You pose a very interesting question. To answer that even in part, I would have to explain that many hybrids such as Wartryx, C3P0, etc. are the result of insects so the real ancestry is not really known. When you see vendors selling hybrids with a known ancestry and an unknown hybridizer... your brain should kick in and say... How do we know the hybrid if we don't even know who created it? With that being said, hybrid is a relative term and what is taught as known is often far from it.
So many hybridizers out there that would not know a pistil if it hit them in the face.
A better question might be , How many hybridizers have you actually seen make a single documented cross? My bet is that you could count them all on one hand. Making a cross by hand... it is something many will claim but few will be able to prove.
I found this article helpful. They define superhot as 1 million scoville or higher.
The history chapter of the article seems to imply that all of todays superhots descend from the ghost pepper.
What confuses me is in the list on the wiki article, some are listed as hybrids, while others as chinense - but overall I read the article as saying that all of these varieties are really just ghost pepper descendants.
The relation between the Indian and the Trinidadian superhots is unclear… but they both have that introgression from frutescens which enables the broad capsaicinoid production. They could be independent events, or one group may be the ancestor of the other.
I should provide the minority view as well. A number of researchers insist that superhots constitute a separate species, Capsicum assamicum (see bora.pdf).
This is a matter of lumping vs splitting, so there isn’t an ultimately correct answer, but the majority of researchers, and the new monograph, do treat superhots as described by Bosland (a chinense-dominant, interspecific hybrid; see bosland.pdf).
It would make more sense to me that the Indian and Caribbean super hots developed independently rather than a Caribbean pepper making it’s way to India, being developed into a ghost type, and then making its way back to the Caribbean and being developed into a scorpion type without leaving ghost type ancestors behind in the Caribbean.
Besides that, the plants and fruit are completely different - they seem more like branches from a common ancestor rather than one coming from another.
Besides that, I am neither a geneticist nor a botanist so…..
Speaking of who made who, are scorpions just an offshoot of 7 pots? Is there any speculation on what the original super hot was?
