Pollen parent: MM 15-45b (M. villosa 'Zoe' X neopavonia 'Summerfield')
This is a sibling cross between two offspring of MM 15-45, a cross between a brightly colored flower and a spotted one. None of the MM 15-45 flowers had spots on them. Breeding them together is supposed to bring out the recessive genes, so that's what I tried.
MM 19-17a. The first offspring of that sibling cross looked a lot like its parents: no spots (I guess that's why they call the genes recessive).
I am very happy about the way this one looks, and almost equally happy with what I learned from it. I’m pretty sure the spots are recessive, so to combine this look with a new background color I need to cross a spotted flower with a colored flower that I like. The children of that cross will not be spotted. This has happened repeatedly, and it puzzled me for a long time. But those plain offspring apparently carry the spotted gene as a recessive. If I cross those children (which I did in this case), most of the grandchildren will not be spotted, but a few will have spots and the new tepal color.
Now that I understand what's going on, I should be able to breed spotted flowers more reliably.
