biversatas

From: Bill Shear <BILLS@hsc.edu>

I grew several biversatas [versicolor x (versicolor x ensata)] over the
past three years.  They came from SIGNA seed.  Generally they were
disappointing because they all appeared as pure versicolor but blooming a
little later than usual for that species.

That would probably not be the case with named, selected varieties.

Versicolor has so many chromosomes, I suspect that the ensata genome gets
"crowded out" by meiotic drive in just a few generations, and you get what
is essentially pure versicolor.  So it would be neccessary to select
rigorously for those that show ensata characteristics.

Perhaps Sharon can speak to this but I believe it can also happen in
arilbreds, where the onco or regelia chromosomes segregate out in
successive generations.

How come you never hear about "gruntled" postal employees?
