In search of…
Thanks Kim, always to my rescue with answers
You’re welcome David. Fortunately, this one I KNEW! LOL!
In Search Of
Had to ask my wife on that one.
Hi Joe
I have only recently realised that I have a completely thornless seedling bred from modern roses. It is a cross of Heaven Scent as the seed parent which has few thorns and almost none on flower stems. The pollen parent is Nocturne from the 1940s. Both are HTs sorry so don’t fit your OGR or Species quest. I was just showing my mother the plant and the four grafted 1 year old versions that I was planning to pull out and give to her when I realised there were few thorns. On closer inspection I could not find a single thorn on any of the bushes. Needless to say I am now keeping all of them and will see how they go. It is also perfumed and disease resistant. I just didn’t like the way the flower opened so maybe I need to re-evaluate my decisions on discarding seedlings… I can’t find a recent photo top show you and it’s pruning time here in Australia. This is the photo of the original flower.

Larry,
Were you referring to the miniature or climbing Pink Cloud? Thanks.
The one from Ralph Moore-multiflora type with long canes. I’m traveling now, don’t have more details at hand. Pink Clouds (plural word) I may have mistyped before. I got one reblooming seedling last spring, all others no early flower.
In southern British Columbia I have seen what I think could be an exquisite Rosa Canina…totally thornless…amongst nearby very thorny shrubs of what appears to be the same species. It happened to be in the fall so I haven’t seen it bloom…perhaps this spring. I was so impressed with the attractiveness of this shrub…impressed me the same way Lillian Gibson does with regards to the smooth, tall, reddish canes. The hip display was reason enough to grow this plant. Would I recommend it…mmm…how brave are you?

Canina is not the most compatible with my climate but that’s an attractive load of hips in addition to the thornlessness. The pollen would very likely not contribute much to the offsprings’ likelihood of inheritable thornlessness, or would it?
I don’t think it would make much difference if used on another canina, since they all but disregard pollen. Used on a normal diploid, triploid or tetraploid, I’m hoping it would help reduce thorns, since I’m trying R. corymbifera ‘laxa’ for the same reason.
Degree of prickliness is said to be a quantitative trait, but I don’t know whether there’s anything other than canina meiosis that could skew it towards favoring pollen or seed parent. There might be.
It stands for “In Search Of” David.
