Re: JI/SI cross techniques

I doubt that heroic measures should be needed to produce most wide crosses.
If what I've seen is any indication, species hybrids are a vital, naturally
occurring part of evolution. I've never bought into the idea that evolution
in response to sudden climatic change would take thousands of years and just
the right mutations. The odds are simply against survival with such a
scenario.

It makes considerably more sense to me that plants should be able to respond
quickly enough to ensure the survival of their gene pool and what better way
than to merge with another related species, especially a stronger one, to
give the next generation of seedlings an advantage?

I'm still trying to figure out how to balance the timing and the proper
amount of "encouragement" during each phase of reproduction for each species
I work with but in all of the cases so far, I've found that the condition of
the pod parent is the deciding factor in obtaining seeds from a wide cross.

IMHO, the AIS scientific community has a lot of catching up to do. The
"testing" done by the authors of the last article consisted of looking at
the plants and trying "a few" crosses.
