It would seem that little has been done with the species nutkana, with the notable exception being Schoener’s cross w Paul Neyron, a “modern” tetraploid. Has anyone here used nutkana pollen on diploid parents? I am thinking about making a few attempts this season, but would like to hear if anyone else has made such attempts, and if anything came of such.
Let’s hypothesize capturing rebloom.
Nutkana pollen onto ‘Mutabilis’ results in RRRr tetraploid offspring, all once-blooming.
The tidiest-grower with good health gets crossed with a healthy modern rrrr, with resulting RRrr and Rrrr offspring? Is that right? I’m making the Punnet square in my head and coming up the same each time, and it doesn’t seem right.
I’ve used it a little bit, several seed grown plants from https://sheffields.com/ they’ve only been flowering the last two years so not much to report on. I’m not super sold on nutkana, may just be my plants, they don’t do well with heat or drought conditions, do have some degree of foliage scent though.
RRrr or Rrrr would be correct theoretically, doesn’t account for if things like preferential pairing happen or any of the other oddities that could happen.
I should send you seed from here on Vancouver Island; this population is VERY heat and drought tolerant. We have almost no natural precipitation during the summers, with increasingly uncomfortable heat domes, yet the wild roses do their thing magnificently.
I used Schoeners and R nutkana as seed not pollen parents because both hardy in my north garden.
Hail took care of both types of hips this past year.
In 2022 used R nutkana as seed parent, and obtained seven germinations on 2nd or 3 rd cold cycle. After euphoria of germinating turned into wretched wiry thin seedlings. Think down to one outside for first winter.
Be interested hear results as pollen parent.
Post Script
I fact checked my records … always suggest keep your records no matter how tedious
Germinated on “4th” cycle on May 20th +/-
R nutkana (hexaploid) X mixed pollen of Prairie Peace and Hazeldean - mix of tetra and triploid pollen
My back cross of Schoener’s (? pliody?) X Nutkana never germinated.
Seeds went below zero -2C on Oct 22 for 1 cycle. Raised to above zero ~ambient (17C) Jan 30. Back down after ~ 2weeks (end of 1st cycle) and up to ambient again after 2 weeks. Repeated 3x more until May 20 germination.
This below 0C approach is frowned upon by conventional hybridizing wisdom.
FWIW, all my seeds are out there in that. Febrrrary seems to be giving us ALL THE WINTER at once, here on Vancouver Island…
I hates it.
Hahaha … saw it in your post.
Divine guidance on how to stratify tender x hardy or hardy x tender crosses … or in my case going for the germination 6 Nations clutch play ruby solution.
Definitely proves exposed to below 0C for a couple of days. Try 90 days, just kidding. Hope they weren’t tender x tender the pundits will have field day if for days.
Real estate market would crash to realistic prices.
-26C this morning, no doubt you experience in your past High Wood river area history?
I regularly endured -40 days as a child. That far north, “Snow Days” happened only when the pipes froze. lol
I am growing and intending to cross both hardy and “tender” (tenderest being ‘Mutabilis’, perhaps?) kinds of bush/shrub roses. Realistically we have to acknowledge that extreme climactic events will continue to increase in frequency and severity, and I believe that some form of “survival of the fittest” via attrition has some value in any program going forward.
That’s also why I keep thinking of using the native species from the Island would help, especially in the development of deep roots to penetrate the rocky soil.
Grew mutablis both in/out door. Found one by fluke recently at CTC - must of been destined for Lotusland. Tried indoor, gone by spring. Outdoor one lasted longest ~ with lots of peat moss cover. A favourite for a warmer climate.
I freaking LOVE it. As you can see, it’s a halo around my head in my profile picture. And here is a picture of what it looked like just before it started snowing:
Holding some foliage from last summer, and bursting forth bright new growth everywhere. Le sigh. It will likely loose some of the tender tips, but should be magnificent again later as always.
