HYB: 201 Homework -- Ivory Ground
More observations of SOSTENIQUE
X TRIBE OF JUDAH seedlings....
The basic ivory ground pattern is:
Standards -- yellowish-ivory, with a =
yellow flush along the midrib and =
sometimes fine yellow veining. =
Style arms --yellowed-ivory, with a
yellow flush along the midrib. =
Falls -- yellowed-ivory, sometimes
with a yellow flush on the hafts.
Here are some examples that survived
two selection cycles:
S.Pale ivory. =
F. Soft lavender-grey, with stippled
violet signal and rust-on-ivory veins
flanking the beard.
S. Yellowed ivory.
F. Soft plum, with near-solid burgundy
S. Soft medium violet
F. Soft medium violet, except for
yellowish-ivory thumbprints on each
side, small violet camouflaged signal.
S. Soft reddish violet.
F. Soft reddish violet, with stippled
S. Soft yellowish-ivory.
F. Yellowish-ivory, with rim of soft plum, =
plum veins extending from tip of the =
beard to the edge of the falls, and rust-
on-ivory veins flanking the beard.
None of the ivory-ground patterns were
ultimately selected for introduction. Each =
of these examples was selected as the =
best of its type, but in some cases the
plants didn't meet my gardenability criteria
for introduction and in others the aril traits
simply weren't prominent enough by =
comparison with other patterns. =
The original question was how can you
predict what quarterbred seedlings are
going to look like. In other words, how
can you tell if a planned cross is likely
to be a good one.
We've prepared charts, compared traits,
and made predictions. Now it's time for
reverse engineering [for the compulsively
logical] or to exercise the artistic eye [for
those who hate charts.
None I've described were pure ivory or =
ivory and yellow, but rather were the basic
ivory ground pattern overlaid with the =
anthocyanidins -- so it's time to look at
the interaction of the two patterns.
1. Three of these correspond to blue-violet-
on-white-ground patterns I described earlier.
2. Two have patterns not represented in my
earlier post. Describe what those patterns
would look like with a white ground instead
of the ivory ground.
Are you beginning to see why I think it's a good
idea to repeat this cross, even though I've =
grown so many seedlings from it and =
introduced four of them?
More to come....
