It is difficult to know what is happening genetically without more details.
1) What species are the plants?
2) Are they diploids, tetraploids or something else?
3) For any cross, what did all the other seedlings look like? What do the seedlings look like from other crosses?

The concepts of dominant (and recessive), codominance and incomplete dominance work best when the crosses are between inbred lines and in particular inbred lines that differ only in the same characteristic - that is, they have been made genetically identical except for that one characteristic. When the crosses are between two completely different lines (or strains, etc.) it becomes much more difficult to assign a simple label. Without more information, particularly what do the other seedlings from the same crosses look like, it is not possible to provide an explanation with reasonable confidence.

Thanks for your input.

They are Echinopsis hybrids.

2) Are they diploids, tetraploids or something else?
Assume the parents are diploid Echinopsis hybrids(possibly erroneously?).

All are grafted to the same Cereus repandus rootstock, of the few seedlings I grafted there are only four distinctly different:

JHC L1 Choir Mistress shown in the last post,
The Pink seedling shown in the last post,
Oranje Boven,
and another as yet unnamed, with some orange and red.


The first two flowers on the left are older than the one on the right, all are on the same scion.
It appears the color changes as flowers age.

This scion is not as floriferous as the above seedling, scion.

There are still some scions which have not flowered as yet.

Provided the opportunity arises next season, am in Gingin, Western Australia, I will try crosses between all the seedlings and parents.

Unfortunately it will be at least two years before I can reasonably expect to see any flowers resulting from the crosses.
