Re: Project for large rose hip X R. Pimpinellifolia. Questions..

Hi Sebastian,
Of all the hips I've handled, the only ones that make my mouth water are from Rosa roxburghii. The fragrance suggest something like peach or apricot.

Coincidentally, I once pollinated a very double Roxburghii by 'Doorenbos Selection', a reblooming Spinosissima with purple-red flowers and purple-black hips.

The cross succeeded, to the extent that a hip formed containing seeds. Unfortunately, I was too anxious to open it, so I don't know for sure that the seeds would germinate ... and if they would, I can't guess what might have come from it.

Modern DNA evidence suggests that R. roxburghii is fairly closely related to R. hugonis ... much closer than most people would imagine.

A slight tangent from this. Is spinosissima difficult with moderns? Toying around with the idea of lavender/purple flowers turning into black/purple hips.

Hello Sebastian,

have you thought about the special combination of rosa Moyesii with rosa spinosissma? Or rosa sweginzowii with rosa spinosissima. I am not sure if the seedlings will be fertile but if it works, you would definitly get some spectacular hips...

The problem though might be that if this kind of fertilisation works, it might take two years before the seeds will germinate and I have no idea if the seedlings will be fertile/producing hips But it might be worth the try.

No apologies necessary at all Sébastien. :)
And thanks for the kind comments.

But no need to be jealous - this hybrid suckers very well, so you can grow it too!!!
Although it has been sterile for me so far, I never say never 100%.
Maybe you will be the one to get it to succeed. I would love to see that!

I've sent my e-mail address by PM and look forward to hearing from you.

Thanks, Sébastien, for the excellent thread. I, too, am interested in the edible hip pathway although I am not currently pursuing it. I love the idea of getting more anthocyanins into rugosa rose hips. One of my spinosissima cultivars, I can't remember which one but maybe Seager Wheeler, has pitch-black hips.

After a century or two of breeding we should be able to turn the rose into a choice edible fruit!

Aie; sorry about the "certain"; I am not a native English speaker, so it can happen I used that word without knowing some negative connotation. I really didn't mean anything wrong at all.
I'll admit I was jealous about that rose you have, though !

At this point, after some research and some comments here above, I'll just stick to 3 roses for now: R. Pimpinellifolia (I prefer the sound of this name, rather than "Spinosissima"...) - R. Villosa - Basye's Blueberry rose.
Of course, I'm interested in some of the other roses mentioned - 'Sweet Hips' or those from Morden, but they don't seem to be available to the first amateur newbie like me.

Not too surprised that the R. Pimpinellifolia X Rugosa is sterile, unfortunately, but I love that this rose exists.

Thanks for reaching out, and thank you for the picture !
Talk soon.

Sébastien

rugosa X spinosissima.JPG
Hi Sebastian, I am that "certain Thomas Silvers"!
Thanks for the chuckles - I've been called much worse names. ;)
I've tried to attach a picture of the rugosa X spinosissima F1 that I still have. I did the cross in the past with normal spinosissima but this particular one is from 'Double White Scotch'. I was hoping I'd get a double flowered F1.

I also have to tell you the bad news that it has never set a single hip in probably two decades. It is most likely triploid. I still hold out hope that I can chromosome double this one to get a hexaploid which would hopefully restore fertility and hip production. I tried fedtschenkoana pollen on it this season but that didn't work either. Maybe the pollen has some fertility but I haven't really tried it.
I look forward to seeing what you can do with hip improvement. I've always thought that was a great idea!
Best wishes, Tom

Thanks a lot !
I never heard about R. Laxa for hips consumpton, that's precious information...
There are some R. Rugosa x R. spinosissima out there already ? Oh man...
Yes indeed: breed by a certain Thomas Silvers

Thanks to all.

My suggestion is 'Suzanne' or Rosa laxa x R. altaica or R. spinosissima. 'Suzanne's' hips are dark red, likely because of the influence of Rosa spinosissima in its pedigree. However, in my experience 'Suzanne's seeds can be difficult to germinate.

Rosa laxa has a much better flesh/seed ration than Rosa rugosa hips, so I would keep that in mind.

Rosa rugosa x R. spinosissima seedlings are invariably extremely prickly to the point of being vicious.

By the way, I recall eating Rosa villosa hips many years ago at the Brooks, Alberta Horticulture Research Centre, now the Crop Diversification Centre South. It was like eating jam off a tree!

I'm trying this next year.

Stephen, just collected my first Dr. Eckener hips.

Also. Just bought a plant of Dr. Eckener. According to HMF - a tetraploid HRug.

FM3 should be RSM K1

Re: Project for large rose hip X R. Pimpinellifolia. Questio

by johannes Pl » Thu Oct 12, 2017 6:38 pm

FM3 is a tetraploid, half Rosa rugosa. Perhaps be a chance the large hips could be recovered in one cross. From Morden Canada. Johannes

Re: Project for large rose hip X R. Pimpinellifolia. Questio

by Johannesp » Thu Oct 12, 2017 6:21 pm

I think the name is FM3. A tetraploid 1/2 Rosa rugosa. One could breed out the Rosa rugosa. The plant is from Morden. J

I am also interested in the idea of breeding for hip production.

You may want to check out the rugosa, 'Sweet Hips' (not listed on HMF yet).

Thank you Stephen, it seems like one of the best option indeed.
That one and Rosa Villosa (aka Pomifera aka Apple rose), which is also Tetraploid, should be excellent match for my project.

Basye's Blueberry produces hips with lots of flesh and few seeds. Potential to produce lots of hips as well. I've grown it for years.

The pentaploid 'Magnifica' is the Hybrid Rubiginosa.

The Hybrid Rugosa 'Magnifica' is the triploid one.
