What it actually is
The most useful thing to know about D101 is that much of the fruit bought under that name in Malaysia is, by many accounts, D168, registered in 1989 and best known as Mas Muar. Specialty Produce lists its other names as Hajah Hasmah, Muar Gold, Johor Mas and Durian IOI. One explanation offered for the mix-up is that IOI is easily misread as 101.
The true D101 is a different and lesser-known variety: Bangkok Tree 16. It was registered in 1970 from the Department of Agriculture’s collection at Serdang, Selangor, and DurianPro describes it as a Thai-origin seedling. True D101 is uncommon, and most stalls that say D101 mean D168.
Malaysia’s clone register uses D numbers, which now run past D200. That makes the D101 versus D168 confusion more than a nickname issue. They are separate registered clones. See the durian clone register for the wider system.
How to spot it
At a stall, you are usually identifying D168 sold as D101, rather than true D101. Specialty Produce describes the fruit sold as 101 as medium to large, averaging 2 to 3 kilograms, and oblong to round.
The same entry describes a dark green husk covered in long, conical, sharp spines with brown tips, and a small star-like pattern at the base. Handle it with care.
Once opened, the flesh is golden yellow, sometimes mixed with shades of orange, in the same description.
Do not use flesh colour alone as proof of the variety. The market name D101 is already unreliable.
What it tastes like
Specialty Produce describes Mas Muar, the D168 commonly sold as D101, as having “a candy-like, honeyed sweetness followed by a slightly bitter, lingering aftertaste”. Its entry for durian sold as 101 gives a subtle aroma, sweet vanilla-like flavours and “subtly bitter, sometimes sour nuances” (Specialty Produce).
Specialty Produce’s 101 entry describes the flesh as smooth, creamy and custard-like, soft and paste-like without being watery. Its Mas Muar entry describes it as creamy but slightly fibrous, firm and dry, so expect it to vary.
Compared with Musang King, which the Department of Agriculture describes as bitter rather than slightly bitter, the fruit sold as D101 is described as the sweeter eat. If you prefer sweetness and soft flesh, it is an easy place to start.
What to watch for
The main trap is the name itself. A seller may honestly call the fruit D101 because that is the local market label, while the fruit is actually D168 Mas Muar. Ask whether they mean true D101, Bangkok Tree 16, or D168. If they cannot say, treat “D101” as a flavour and market category rather than a confirmed clone identity.
A second, pricier trap: DurianPro lists Wang Zhong Wang, King of King, among D168’s market names, written 王中王 and romanised wang zhong wang, a label Musang King sellers also use and that no standard defines. If you paid Musang King prices for something called King of King, and it tastes this mild and sweet, ask which fruit you actually bought.
Do not assume that a bright orange or reddish-looking flesh proves it is Red Prawn. D168 sold as D101 can also show golden yellow flesh shading to orange. The same caution applies to price. Compare whole-fruit prices with whole-fruit prices, not with packed flesh prices. One recent review puts edible flesh at 15 to 30 per cent of whole-fruit weight. The guide to choosing durian is useful before you commit to a large fruit.
Season affects availability and price. Malaysia’s main season usually runs from June to August and often into September, with July and August as the peak. For current conditions, see the 2026 durian season update.
Who it suits
This suits beginners who want sweetness first. The bitterness that sources describe is slight and comes as an aftertaste.
Eat it after Musang King if you want a sweeter finish. It also works well beside Red Prawn as a comparison.
