Yes! Definitely. This is what I try to do (well, at least that's the
plan). Best example I know is STAIRWAY TO HEAVEN, a weed for nearly
everybody, out of poor ol EDITH, who has been bashed so many times by us
for poor growth/survival, I feel sorry for her.
<'Course, you have to keep those lacking in vitality alive and
producing in order to get the offspring.>
Yes - and that is the problem I am going to start encountering now that
I think I have gotten at least seeds from all the 'baseline tough'
outcrossing children of my own.
My goal used to be to collect a few tough survivors in a variety of
colors and patterns that I like. I was more than happy to let things
die and replace them with something that might do better. Now my goals
have shifted towards hybridizing 'improved' tough survivors, which means
I face the challenge of figuring out how to get viable pollen to put on
my tough children.
If it's true that loss of pollen viability is the first indicator of a
stressed plant, I am going to have a steep hill to climb (perhaps
literally, to get to the new, less frost/drought prone "garden" on the
ridgetop)! Wimpy, or rot susceptible plants rarely carry pods to
maturity for me, so that's not a good option either. Rats. I wish
there were somebody out in iris heaven with more time on their hands
than space to grow irises who would do 'crosses for hire'. Grow the
pods to maturity, then send the seeds here.
<In any case, inbred or linebred parents are nearly always good to work
with. The results you get are likely to give you more information
because you aren't working with as many unknowns. It's easier to guess
about what may be working or not when you see the results. Like working
with purely dominant or purely recessive traits, some of the guesswork
is reduced.>
Right, that's the point I was trying to make about line/inbreeding in
iris heaven. Makes it possible to do the lovely things they do,
identify and segregate the genetic lines that have those traits,
<whether or not> they would grow well here.
