The survey work for identifying elite jackfruit type was initiated in the year 2015 jackfruit season. During 2015 jackfruit season, 27 jackfruit types identified through an extensive survey were spread in 4 districts viz., North Canara (2 types), Chikmagalore (6 types), Tumkur (16 types) and Hassan (3 types). Analysis of variance for 30 characters in 27 type jackfruits revealed a greater variability in the survey zone. Flake thickness, bulb length and TSS exhibited a considerable amount of variation in number. Fruit weight had a range from 0.91 kg (Type-23) to 9.30 kg (Type-12). The type-12 recorded maximum fruit length (42.00 cm) and fruit breadth (30.40 cm). The bulb color varied from cream(Type-6) to Yellow(12 jackfruit types), light yellow(Eight types) and orange(four types) The maximum bulb number of 170 was noticed in the type-7. Bulb weight was maximum in Type-12 (5.42 kg) and minimum in Type-23 (0.22 kg). Bulb length showed a range from 8.53 cm (Type-17) to 3.92 cm (Type-23). Similarly bulb breadth was maximum in Type-13 (5.60 cm) and minimum in Type-5 (3.07 cm) and Type-6 (3.07 cm). Total Soluble Solids (TSS) content was noticed high in Type-18 (32.38^oBrix). The maximum score for crispness was noted Type-4 (4.90) and Type -17 (4.90). Overall acceptability score was higher in Type-10 (4.50). Type-10 (4.50) was the best and having good score for overall acceptability and other physico chemical parameters studied.
