You spot a D10 by its green cap, and you lose one to its habit of splitting before you are ready. A ripe fruit cracked open on the branch in my greenhouse last season, weeks of care undone by a husk that could not hold itself together. That fragility is a big part of why this old clone has quietly slipped off most growers’ lists.
I grow durian under glass in San Diego, and I keep a couple of D10 trees more for their history and their flesh than for any hope of a reliable crop. On our Exotic Fruits and Vegetables table it draws questions purely on looks, since a green-husked durian stops people who assumed the fruit only came in brown. Behind that green skin sits a variety worth knowing, even as it fades from the orchards.
What D10 Green Head actually is
D10 is a registered Malaysian clone, called Green Head for its bright husk, and also known as Durian Hijau or Super 10. Its green skin is the headline feature, wrapped in small, short thorns that sometimes carry brown tips. The flesh underneath is thick and bright yellow, and the seeds tend to run small and flat, which leaves a generous amount to eat.
The green durians are a confusing family. D10 Green Head is the registered one, but it gets muddled with Kacang Hijau, D145 Tuan Mek Hijau and D165 Green Skin, all of which wear some version of a pale or green coat. Color alone will not tell them apart.
This clone matters beyond its own fruit. It is a parent of MDUR88 (D190), one of MARDI’s bred hybrids, so even as the original clone grows scarce, its genetics carry forward in newer, hardier varieties. Here is how I pick a true D10 out of the green crowd:
- Husk: bright yellowish-green, the green-head tell.
- Thorns: small and short, sometimes brown-tipped.
- Shape: round to oval, usually 1 to 1.7 kg.
- Flesh: thick and bright yellow, with a nutty sweetness.
- Seed: often small and flat, leaving plenty of flesh.
The surest confirmation is to open one: a true D10 pairs the green husk with thick yellow flesh over small flat seeds. Husk color on its own fools people constantly, given how many green durians share the stall.
Growing a fading heritage clone
Green Head wants the same tropical warmth as any durian, so my greenhouse holds nights above 22 C, and every tree is a grafted selection on kampung rootstock. The trouble is that this clone brings a stack of weaknesses modern varieties were bred to fix. It splits easily and keeps poorly, and it is sensitive to Phytophthora, the root and stem rot that ends durian trees.
| Requirement | Target for D10 |
|---|---|
| Daytime temperature | 24 to 32 C (75 to 90 F) |
| Night minimum | Above 22 C; growth stalls below it |
| Soil pH and drainage | 5.5 to 6.5, sharply drained to fight root rot |
| Water | Around 2 inches weekly; shallow roots |
| Keeping quality | Poor; the fruit splits and sours fast |
| Spacing (field) | 9 to 12 m between grafted trees |
Because it takes Phytophthora badly, D10 punishes any lapse in drainage. Mine sits on a raised bed cut heavily with pumice, and I still watch the trunk base for the dark, weeping lesions that signal the rot has taken hold. Is your soil sharp enough to keep root rot off a tree that has no natural defense against it?
On paper, D10 is a poor commercial bet. It splits on the tree, spoils within a day, and catches disease easily, which is exactly why it has drifted into rare-cultivar status and is no longer recommended for new plantings.
None of that erases what the tree does well, which is set thick, high-quality flesh on small seeds. My honest read is that D10 survives now as a collector’s tree and a breeding parent rather than a crop. Are you putting one in the ground to sell fruit, or to keep a piece of durian lineage alive?
Deciding whether an old clone is worth the years it takes to fruit depends on knowing its growth curve. The calculator below maps a durian’s growth and maturity timeline from planting, so you can see how long a slow heritage tree like D10 will take to earn its space before you commit to it.

Taste and buying it well
The eating is where D10 defends itself. The aril is thick and bright yellow, with a sweet, nutty flavor and only a subtle bitter note, and its quality is rated very good by the people who still seek it out. Small flat seeds mean a big bite is mostly flesh rather than stone.
For flavor and flesh yield, D10 holds its own against clones that have long since overtaken it commercially. The nutty sweetness and the small seed are the reasons anyone bothers keeping the variety around at all.
That same fragility follows the fruit off the tree. This fruit does not wait for you, so the window between ripe and ruined is short, and a D10 that has sat a day is rarely worth eating. Can you get one from tree to table the same day, or are you buying a fruit already on its way out?
Check the husk for cracks before you buy, since D10 splits so readily that a fissured fruit is usually past its peak. A clean, intact green husk is the first sign you have caught one in time.
Given its rarity, D10 turns up mostly at older Malaysian stalls rather than in the mainstream premium lineup. To buy one well, I work through a quick check:
- Buy it the day you plan to eat it, since it sours faster than modern clones.
- Inspect the husk for splits, and pass on any fruit that has already cracked.
- Confirm the small flat seeds, not just the green skin, to rule out look-alikes.
- Eat it fresh on the spot, because storage is not this variety’s strength.
- Judge it on the flesh, which is the only reason to chase a fruit this delicate.
| Trait | D10 Green Head | MDUR88 (D190) |
|---|---|---|
| Husk | Bright yellowish-green | Standard green-brown |
| Flesh | Thick, nutty-sweet | Thick, custard-like |
| Seed | Small and flat | Small to medium |
| Keeping quality | Poor, splits easily | Holds well after falling |
| Status | Rare, not recommended | Bred partly from D10 |
Since D10 spoils so fast, knowing roughly how long a given fruit will hold is genuinely useful before you buy more than you can eat. The tool below predicts storage life and the safe eating window from the fruit’s ripeness and conditions, which matters more for a splitter like this than for a sturdy export clone.

Is D10 worth it
As an eating durian, D10 rewards anyone lucky enough to find a fresh one. The thick, nutty flesh and small seed give real eating value, provided you accept that you must eat it the day it drops and never count on storing it.
Grown as a tree, it is a labor of love rather than a sound investment. The splitting, the short shelf life and the disease sensitivity all argue against planting it for profit, so reserve it for collectors and breeders who value its flesh and its bloodline. My San Diego D10 will keep cracking open ahead of schedule, and I will keep growing it anyway, because a green-husked durian with flesh this good is worth a little heartbreak.
