Re: Subject ... debates, politics and Hostas

Yes, there are-but right off the top of my head I can give a specific example.

Hosta species are all ready a polyploidic genus to begin with.  The ancestor 
that has given rise to the plants we call Hosta. Hostas have a very large 
number of chromosomes with 60. 

As plants evolve they some times tend to accumulate more genetic material 
than animals do, and thus have higher gene counts and a greater occurrence of 
polyploid species and forms.

I do not think that the use of polyploids is going to make to much of a 
diffrent in Hosta breeding-not like it has for Hemerocallis.

What looks more promising is the use of odd taxa from China. Japan and Korea.
Some of the "newer" species look to have a wealth of genetic material that 
breeds can incorporate into their breeding programs.

Since it appears that Hosta is a young genus, the species have not had the 
time to develop ways to isolate them selves from each other and freely 
With the current species existing as geographically isolated populations.
