A SUMMARY OF THE GENETIC RESOURCES OF JACKFRUIT (ARTOCARPUS HETEROPHYLLUS LANK.) IN WEST BENGAL, INDIA

The collection and evaluation of over 1460 jackfruit trees in West Bengal was initiated in 1990. Thirty-five types have been identified as superior clones and are being conserved at the Faculty of Horticulture Research Station. Wide variability in yield (15-1450 fruits/tree), fruit weight (1.22-17.30kg), fruit shape, peel colour, flake colour, number of flakes (30-380/fruit), number of seeds (30-365/fruit), texture of flakes, flake weight, total soluble solids (9.1-28.0%), total sugar (7.6-23.6%) and fruit acidity (0.10-0.33%) were observed among the genotypes. The growth, bearing (twice a year in some types) and maturity (June-September) of fruits also showed variations among the genotypes.
