Evaluation of selected jackfruit (Artocarpus heterophyllus L.) accessions for quality attributes

A. Aswini, K. Lila Mathew
A study on evaluation of selected accessions/cultivars of jackfruit (Artocarpus heterophyllus L.) accessions was carried out at the College of Horticulture, Vellanikkara, Kerala, India, during August 2013 to June 2015. Variation was observed with respect to fruiting season, fruit clustering habit, fruit number (21 to 135), shape, surface, fruit weight (1.65 to 20.00 kg), fruit yield (41.25 to 1593 kg plant‑1), latex exudation, rind colour and thickness, core length (10.20 to 50.50 cm) and thickness (2.50 to 13.90 cm), number of flakes (bulbs) kg‑1 of the fruit (12.61 to 71.15), weight of flake (16.69 to 33.91 g), flesh thickness (1.26 to 7.8 mm), bulb diameter (6.08 to 10.11 cm), shape, pulp flavour, colour and consistency, number of seeds (44 to 482), 100-seed weight (240 to 800 g) and rind, flake and seed ratio (2.30 to 7.31). Variations were also observed in biochemical characters viz., TSS (20.30 to 33.80 °Brix), reducing sugars (6.61 to 13.16%) and non-reducing sugars (5.16 to 13.29%) and β-carotene (0.99 to 12.94 mg 100 g‑1). Based on yield and quality attributes of the fruits, the accessions 1, 3, 5, 7, 10, 14 and 15 were found promising.
