Need parentage for Blc. Goldenzelle 'Passion'

[cirillonb]

Don't quote me on taxonomy, but I believe the names in single quotes are called cultivars. I suspect the parents were hybridized by cross pollination. With such disparate parents, offspring can be the spectrum from one parent to the other and combinations of the two I suspect these two parents have been cross pollinated by several hybridizers since there are so many offspring. Literally pages in OrchidWiz with the same name Goldenzelle but numerous quoted names, ie, cultivars.
I doubt cloning had anything to do with it up to the cultivar stage. Breeding true after that may have entailed using cloning techniques.

someone with more knowledge, please jump in and help my naive explanation.
