Thanks was succesfull too.
Had a few time to google.
Oh well, I think it is not a selfing, because the one plant had 6 flowers at that time and only the pollinated one get a pot on and the second plant she had 4 flowers and only the pollinated one had seed.
This year the same with this 2 slippers and with japonicum as pollinator. But only a few seed this time.
So the chances is every time there but I cut when they open the pollen to ensure she cannot do it, but the chaces is there that a few of the are from a different pollen.
But I think this is true for all crosses. But what else would you do.
Cut the pollen cut the pouch down at this flowers so I see not more possibilitys to protec them.
Was using a plstic bag like they do it in the pollination of barley and other kinds, but often the steam broke.
Hope the flowers will prove it.
It maybe happened before. We think the last years that the cross of reginae and Acaule which is called Prof robatsch is maybe not the cross of the 2 Kinds.
If you look at the cross of pubescens and Acaule you see the influence of Acaule and when you look at robatsch it looks more like a flavum alba.
So it is hard to prove it.
We have seed made out of reginae and Acaule again, but till now my friend have no answer from his lab if it worked, so we are waiting and in some years we can tell if it worked.
The only thing is that the crosses with Acaule are not easy to make.
We will see what comes out in 5-6 years.
