RE: [SpaceAgeRobin] RE: SA inhibiting seedling

Neil, Patrick Orr posted a picture of my seedling 16-31 on Iris Photos.  It was selected as best seedling of Region 15 at the spring trek in Tucson.  That was partly because it is late and all the earlier ones were past their prime bloom, but it is a nice iris.  It is from Conjuration X Purple Pirouette (SA X non SA)  and is the only survivor of seven siblings none of which had any SA expression.  I think it would be a much better candidate to test for the SA inhibiting factor than the Mesmerizer seedlings.  It doesn’t have pollen here, but last year it set a bee pod, which I discarded, so it should be pod fertile.  It has Conjuration’s branching and growth habits  It’s biggest fault is that it is not rot resistant.  However it multiplies rapidly and blooms consistently.  I am seriously considering registering it and getting it introduced.

 

I would much prefer sending it as a test iris for this project rather than any of the Mesmerizer X 21-15A seedlings.

Neil, another of the Mesmerizer X Pink Champagne cross just bloomed a two tone blue with nice horns.  Pink Champagne should carry SA genes as one of its parents was a space age iris.

 

The parent of the non SA bunch (Pink Lenox X Celebration Song) is a nice deep pink-orchid.  It’s very pretty, often well branched and adequately budded, but it has serious faults here.  It is subject to pineappling and bloom out.  I just returned from the Region 15 spring trek in Tucson where it was blooming beautifully in two guest gardens and the worst case of pineappling I ever saw in a third.  I’m still trying to figure out what horticultural factors may influence that problem.  I might consider sending some for the SAGE project if you could treat it as a guest, report to me on how it grows for you and agree to destroy it if I decide it is really undesirable.  It is pollen fertile, but its seedlings are terrible, poor colors, poor form, poor everything but growth.

Francelle, don't be to quick on discarding those non-SA's you mention:

 

Francelle reported: "My Mesmerizer crosses have bloomed fourteen plants with only two showing any SA appendages.  Mesmerizer crossed with one of my seedlings (Pink Lenox X Celebration Song) has bloomed six plants with no SA qualities, or any other for that matter, and they are out of here."

 

One of the possible explanations of the appearance out of not-quite-nowhere of the first SA's plus some other anecdotal data is that there is a suppressor or "normalizer" genetic element covering up SA performance in some varieties.  You may have stumbled across such in the cross of (Pink Lenox X Celebration Song)--or it may be the conditions weren't right for SA traits to show up--as in the example of Devonshire Cream. 

 

DC had no space age characteristics for Suttons until moved to soil with higher pH.  I regularly has them for Bill Burleson, and occasionally here in my soil, wavering between acid and lime-rich neutral at best.

 

One of our test-cross types is aimed at discovering these--with the fair degree of certainty that ROMANTIC EVENING is one of the target varieties for the inhibitor, or whatever it is.  WILD WINGS probably has it too.  Mike Sutton reported a short list from his memory of others, including QUITO, DYNAMITE  and others that give few if any SA offspring.

 

Your seedlings may be sources of information about this matter.  Since Mesmerizer is a parent, the other seedling may be one of our possibles that carry a no-SA's-in-the-F1.  Would you be willing to share that seedling, or any of the non-SA progeny from the cross with Mesmerizer?  They could yield important information for us.
