What it actually is
Tekka is D160 on Malaysia’s official clone register, registered in 1987. The country has been registering durian clones by D number since 1934, and the clone register has now passed 200 varieties. Tekka sits in the later batch, but it has earned its place: it is the variety most often named as Musang King’s main rival.
The confusing part is the names. The same clone is sold as Tekka, Green Bamboo, Buluh Bawah, Zhu Jiao (Bamboo Fort), and Musang Queen. That last one is a trade name and has no relation to Musang King at all, though the label clearly hopes you will think otherwise. If you see any of these names, it is the same fruit underneath.
Tekka fruit is medium to large, roughly 2 to 4 kg, oblong or oval and wider at the top, tapering toward the base. Some people describe the shape as a heart or a kidney bean.
How to spot it
At the stall, look at the husk first. It is pale green or light brown, sometimes both at once, or green with a dull brownish mesh pattern across it.
The thorns are the quickest check. They are coarse, short, and densely packed, stubbier and more closely spaced than the pyramidal spines on a Musang King, and they may curve inward near the stem. The stem itself is short, thick, and fibrous.
Flip the fruit over. Tekka often has a protruding pointed navel at the bottom, with indentations near the base. The bottom can sit surprisingly tight, and the “belly button” where the seams meet comes to a point.
Once opened, there is one marker nobody else has: a distinctive ridge or valley running through the middle of the core. The flesh is pale to golden yellow, sometimes light brown with darker patches, or a pale dusty cream. That dusty paleness is a useful tell against Musang King, whose flesh is a vivid turmeric yellow.
Seed size is genuinely disputed. Some sources say the seeds are small, others say mostly big. We say so rather than pick a side; check the fruit in front of you.
What it tastes like
The texture is thick, creamy, and very sticky, with a firm, meaty bite and less fibre than many clones. Well-ripened fruit often goes wrinkly and incredibly soft, with moist, almost liquid cream inside.
The flavour is complex and layered: an initial bitterness that melts into lingering sweetness, or sometimes the reverse, sweet first then bitter. There is a nutty, slightly savoury edge and a distinct umami note, and some fruit carries a tartness or numbing sensation that Musang King does not have. The range runs from bittersweet to very bitter. The aroma is strong and unmistakably durian, with moderate to strong floral notes, though not as pungent as Musang King.
Compared to Musang King, Tekka trades that clone’s rich yellow custard for something darker, more bitter, and arguably deeper. Devotees say its flavour has more going on. If you find Musang King too sweet or too one-note, Tekka is your fruit. If you want easy sweetness, it is not.
What to watch for
The main trap is the name game. “Musang Queen” on a signboard is not a discount Musang King; it is Tekka, and if the seller prices it near Musang King on the strength of the name, walk away. Tekka is a premium fruit on its own merits, but it is not that fruit.
The other practical point: Tekka is harder to dehusk than most varieties. Those short, dense thorns and the tight, pointed base make it awkward to open, so let the stall do it, or read how to choose durian before you try at home.
On value, remember that published figures put edible flesh at 15 to 30 per cent of whole-fruit weight, so compare packed-flesh prices, not whole-fruit prices. And with the 2026 season being a glut year, prices are running roughly half of 2025: a good time to try it.
Who it suits
Tekka is for the experienced eater, or the beginner who already knows they like bitterness. If your reference point is something mild and sweet like D13, start there instead and come to Tekka later. It pairs well eaten after a sweeter clone rather than before, so the bitterness reads as depth instead of a shock. Eat it slowly; the sticky, creamy texture fills you up faster than you expect.
