Duku, Dokong and Langsat belong to the same species, Lansium domesticum. They are native to Malaysia, mainly cultivated in Terengganu. During the Duku season make a visit to Manir area where you can drive under the canopy of duku trees with brownish yellow duku fruits.


Duku is round in shape and slightly bigger than a golf ball. It grows in clusters with a thick leathery skin which is in golden brown colour and can be peeled into segments when gently pressed on the top of the fruit. Each fruit composed of a few segments of juicy and refreshing flesh that is tangy sour to sweet taste. Some segments may contain small and bitter seeds. The flesh is usually white but some are pink.

Duku is originated from West Malaysia but it is cultivated through out the whole region nowadays. It takes about fifteen years for a duku tree to reach maturity; but the wait is worthwhile as they bear clusters of fruit twice a year thereafter. There are farmers blend both duku and langsat and produce a new innovation species, that is the Duku-Langsat which bears the characteristic of both duku and langsat.

In Terengganu, duku is cultivated in Manir area in Kuala Terengganu. During the harvest season, there are lorries lining up outside the orchards as to collect and weight the fruits then distribute to other areas later.
