Re: HYB: Traits/thoughts

Interesting thoughts from everybody.

What I really want to know about stalk height applies to both rebloomers
and once bloomers:
===== can you get tall seedlings from short parents?

I only have one cross that gave me a lot of surviving seedlings, enough
to compare stalk heights.  One parent was registered 37 inches, the
other registered 30 inches.  The tall parent is usually less than 37
inches tall, but I haven't measured it.  The short one is usually about
30 inches (also never measured), but has on rare occasion been a bit
taller.

The 15 seedlings that I kept for evaluation from this cross measured 26
to 33 inches - some of the shorter ones were the most variable, so might
be taller in good conditions.  Average height = 30 inches.  6 seedlings
were shorter than 30 inches, 9 were taller.

From this one example, I am guessing that shortness is a dominant trait,
but I don't know stalk heights of the other 25 or so siblings that
rotted or were discarded.  I do remember one being much taller than the
others.

And if you guys are right, that hybridizers of rebloomers aren't really
trying to get short stalks, I guess that's more evidence that shortness
is dominant.

On the other hand, there do seem to be quite a few tall blue & purple
rebloomers - most of the ones I know are descended from VICTORIA FALLS.
