Most successful miniature roses in breeding

The reason I was asking about the parentage of Paprika, is that it looks every bit like a Hulthemia Hybrid to me!

Do some Hulthemia Hybrids have a yellow blotch instead of a red/crimson blotch?

I dont believe so, George. The Hulth dot seems to be red-factored of some sort.

BTW, another reason I like to use Baby Love is that it is one of the few roses I know in existence that can pass on true crayon orange coloring. A lot of miniatures are void of much orange ancestory, and a lot of what is present comes from Zorina, Gingersnap and Gold Badge. I am amazed mini breeders have not tried something to the effect of:

[“Well-Formed mini #73826” x(Carrot Top x Baby Love)]

…or some such other combination.

George, yes, I think Jadae is right - the Hulthemia blotch is the overlay of pigment on the background that may be white or yellow. A yellow eye represents a lack of overlying pigment.

I do have some hybrid Hulthemias that lack the typical blotch and have a yellow eye, but I think that represents either an overpowering rose gene (dominant to the blotch), or simply an absence of the blotch gene.

Thanks Jim and Jadae.

If I could, I know I would try to pair up some climbing miniature variety with a Hulthemia hybrid, to try and develop miniature climbing Hulthemias. To me that would be really cool to experiment with!

If you try that, my advice would to be sure that at least one of the parents passes on mildew resistance. That type of combo feels like it could easily have the potential for mildew proneness, especially given the ease of a lot of vigorous, green growth.

Hi Jadae. Hmm that’s interesting you say that, ok…

I wonder if anyone here can nominate a favorite climbing mini they like to use in their breeding work?

I love the full cascading effect minis create as weeping standards…I don’t see enough of these around in our gardens here any more these days…alas!

I am not breeding minis nor climbing ones but Warner keeps using Laura Ford.

This past summer I planted 6 different varieties of the Oso Easy Roses. Paprika was (by far) my favorite. It was totally clean this summer, the foliage was nice and dense, and it had fast recycling of bloom. In addition, the color was more vibrant than most of the varieties, although the color does fade. I did not try it as a seed parent, but I used the pollen with some success. Paprika (for me) is an example of one of the new roses you try each year that actually seems to hold promise for breeders, although the true test will come when I see the offspring that result. Although Paprika is classed with the ground covers, I think that the general size of the foliage and bloom lends itself well to work with miniature roses. It may transfer some disease resistance into a group that tends to lack this characteristic. I used it with some of my miniature/large rose hybrids of mid-size and I am looking forward to seeing what might result.

While I have limited experience working with miniature roses, I can mention some of the mini’s I have tried that exhibit at least some female fertility. These include Gizmo, Tiddly Winks, Coffee Bean, Santa Claus, Jeanne Lajoie, Denver’s Dream, Jilly Jewel, Gingerbread Man (only a couple hips), Orange Honey, Fairhope, and Little Tommy Tucker. Jilly, Denver’s Dream, and Orange Honey produced a decent number of seeds/hip and Gizmo seems to cross with just about any pollen (although some of this may be self-pollination). The others crossed pretty well but didn’t produce as many seeds/hip.

Julie Overom, ??? that much is limited experience? You are making me feel insignificant.

Hi Henry,

I received Gizmo (by mistake-wrongly ID’d cultivar) 5 years ago. I put all kinds of pollen from larger roses (mostly Canadians) on it just for fun as I really wasn’t interested in miniature cultivars. Most of the seedlings were extremely black-spot prone and were tossed, but three I kept and used for further hybridizing. I now have several mid-sized seedlings with greatly improved disease resistance and winter hardiness. However, the bloom quality and rebloom could be improved. The thing I like about mini’s is that they tend to have an abundance of these characteristics. They also tend to have a moderating effect on plant size. So it was just this past summer that I expanded my collection of miniatures. I just finished collecting my seeds for this year, so the fertility of all these cultivars is fresh in my mind. Given my experience with Gizmo I’m looking forward to seeing what these roses produce.

If I were to work with climbing miniatures, I would definitely choose Moore’s 0-47-19 as the seed parent. (R. wichurana X ‘Floradora’)

‘Jeanne LaJoie’ is the original Leafless Wonder here in my climate, so I would never choose that as a parent. Although it is an unknown as breeding goes, I would consider ‘Magic Dragon’ as a seed parent for its vigor and ability to set seed readily. ‘Magic Wand’ is, of course, a superb breeder and I feel that it has abilities that go far beyond what Ralph Moore used it for. In my opinion, it should be used in unconventional crosses to see what it can really do. It is one of only a dozen or so Blackspot-free minis in my collection, out of about 450 varieties I grow.

I have a white climbing mini of some sort, but I can’t identify it. One day I hope to post a picture of the flowers to see if anyone can help put a name to it. It can scale a wall 2 stories high when fully mature. It sets lots and lots of tiny red hips, usually containing one seed in each. I germinated some OP seed (embryos… whatever) but I don’t like using unidentified varietals in breeding if I can avoid it.

Paul, HMF doesn’t give much plant detail on Moore’s Hybrid Wichurana ‘0-47-19’.

What sort of growth dimensions and habit does this hybrid possess, and how big are its blooms?

George, I posted two photos of the rose on HMF. Once upon a time I had photos of it there but they had vanished, as did some of my comments :frowning:

Please see the link below for much more detailed info.

Paul Barden!!..OHHHHHH… Your website is totally cool cool cool!!!

Also, that wonderful picture of Mr Ralph Moore you just posted on HMF showing him at work with his masterpiece ‘0-47-19’ completetly knocked me out!
