Abstract: A survey was conducted in Nainital district of Uttarakhand for evaluation of physic-chemical characteristics in sixteen apple strains. The highest fruit weight (304.37 g), fruit volume (300.00 cc), fruit length (8.08 cm) and fruit diameter (9.05 cm) were recorded in Collection-2 whereas highest T.S.S. was recorded in Collection-5 (13.97 °B), while lowest acidity was recorded in Collection-10 (0.90%) whereas the ascorbic acid content was found maximum in Collection-16 (10.42 mg/100 g). The Collection-12 exhibited highest total sugars (10.39%), reducing sugars (9.23%) and total anti-oxidant activity (40.70 mMTE/L). Among all the strains the highest carotene content was recorded in Collection-4 (137.31 µg/100 g). The Collection-1 was the most luminous (L*=85.20), whereas the highest red colour was recorded in Collection-2 (a*=+42.26). The yellow colour (b*=+68.25) and Chroma (C*=68.89) were found highest in Collection-6, while highest hue angle was recorded in Collection-8 (h°=91.40). The most of the physico-chemical characteristics were found superior in Collection-2 and Collection-12 as compared to other apple collections.
