Let's see, Butch Ts, No, seeds of the unstable hybrid were sold by the Hippie Seed people (name of their business) all over the world right after that got the record. The resulting pod shapes varied a lot, but they are all Butch T peppers. Those people who got some sort of genetic material, probably kept the plants that looked the best for the next year. Butch himself has improved on his own namesake and got the form more stabilized. Yes, the true form might have been one plant, but they had many plants to start with and the samples of pepper material that they sent out for testing came from different plants as well. When they do a scoville test, it can be some blended up material and pod shape is not relevant.
I don't know the facts on the bhut flowers, but they just don't seem to want to set as much on their own, buy when pollen from different flowers gets on them, they set real well. When I have particular plants isolated for seed production, all the plants are getting a mixture of pollen from whatever flowers I did before them. In the greenhouse where I have most all of my plants, I'm just going down each row and painting every open flower, no matter what type it is. Seeds from my pepper production area could be all kinds of mixed up hybrids. Also, I would not assume this is gospel, but I think one grain of pollen will set one pepper. There may be 1000 grains on a flower, but only one does the actual fertilizing.
At Bed Bath and Beyond, they had a three piece set of little plastic bottles that look just like miniature old fashioned ketchup bottles. They are about 2 inches tall and have a snap on top. They were a set of three and they are different colors.
I take one of these when I go to certain restaurants. Blue is 7 pod Primo powder, the red is smoked bhut powder when I go to a BBQ place, and the light green is yellow brain strain powder, which yellows are good for chicken and fish dishes, where red ( primo in this case, but regular but powders are good too) powders usually taste better with pork and beef dishes. Just in case, I will still put a single bottle into a snack sized baggie while transporting.
