Many years ago I enrolled in a one-on-one "Readings and Conference"
that involved learning how to prepare slides and count chromosomes.
Accurate for sure, but NOT at all easy.
Perhaps a simpler, and perhaps not even a slower, way would be to
cross the unknown with a few known diploids and tetraploids.
Whichever type produces plump pods--that aren't balloons--defines
the type for the unknown.
With the intensity of color of the cv in Mike's photo, I would doubt
the unknown is diploid anyway. It takes dosage effects and/or
aphylla ancestry stirred in to get that rich a color tone. That's a
tetraploid issue. TB anthocyanins don't run that deep in diploids in
either BB or Bb levels--that is to say, in any diploids I ever saw or
grew. I can only speak from my own observations.
