Should be so. but it hasn't been tested.
It is also possible that it is a double recessive. So testing needs to be done. Could be it needs some genes for disconecting daylight trigger plus genes for disconecting vernalization needs. Same for Whenever Rebloomers. I do know that Forever Blue X What Again gave a huge number of rebloomers. But the reversee cross done by Terry Aitken didn't produce any rebloomers. Could be maternal inheritence of Forever Blue's plastids and plant vigour is telling factor. I'm planning on doing reverse cross with good numbers of seeds here to test in same growing conditions. Then there is Heterosis (hybrid vigour from specific crosses) which could play a role Chuck Chapman From: Bill Chaney <billchaney@ymail.

I have been following all the IMM posts and your ideas on dominate and recessive traits. So if summer rebloom is truly recessive, then it should follow that all vigorous seedlings from two sumer reblooming parents would be summer rebloomers. Is that correct and has it been tested?
Thanks
Bill

Even oncers. Plants with much better characteristics, giving a much higher proportion of quality seedlings. And just as high a percentage of cyclic rebloomers. More product with less work.
This is because cyclic rebloom genes are dominant. The summer rebloom genes in Immortality are recessive, and will only produce a summer rebloomer if matched with other summer rebloomers. The rebloom factor in Immortality is irrelevant in a cross with a cyclic rebloomers 1) Cyclic Rebloomers X vigorous plants = cyclic rebloomers 2) Summer rebloomers X vigorous plants = all oncers (unless they are carriers of summer rebloom genes) 3) Cyclic rebloomers X Summer rebloomers = cyclic rebloomes (same proportion as #1) 4) Immortality X Cyclic rebloomers = cyclic rebloomers (same as #1 & #3) but with a small proportion of quality plants.

not always. From seedlings so far, I'd say IMM isn't homozygous for these traits. Highly dependent on the cross. Wish I could figure out in advance which ones would be most likely to be good! Betty's kids (with IMM as pollen donor) and several of mine (IMM pod with pollen 3 of 4 survivors from STUNNING SERENADE, a few from the CSONG cross, all three so far from AMITY ESTATE) are nice and tall. I've had less success with substance (texture?), but did get at least one from DUSKY GRAPE pollen that had superb substance, so it is possible. Form has been all over the place, but FOGBOUND, AMITY ESTATE, CSONG mostly have good form. None so far have had super wide/touching hafts, but I've not had much pollen success from any touching haft parents yet. FOG kids are small, short stalks, but form is definitely not median retro on most that have bloomed so far. VIOLET MIRACLE does the same thing - mostly retro form, but very wide, touching hafts on seedlings from EASY LIVING. <but with Immortality you also get short stalks, poor form, poor flower texture.
