Robstar - I am none too sure and here is why. First off, most references state that the super hots were more of a backyard sort of thing in the Caribbean. Not a commercial sort of a thing. So there is no list. Many of the things we might be interested in are landraces, so they will be different from one community to the next, adapted locally over the years. Finally, from what I understand the vast majority of the super hots now available came from one woman with one batch of dna. They were then either refined or crossed to create what we have now.
Seems like there would have to be DNA out there that nobody in the chili head community has encountered yet. After all, there was a time when ghost peppers were the hottest peppers in the world and hot spices all come from India. Woops, we got that wrong too.
