Abstract: An experiment was conducted in main experimental station of horticulture farm situated in Acharya Narendra Deva University of Agriculture and Technology (ANDUA&T), Kumarganj, Ayodhya, India to evaluate different Citrus spp. for physico-chemical composition of fruits. Seven species of Citrus i.e T₁ (Kinnow), T₂ (Rangpur Lime), T₃ (Pant lemon), T₄ (Kagzi lime), T₅ (Nagpur Mandarin), T₆ (Sweet Orange var. mosambi) and T₇ (Grapefruit var, NRCC Grapefruit-6) were evaluated in completely randomized design with three replications. The results of the experiment revealed that the treatment T₇ (Grapefruit) showed maximum fruit weight (407.52 gm), fruit length (9.12 cm), fruit width (8.90 cm) and Ascorbic acid content (46.04 mg/100 gm). However T₁ (Kinnow) showed maximum TSS (10.61° brix) and Titrable Acidity (9.21%) and T₄ showed maximum specific gravity (1.01 g/cc). Non-reducing (5.76%) and reducing sugars (3.51%) were highest for treatment T₆ (Sweet Orange) and lowest (0.63 % and 0.75%) for treatment T₄ (kagzi lime). Whereas, for Total sugars it was observed that that T₄ was lowest (1.73%) while T₅ (8.44%) showed highest total sugars. So if physico-chemical parameters are to be concerned T₇ (grapefruit) can be regarded as the best species to be used in citrus crop improvement programs while if quality is to be concerned then Kinnow (T₁) and Sweet orange (T₆) would be the best bet for utilization in citrus crop improvement programs.
