Abstract:
Surveys were done in major orange growing belts of Darjeeling and Sikkim hills in the fruit ripening time which was during November till February in the year 2020-2021. Mandarin collected from Darjeeling district of West Bengal (Kurseong) showed the highest fruit weight (101.87g), juice volume (56.57 ml), pulp weight (86.40 g), and seed weight (2.31 g) whereas mandarin collected from East Sikkim showed the lowest fruit weight (72.17 g), juice volume (28.78 ml), pulp weight (45.86 g) and seed weight (1.29 g). Highest total soluble solids ( TSS) of 11.69° brix was recorded in fruits collected from North Sikkim and Kalimpong. Minimum acidity of 0.65% was recorded in fruits collected from Kurseong, Darjeeling. TSS: Acid Ratio i.e. High TSS and Low Acidity which is an important qualitative characteristic for consumer acceptance and marketability was found highest in fruits collected from North Sikkim and Kurseong. Based on morphological and biochemical traits, fruits collected from Kurseong Darjeeling district were found superior for both quantitative and qualitative traits. The accession can be used for the production of quality planting material.
