About this variety
Gumless Jack is a selection, associated with work at ICAR-IIHR, Bengaluru, chosen specifically for its notably low latex ("gum") flow when the fruit is cut or harvested — one of the more troublesome and messy aspects of handling jackfruit generally. Its medium-sized fruit with crisp flesh is valued mainly for making harvest, cutting and processing genuinely easier and cleaner, which matters more the more a grower is selling cut or processed bulbs rather than whole fruit.
