Thank you!!
I don't know the parentage of mine. I bought it as a seedling with no info about the cross they did.
One of my first orchids was a C trianae seedling which was a cross of two alba forms, and the flowers turned to be purple. At that time I read about genetics of the alba forms: the gene C that makes the plant produce chromogen and the gene R responsible of the production of the enzyme that converts the chromogen into anthocyanins (that make the flowers haver color).
I mean, for instance, ccRR and CCrr are 2 alba forms but if you cross them you will get 100% colored flowers.
But this C wallisii,
is not an alba form. It has very light purple tones (specially in the lip). I think they call it
forma amesiana in Brazil.
Half an hour ago, I searched a little bit and found an article (see below) that states that very lightly colored flowers have another allele: that of dilution D. (D: dense coloration, d: diluted)
So, if that article is correct, the genetical constitution of a plant like mine should be:
ddCcRr (or other, but always starting with
dd)
So it seems that I can't get stronger coloured flowers after all... I will always have dd in the selfings.
