[iris] Re: HYB: help - I. pallida crosses
Ok - sounds like you both think it might be worth having the genes, but
maybe not worth the time and trouble?
I keep piddling around with offspring from my very first pallida cross
(S1 - seedling #1), which was the tall pallida that grows everywhere
locally (Beatrice? dalmatica?) X MULBERRY ROSE. Although the few
intentional crosses with it that I've tried haven't worked, it readily
sets bee pods, most offspring that I've raised from it look pretty much
like S1 (diploid? triploid?).
Exception is S1bwh (white seedling from S1 x bee) - it looks pretty much
like a tetraploid (or 48+) and is moderately pod fertile with modern
tets. I've saved a seedling from it X VIZIER (kept the best of a
handful of similar looking survivors), plus half a dozen seedlings that
I just lined out from it X DARK PASSION. Success rate setting pods on
this one is nearly as good as other TBs here (i.e., varies from zero
success to about 30%)
I've also kept a S1bwh X bee seedling (i.e., pallida grandchild) - big
tall awkward, wide branched thing that was pod fertile in the one cross
I've tried. It's a very pale pinkish lavender, crossed it with
TRANS-ORANGE (I think...), seems like there are seedlings from it that
were lined out this spring.
Bottom line - if you trust the bees to do the work, it doesn't seem all
that hard to get fertility ;-)
On the other hand, I have not seen any bee pods on this batch of
seedlings that I dug out. They do sometimes make pollen, unlike S1 or
its seedling S1bwh. But lots of modern TBs don't make pollen with my
growing conditions, so that's not indicative of anything.
Maybe I will try to scatter them around the edges of the maintained
rows, giving the bees more access to diverse pollen for them!
Paul, do you know anybody who would especially want them?
