While individual breeding efforts can produce useful results, the bulk of tomato breeding work is at universities and major agriculture-related corporations.

It is not a naturally occurring breed, but originates from human-controlled breeding efforts.

Both the habitat preservation effort and the captive breeding effort would have been cheaper and more likely to succeed if they had been begun earlier.
