The standard method for producing tetraploid plants has been the use of
colchicine, which is derived from colchicums. in many cases it kills the
plant material exposed to it, but sometimes you get double the normal number
of chromosomes. There may be some use of radiation these days, and it's
possible that there are other chemicals that do a better job than
colchicine, but last time I looked it was still in use.
Considering that colchicine used to be a treatment for gout, there must have
been some interesting effects.
