These are the two durians people compare when they are choosing between the best of the crop, and the choice is genuinely a matter of taste rather than quality. One is rich and bittersweet, with a strong aroma. The other is creamy, lighter and less overpowering.
Both are also checked at the base of the fruit rather than the husk, but for different marks, and that is where most money goes wrong.
What each one actually is
Musang King is D197, registered as Raja Kunyit on 9 December 1993 from a tree in Tanah Merah, Kelantan. FAMA FS 092:2018 names Pahang and Johor as its main producing areas. In Malay it is Raja Kunyit, the turmeric king, and in Mandarin Mao Shan Wang.
Black Thorn is D200, one of the newer registered clones, from Kampung Lima Kongsi, Penang, and registered in 2014 according to SAYS, though other accounts give a different year. It took top honours at the 2022 World Durian Championship: Malaysia Edition (SAYS).
So one is a Kelantan clone grown mainly in Pahang and Johor, the other a Penang clone. They are not variations of each other.
Telling them apart before it is opened
Musang King: look for the star. The fruit is round to oval, with a light green or brownish grey-green husk and fairly large, medium-short, pyramid-shaped thorns. The signature is at the base: a star-like pattern where the segment seams meet, which FAMA FS 092:2018 lists as the variety’s key identifying feature.
Black Thorn: look for the single dark thorn. The fruit is almost symmetrically round, like a ball. Its thorns have dark brown tips, which give it its name, orh chi or dark thorns in Hokkien (SAYS). The decisive mark is at the base: unlike other durians it carries a single blackish-brown thorn at the centre of the base (The Star, 2015). If it has broken off there may still be a dark lump or indent.
If a seller points only at dark thorns on the husk, ask to see the base.
Flavour, and the real reason to pick one
Musang King flesh is thick, smooth and firm, in FAMA’s standard, which describes the taste as rich, sweet and slightly bitter, and the aroma as strong. The bitterness is not a defect: for people who buy Musang King, it is part of what they are paying for.
Black Thorn is creamy and lighter in texture, sweet with a slightly bitter aftertaste, and less overpowering than Musang King, according to SAYS. We have not found a source that compares how strongly the two smell.
Flesh and seeds
Musang King flesh is yellow, turmeric yellow or golden yellow, in FAMA’s standard, and comes away easily from the seed. FAMA describes the seeds as flat, with some medium-large.
SAYS, 2024 describes Black Thorn flesh as bright yellow and orangey, though the grower who raised the original tree calls it pale. We have not found a published description of its seeds.
Price, and the trap in each
SAYS, 2024 says Black Thorn can be as pricey as Musang King, if not more so, and The Star called it one of the most expensive durians as far back as 2015 (The Star, 2015), so expect premium prices for either.
The Musang King trap is the label. “Old tree”, “black gold” and King of King are seller’s terms, not grades in FAMA FS 092:2018. They are not lies, but there is no written specification behind them and two stalls need not mean the same thing.
The Black Thorn trap is ripeness, and it is easy to miss because the fruit feels right. A Black Thorn can be soft and still be unripe. It gives under a thumb much as a ripe Musang King does, while the flesh is raw-tasting and not creamy, which is the quality the variety is bought for. Sellers who eat their own stock warn about this. Judge it on the opened flesh, not softness.

Who should buy which
Buy Musang King if you want a rich, bittersweet durian, and the strong aroma is not a problem where you are eating it.
Buy Black Thorn if you want a creamy, lighter premium durian, or if you are introducing someone who finds Musang King too much.
If you are buying for a kitchen rather than a table, neither premium is worth paying: grade and variety price shape, size and appearance, and none of that survives the blender.

The 2026 season and why prices moved this year both affect what either of these should cost. The durian types register has the wider clone system.
