An investigation was undertaken during the year 2024 at College of Horticulture, Mudigere to study the physico-chemical properties among seven commercial jackfruit cultivars of Karnataka. The physico-chemical properties of the selected jackfruit cultivars were significantly different. The characteristics studied were viz., dry matter, texture, colour, TSS, protein, crude fiber, carbohydrates, calcium, potassium, total sugars, reducing sugars, non-reducing sugars and total carotenoids. The physical characteristics of fruit such as the highest dry matter (30.96 %), flake texture (43.35 N), TSS (28.47ºBrix), colour value L* (65.10) and a* (29.73) was observed in Shankara cultivar whereas, the color value b* (52.73) was higher in case of cultivar Prakashchandra. With respect to bio-chemical parameters of the fruit, the maximum reducing sugars (9.63 %), non-reducing sugars (15.51 %), total sugars (25.14 %) and carotenoids (567.80 μg/100g) was obtained in cultivar Shankara while, Siddu cultivar recorded the maximum calcium content (46.08 mg/100g) and Tamaka selection-2 obtained the maximum potassium content (401.64 mg/100g). Among proximates, cultivar Vietnam super early recorded the maximum protein (2.59 %) and crude fiber (3.90 %) content while, the carbohydrate content was maximum (24.50 %) in Tamaka selection-2

Cultivars, TSS, calcium, potassium, total sugars

From the present investigation, it can be concluded that the commercial jackfruit cultivars selected under different regions of Karnataka exhibit wide variations in terms of physio-chemical characters. The variations in these characters of the jackfruit cultivars can be utilized in crop improvement programme of jackfruit in future as well as for processing
