch content was estimated in cultivar Kufri Chipsona-1. This cultivar was also low in total sugars and reducing sugars making it suitable for processing. Among rest of the cultivars studied the cultivars Atlantic, Lady Rosetta and Kufri Chipsona-3 were also considered cultivars for processing.
