Re: More genetics

It's important in our hybridizing discussions to not confuse colors and
patterns. e.g. plicata is a pattern, not a color. Some patterns have an
assumed color association: we tend to assume an amoena is white/blue, a
variagata is yellow/red, a neglecta is light blue/dark blue.

Pink plicatas are real and you can segrigate them in the F2 of pink X
tangerine bearded plicata crosses. There are a number of good ones around.
PINK FROTH and PINK CHARMING come to mind.

Sharon asks if dominant amoena is not an inhibitor for blue. Just right.
Dominant amoena has the same effect on the standards as the dominant white
gene has on the entire flower. I am still interested in any "modern"
recessive amoenas anyone might mention. I have done the geneology of
SOSTINIQUE and can find no recessive amoenas in its background although it
does have dominant amos on both sides  as well as carotinoid amoenas through
LATIN TEMPO which has PINNACLE three generations back. I also researched
GALLANT ROGUE attempting to find where the light ring around the falls came
from. Registration descriptions may not be completely helpful. I suspect the
ring was not recorded for SNOW PEACH and perhaps some others. Into the
vintage color catalogs to check this out!

Interesting that Sharon's SOSTINIQUE X aril cross came up with at least one
seedling that was white with a blue ring around the falls. Sounds like the
classic EMMA COOK pattern. The results of tall bearded x aril crosses are not
easy to understand in part because there is apparently no intermixing of the
two sets of chromosomes. This is why a tangerine bearded pink aril bred is
not a likely accomplishment. Any arilbred which has four chromosomes each
carrying the recessive tangerine factor is going to be tall bearded for all
intents and purposes and will not look aril enough. We need to realize that
Tall Beards and Arils are very, very different genetically. In fact, they are
barely related enough to cross at all. I believe some have suggested that
Arils should be in their own genus.

Clarence M. Just how much is a copy of the original Dykes Genus Iris worth
these days?
