Hector, no need to be so condescending. Especially when your condescension is aimed at extremely successful, knowledgeable, and experienced growers, it makes you seem arrogant. I really doubt Potawie needs any "Sesame Street" lessons on growing chiles.
If a stable variety grown thousends of years,like the Bhut, takes 2-4 years to adapt to a new enviroment, a unstable hybrid or cross, should take more...
The article simply says he had poor fruit and seed set and it took him a few years to build up enough seed to run proper tests, it does not say why. You're making an assumption that it is because the bhut jolokia had to become adapted to the New Mexico climate through selective breeding (this must be what you're talking about, because natural selection/evolution takes a hell of a lot longer than 2-4 years, and that's not really at play here anyway because the plants were grown from seed each year as annuals as far as I know). You know what they say about assumptions...
Let's say that he adapted the bhut jolokia for the New Mexico climate in only 2-3 years, why is it then that so many people from all over the world are able to successfully grow the bhut jolokia from seed acquired from NMSU, and supposedly adapted to the New Mexico climate, in vastly differing climates? Including Potawie in Canada, me in Indiana, and numerous others here who live in northern climates which are a world apart from that of New Mexico? Fatalii grew very, very well for me year one, and my climate is far, far different than that of anywhere in Africa.
Let's use some examples.
A Bhut planted by Neil in Australia , Habanero500 in San Diego,Potawie in Ottawa and me in Dominican Republic...all 4 plants are going to have diferent fruit set and seed set, because each is going to adapt and stabilize diferent on diferent enviroments...diferent taste, purgency/heat , growth , everything, nothing more , nothing less, all modified by climate, nutrients and soil.
Yet so many people are able to successfully grow these plants in much different climates the first year, without needing 2 or 3 years to selectively breed that variety to grow in their climate.
We plant here scotch bonnet, we harvest year and a half without stopping each 8 days after the first harvest, after that year and a half, farmers cut the plants by the trunk and 3 months later, the same cycle for year and a half...how many growers do you know harvest each 8 days for 18 months without stopping? Does it mean we know more about scotch bonnet than jamaica? NO, just that the variety scotch bonnet in our enviroment adapted and stabilized very well.
You're talking about plants becoming adapted and stabilized in 2-4 years, the Scotch Bonnet has been growing in Jamaica for how long? I don't see any reason why they couldn't harvest from a Scotch Bonnet plant in Jamaica for 18 months straight too. There is no frost, the temperature stays a consistent 70-90 degrees year around. Jamaica is at a nearly identical latitude as the Dominican Republic and only 300 miles West. Water and wind currents obviously affect climate as well, but they seem very similar to me:
Jamaica:
* The average temperature in Jamaica is 27.1 °C (81 °F).
* The average temperature range is 2.5 °C.
* The highest monthly average high temperature is 31 °C (88 °F) in June, July, August, September, October & November.
* The lowest monthly average low temperature is 22 °C (72 °F) in January & February.
* Jamaica's climate receives an average of 811 mm (31.9 in) of rainfall per year, or 68 mm (2.7 in) per month..
* The average annual relative humidity is 74.8% and average monthly relative humidity ranges from 70% in August to 78% in October.
* Average sunlight hours in Jamaica range between 7.4 hours per day in September and 8.9 hours per day in April.
* There are an average of 3002 hours of sunlight per year with an average of 8.2 hours of sunlight per day.
Dominican Republic:
* The average temperature in the Dominican Republic is 25.8 °C (78 °F).
* The average temperature range is 3.5 °C.
* The highest monthly average high temperature is 32 °C (90 °F) in August.
* The lowest monthly average low temperature is 19 °C (66 °F) in January & February.
* The average annual relative humidity is 64.3% and average monthly relative humidity ranges from 58% in February to 66% in June to December.
* Average sunlight hours in Dominican Republic range between 5.7 hours per day in December and 7.4 hours per day in March.
* There are an average of 2316 hours of sunlight per year with an average of 6.3 hours of sunlight per day.
I don't see what the major difference is, if anything it looks like Jamaica might even have a more favorable climate. The soil is probably somewhat different, but obviously Jamaica has tons of lush vegetation, so it's not like they're growing in clay, and it's not like the soil can't be amended.
