A lot of variability - in the 40+ surviving seedlings from Imm X Csong,
1 produces tons of very fertile pollen, 4, 10, and 26 produce good
anthers & pollen unless it's been an exceptionally stressful spring, not
sure about 3, 11, 15, 32, 33 or any of the higher numbers (they got
tossed without being used). Seems like 31 is a decent pollen producer.
In that same cross, 1, 4, 10, 31 are short, 3, 7, 11, 26 are tall (well,
Other first generation seedlings haven't had a lot of surviving
seedlings (usually because very few have germinated in most crosses), &
anther survival has been unpredicable. I have the impression that once
I get two parents together that are good anther producers, all the kids
make good anthers. But haven't kept notes. If the Imm kid has the same
anther problems that IMM does, it carries on. It doesn't seem to
average - either the kid has the ability to make good anthers or it
doesn't - on or off.
Height does seem to average more than I used to think. Pretty
impossible to know without growing for 4 or 5 yrs how much is climate
effect (phenotype) and how much is genetic potential. Imm is always
short, some of her kids are always short, but some are quite tall.
Lousy form, but all the Imm X Above the Clouds kids (4 or 6?) were quite
tall. All the Imm X Dusky Grape kids are very short, & DG can be taller
than I am (before it falls over) in really luxuriant growing conditions.
In general, the more generations into a breeding line that started with
IMM, the taller each generation seems to be, but that's because the
things I've been mixing in are tall (or registered as 36" or more - they
can be <very> short here, shorter than IMM).
So far, most (all?) of the Imm kids I've bred back to Imm have been
short. I can't think of any tall ones.
The stalk/fan ratio has been surprising - so awful (low) in Imm, but
ranges from near bloomout & 1/2 all the way to being as weedy as Imm,
first generation and on down the line. So far, I've not noticed any
pattern in which crosses make lots of little fans, which ones make fewer
blooming sized ones.

Just wondering how long the 'Immortality' genes seem to have an effect on the
seedlings? We've talked before about the shriveled and black anthers and the
short stalks. Some of you things are only a small percentage Immortality so I
wondered if you are still seeing the results.
