I'm looking to try a little cross breeding project for fun does anyone here know weather or not any of these are fertile? I know GC produces hips. any info on fertile david Austin's would be fantastic so i can try this out

Hello community,
I found 6 red (or almost) hips (open pollination) from my 'La Belle Sultane' which is placed underneath the bigger 'Cherry Meillandecor', did someone already have some fertile seeds from this rose, by the past or recently ? pictures attached.

La Belle Sultane has descendants listed, as seed parent and as pollen parent. Unfortunately access to the list of descendants is a privilege of supporting members.

Thank you Margaret. Yes I know about the access to that list. I asked because I know nothing about the propagation techniques and hoped for someone who could make the try of growing them. This could be a total fail of course but "nothing ventured, nothing gained".

Was not really sure how to get this question out, but thought it would be worth a try to post it here.
Does anyone know if there are companies that an amateur hybridizer could contact to determine ploidy on of their plants? I can see how having that information for plants that prove difficult to work with might be helpful.

I know that UC-Davis has a program (Foundation Plant Services) for testing for rose viruses, and although they may not test for ploidy, they may be able to tell you if someone else does. I can't provide a link, but you should be able to search using the program name.

Does all rose seeds produce different variation?
If I good understand, all seeds is different then mother, maybe that is less them one percent but it is different?
Does this correct? Thank you.

The simple answer is yes - all seedlings that come from parents that are hybrids themselves (ie all garden varieties) will also be hybrids, and are genetically unique. This is the case even if the mother plant self-pollinated its flowers. Even a seedling that looks identical to the mother to us is in these circumstances a new, distinct rose.
As I understand it, this is what separates the offspring from garden varieties from species roses, which if self-pollinated produce seeds that come true to the parent. So a wild R. Glauca for example, if it self-pollinates will produce offspring that "come true" as more R. Glauca, but if it was pollinated by a different wild species, or a garden variety, then the offspring are new hybrids themselves that are genetically different to the mother (and father) plant.
I hope that answers your question.

You're welcome.
May I ask, are you doing some rose breeding?

Yes, I get first bloom B) and that seed is from open pollinated seed and it is first.
Also I have now 10+ new plants. This 10 new is results from a couple of hundreds seedlings. I need to make more observation on both case.
Last year I don't cross anything because corona, long story...
