A study was conducted in 50 potato genotypes were assessed based on different biochemical parameters including TSS, tuber dry matter content, specific gravity, protein content, ascorbic acid content, reducing sugars and chip colour score. The genotypes were grown at Vegetable Research Centre (VRC) of Govind Ballabh Pant University of Agriculture & Technology, Pantnagar, Udham Singh Nagar, Uttarakhand, India during 2012-13 and 2013-14. The experiment was laid out in Augumented Block Design (ABD). All of these characters showed a high level of variation among all the genotypes. The highest TSS was obtained in Laddy Rosetta (8.820 Brix°) during 2012-13 and TPSK-05-06-98 (8.280 Brix°) during 2013-14. Tuber dry matter content was recorded maximum during 2012- 13 and 2013-14 in K. Chipsona-2 i.e. 25.242 and 26.387 and specific gravity was found maximum during 2012-13 and 2013-14 in MS/95-1542 which is about 1.868 and 1.690 respectively. TPSK -05-06-44 showed highest ascorbic acid content and TPSK-05-06-117 showed maximum reducing sugars during 2012-13 and 2013-14 i.e. 2.581& 2.616 and 242.160 & 261.880 respectively. On the other hand Protein Content was found maximum in TPSK-05- 06-61 (2.581) during 2012-13 and TPSK-05-06-80 (2.616) during 2013-14. Chip Colour Score in 50 potato genotypes were varies from 2.360 to 7.360 during 2012-13 and 2.60 to 7.360 during 2013-14. The chip colour score was observed highest in TPSK-05-06-105 i.e. 7.360 and AICRP-07-05 i.e. 7.360 during 2012-13 and 2013-14 respectively.
