An investigation of studies was carried on the fruit development pattern in accessions of jackfruit during 2014-15 and 2015-16, the accession A8 recorded a significantly higher number of female spikes (77.67 and 76.00, respectively), significantly higher values for  number of fruit set (49.00 and 47.67, respectively) were recorded in accession A1, the accession A6 took the maximum number (76.96 and 76.29, respectively) of days to fruit set, the maximum number of fruits per tree was observed in accession A1 (38.67 and A8 37.00 respectively). The high percentage of fruit set was observed in accession A1 (65.01) during 2014–15 and in accession A8 (69.51) during 2015–16. the significantly maximum days taken for  fruit maturity were recorded in accession A7 (104.60 days during 2014-15) and in accession A5 (106.50 days during 2015-16). during both the year of study the maximum percentage of fruits were produced on primary branches (60.59% and 55.78%, respectively), followed by the secondary (22.30% and 21.78%, respectively), and tertiary branches (9.55% and 9.38%, respectively). During 2014–15 and 2015–16, significantly higher values for  fruit weight (24.83 kg and 24.00 kg, respectively), fruit width (42.00 and 43.33 cm, respective years) were recorded in accessions  A7 whereas the significantly high fruit length was observed in accession A5 (54.83 and 52.67 cm, respective years). During 2014–15 and 2015–16, significantly higher values for total number of flakes per fruit (141.33 and 140.00, respectively), flake weight (46.50 g and 46.33 g, respectively), flake length (8.43 cm and 8.33 cm, respectively) and flake breadth (4.07 cm, 4.20 cm, respectively) were recorded in accessions A7. During 2014–15 and 2015–16, the accession A6 recorded a significantly maximum seed weight (7.70 g and 7.27 g in 2015–16), seed length (2.87 cm and 2.90 cm, for respective years) and seed width (1.57 cm and 1.63 cm, for respective years)
