A living document. We’re building the chili family tree from the top down — starting with the newest record-breaking superhots, whose parentage is actually written down, and working backward toward the old landraces and wild species, where the trail goes cold.
Why this isn’t really a "tree"
It’s tempting to picture pepper ancestry as a neat tree where every variety has one parent above it. Below the species level, that picture breaks. Most chili history is a network, not a tree: varieties are crossed, back-crossed, and re-crossed, and traditional types cross-pollinate freely in the field. So a single "tree" can’t honestly represent it.
Our approach is to record relationships, not just positions on a chart, and to tag every relationship with how solid the evidence is. That distinction matters: a modern bred superhot may have a documented, intentional cross on record, while a centuries-old landrace has no recorded parentage at all — only a region and a genus.
Confidence tags we use
- Documented cross — an intentional, recorded breeding cross (named parents, often a breeder and a code name).
- Breeder claim — a stated parentage from the breeder that isn’t independently verified, sometimes disputed.
- Natural introgression — gene flow between species confirmed or suggested by DNA markers, not a deliberate cross.
- Landrace / unresolved — a traditional regional type with no documented parents.
The modern superhots (parentage on record)
Pepper X
The current Guinness World Record holder for the world’s hottest pepper, certified in 2023. Like the Carolina Reaper, it was developed by Ed Currie of the PuckerButt Pepper Company. Its exact parentage has been kept largely proprietary, so for our purposes it sits as Documented cross — parents undisclosed.
Carolina Reaper (HP22B)
Held the world-record title from 2013 until Pepper X surpassed it in 2023. Developed by Ed Currie over roughly a decade of selection. The code name HP22B comes straight from his breeding notes ("Higher Power, pot 22, plant B") — a useful reminder that this lineage exists precisely because someone documented it.
- Parentage (Documented cross): a particularly fierce habanero from the La Soufrière volcano region of Saint Vincent, crossed with a Naga-type / ghost pepper from Assam.
- Species: Capsicum chinense
This single entry already reaches back toward two of our deeper nodes: the habanero branch of C. chinense, and the Naga / ghost branch of South Asian superhots.
The building blocks they descend from
Ghost Pepper (Bhut Jolokia / Naga Jolokia)
The 2007 world-record holder and a parent (directly or through Naga relatives) of much of the modern superhot wave.
- Parentage (Natural introgression): morphologically and genetically a Capsicum chinense cultivar, but DNA marker analysis (RAPD) indicates some genetic material introgressed from Capsicum frutescens. It is, in effect, a natural interspecific blend rather than a deliberate cross — and it’s closely related to the Naga Morich of the same region.
- Species: C. chinense (with C. frutescens introgression)
This is one of the most important nodes on the chart: it’s where a superhot lineage crosses a species boundary, which a strict tree can’t show.
Naga Morich
A traditional superhot of Bangladesh and Northeast India, closely tied to the ghost pepper complex and a frequent parent or sibling in Naga-type crosses.
- Parentage (Landrace / unresolved): regional landrace, no documented parents.
- Species: C. chinense
Trinidad Moruga Scorpion & the 7 Pot family
Caribbean superhots from Trinidad — Trinidad Moruga Scorpion, 7 Pot Douglah, 7 Pot Brain Strain, and relatives. These are the Caribbean counterweight to the South Asian Naga group, and many appear repeatedly in superhot crosses.
- Parentage (Landrace / unresolved): Trinidadian landraces, no documented parents.
- Species: C. chinense
Naga Viper
A useful cautionary node. Its widely repeated parentage is a three-way cross of Naga Morich, Bhut Jolokia, and a Trinidad Scorpion — but this comes from the breeder and the variety is reportedly unstable across generations.
- Parentage (Breeder claim): Naga Morich × Bhut Jolokia × Trinidad Scorpion (unverified, unstable).
- Species: C. chinense
Where the trail goes (and where it goes cold)
Follow the modern superhots back and the branches converge on a handful of older nodes: the habanero group of the Caribbean and Central America, the Naga / ghost group of Northeast India and Bangladesh, and the Scorpion / 7 Pot group of Trinidad. Almost all of these are Capsicum chinense — with the notable exception of the ghost pepper’s C. frutescens contribution.
Past that point, documented parentage largely disappears. Habanero and Scotch bonnet, for instance, are best understood as sibling cultivar-groups within C. chinense that developed separately through long cultivation — not as a parent-and-child pair. From there the only reliable links are at the species and geographic-population level, which is where the published genomic science takes over.
Next entries to add
- Trinidad Scorpion "Butch T", Dragon’s Breath, Komodo Dragon, Infinity Chili, 7 Pot Primo
- The habanero sub-branch (Red Savina, orange/chocolate/white habaneros, Scotch bonnet group)
- The species-level backbone (the five domesticated Capsicum species) as the root the whole network hangs from
Sources consulted include published horticultural research on Bhut Jolokia’s species identity (HortScience), Capsicum domestication and genomics literature, and breeder statements for the modern cultivars. Parentage confidence is flagged per entry; "breeder claim" and "undisclosed" items should not be treated as verified fact.
