Abstract: An investigation was carried out at Department of Horticulture, Junagadh Agricultural University, Junagadh during the year 2019-20. The experiment was laid out in Completely Randomized Design with Factorial concept comprising eight treatment combinations with three replications. The treatments comprised of four level of regions (R) viz., R₁ =West Gujarat Zone, R₂ = North Gujarat Zone, R₃ = Middle Gujarat Zone, R₄ = South Gujarat Zone and two level of species (S) viz., S₁ = Hylocereus undatus (White pulp) and S₂ = Hylocereus polyrhizus (Red pulp). The result revealed that among species Hylocereus undatus (S₁) recorded maximum value for physical parameters like fruit length (9.51 cm), fruit diameter (7.19 cm) and fruit weight (265.86 g). After estimation of biochemical parameters results showed that Hylocereus polyrhizus (S₂) having highest TSS (11.60 ^oBrix), total sugar (9.19 %) as well as reducing sugar (5.07 %) content. While, Hylocereus undatus (S₁) having highest non-reducing sugar (4.36 %), acidity (0.45 %) and ascorbic acid (9.95 mg/100 g) content. Whereas effect of regions as well as interaction effect found non-significant on all physical and biochemical parameters of dragon fruit.
