Rookie questions about Phal. primary hybrids Male
Default Rookie questions about Phal. primary hybrids

To make it a little simpler, I'll take an example: Phal. cornu-cervi X Phal. violacea (a.k.a. Phal Valentinii).

And now my rookie questions:
1- Is the reverse cross (violacea X cornu-cervi) technically stil a P. Valentinii?
2- I know that bloom as well as habitus variability is to be expected when it comes to seedlings, but how different could be the two crosses (cornu-cervi X violacea, and violacea X cornu-cervi)?
3- Intuition tells me that the pod parent is likely to be dominant more often than not. Am I close?
4- In the "classical" P. Valentinii (cornu-cervi X violacea) is cornu-cervi the polen parent and violacea the pod parent?
5- If one of the parents is fragrant, is it more probable to get a fragrant cross when the fragrant one is the pollen/pod parent?

I am really curious.

I can't answer all of them but for #1 the reverse cross or reciprocal cross is the same cross. So (cornu-cervi x violacea) and (violacea x cornu-cervi) are both P. Valentinii.
I read a post somewhere on this site that they don't add the reciprocal cross on the registry. They register whatever one is submitted first. So they don't need to list the reciprocal cross on the registry because it is automatically P.Valentinii. (Or whatever cross they are registering).

For #3 I have also heard that the pod parent is more dominant. But again that is just what I have heard.

As for #4 the first listed parent is the pod parent and then the pollen parent is listed second. Hopfully everyone prints their tags right.

That is all I can answer. I'm sure someone else will give you some more answers.

Thank you, Wynn Dee.

So the first listed parent is the pod parent. (Repeat after me: "the first listed parent is the pod parent".)

I find it a little counter-intuitive that the reverse cross or reciprocal cross is the same cross - but it's a valuable info for me.

#1 Yes it's the same grex name
#2 and #3 Since half the nuclear DNA comes from each parent it should not make a difference, but there is a BUT...nuclear DNA is not the whole story. There are also mitochondrial and chloroplast sources of DNA. 100% of both of those come from the pod parent. Since mitochondrial DNA controls the plants energy use, the vigor can be much different. Chloroplast DNA influence is not always visible to the grower, but most foliage variegation results from it so only a pod parent controls variegation. Mothers are not necessarily dominate in humans or plants in terms of nuclear DNA.
#4 The first listed parent is traditionally the pod parent, but no firm rule exists that I know of
#5 I doubt it matters since fragrance is most likely a nuclear DNA trait...however fragrant/not fragrant is not necessarily a single gene trait or a simple dominate/recessive trait so I think it might be hard to predict. That's just guessing. Someone else may have facts.
