Problem of fruit oblongation arises in nagpur mandarin fruits from last decades and it is dominantly increasing from last 4 to 5 years in nagpur mandarin growing regions of Akot, Amravati, Wardha, Nagpur and some part of Madhya Pradesh. The present investigation was carried out at Post Harvest Technology Laboratory, Department of Horticulture, Dr PDKV, Akola in order to study the physicochemical characteristics of physiologically disordered nagpur mandarin fruits. Samples of physiologically disordered fruits and normal fruits were collected from twenty-five orchards of five different locations (viz., Ruikhed, Anjangaon, Paratwada, Jittapur, Akot). It was found that the physiologically disordered fruits have low TSS (5.45 to 7.82 o Brix), ascorbic acid (8.43 to 14.97 mg 100 ml -1 ), reducing sugars (1.96 to 2.75%), non-reducing sugars (2.33 to 3.65%) and juice content (34.15 to 47.36%) with more acidity (0.73 to 0.80%), length breadth ratio (1.10 to 1.20), rind thickness (3.57 to 3.98 mm), pomace content (24.68 to 28.35%) and rag content (11.31 to 13.65%) as compared to normal fruits TSS (9.46 to 12.78 o Brix), ascorbic acid (32.15 to 42.57 mg 100 ml -1 ), reducing sugars (3.15 to 4.75%), non-reducing sugars (4.26 to 5.56%) juice content (49.16 to 52.24%), acidity (0.64 to 0.69%), length breadth ratio (0.85 to 0.90), rind thickness (3.57 to 3.98 mm), pomace content (24.68 to 28.35%) and rag content (11.31 to 13.65%) respectively.
