I have a question for anyone who may know. Does anyone know what the ploidy level is of most complex Paph's (Like Paph. Winston Churchill and Paph Elfstone etc.). I am wondering if they are all tetraploid or if some of them may be hexaploid (6x).
The reason that I am wondering, once in a while if you cross a diploid brachy onto a complex most of the offspring tends to be fertile. If the complex was a tetraploid, the complex x brachy would all result into triploid plants (and you would assume that most of those are sterile). However, if the complex is a hexaploid, if you cross it with a regular diploid brachy, your resulting offspring would all be tetraploid and thus fertile.
Any ideas?
