Twenty-five jackfruit types identified through an extensive survey, during 2016 jackfruit season, were distributed in 2 districts viz., Doddaballapur (2 types), and Tumkur (16 types) districts. Analysis of variance for 33 characters in 18 type jackfruits revealed a greater variability for fruit weight, rind colour, TSS, rind thickness, bulb weight. Twenty-three of 25 fruits studied were similar in shape and were accorded standard shape number i.e. 3. Rind colour varied from, green, yellow, greenish-yellow, yellowish-green, light green, light yellow and brown. Higher fruit weight was noticed in Type-32 (11.37 kg) along with maximum fruit length (47.80 cm) and fruit breadth (27.40 cm). Rind thickness ranged from 0.70 cm (Type-49) to 1.83 cm (Type-50). Similarly, rind weight was maximum in type-32 (6.13 kg) and minimum in type-44 (1.29 kg). The type-43 showed maximum cylinder weight (0.68 kg). Total Soluble Solids (TSS) content varied from 15.50oBrix (Type-50) to 30.10oBrix (Type-47). The TSS to Acid ratio was maximum in Type-32 (244.84) followed by Type-52 (174.90). The jackfruit Type-30 (8.58), Type-50 (8.59) and Type-38 (8.23) recorded maximum score for all the sensory parameters in comparison to other types covered in the study. Above mentioned parameters are considered to select the elite jackfruit genotypes for desert type.
