I was trying unsuccessfully to research the pedigree of ORAvolmon, and only found the parentage given here.
Not intending to dispute the pedigree, but I am curious as to the source, and reasons for the assumption that Delbard's mauve rose, the 1970 "Vol de Nuit" might be the parent as opposed to the deep pink 2010 Reuter rose by same name. I could well imagine a good deal of cross-pollination between the two French hybridizers and their newest offerings, and (perhaps due to my ignorance) would be tempted to assume Orard might have worked with the newer, fragrant, award-winning parent, and not the 40 year older varietal with its "older HT baggage". (ORAvolmon is purported to have good health.)
Thanks in advance

As mentioned, it was only an assumption. The main reason in hindsight was probably that
- the Reuter rose was not released befoe 2014
- the Delbard rose was successfully as a parent for several cutivars between 1990-2010
Unfortunately, the source for the parentage as listed in 2016 does not seem to have been recorded.

I added this rose. My apologies for not adding more detail at the time.
I keep a diary and my notes on August 28, 2016 say (in part):
Intro Texas Rose Venture, 2015. Japan.

No apologies warranted, Patricia! All of your work is muchly appreciated.
But am I to understand then that the naming of the parent is correct, but the exact identity is very much in question?
I might try to use this in some breeding, and perhaps any offspring might give some insights, assuming success
Thanks!.

I feel sure that I entered the parentage from a Japanese website which is probably why I did not add the reference. (Orard in their website talks of an agent in Japan, but does not name them as far as I can see).

For further discussion on the the genetics of this rose, refer to WildRose's comments on the page for Basye's Purple Rose, and the two prairie rose morphs.

I am very confused about the parentage of this one.
In the comment just below, AndrewBarocco cites the breeder's notes, which state wichuraiana is the pollen parent, not abyssinica. Is there a conflicting source, or another reason why the parentage has not been updated?

I have been wondering the same.
Anybody know whence the original claim of parentage arose?

Citing of unpublished notes isn't sufficient for modifying the parentage. We would need at least some photos of the relevant notes.

I agree with you, of course, it would be better if Andrew Barocco could share this if he has access to it..
By that standard, I have the same question as Philip ATX above: what is the source for the parentage being Abyssinica? Is it in the registration?

Can you please clarify as to what source could be cited providing the claim to Abyssinica in the parentage? It seems highly improbable IMHO.

My MR12 shows GT x R. Wichuriana.

Parentage was certainly from the registration. This listing was added in April 2006. We have now revised the pollen parent to Rosa wichurana as per MR12

Thank you for that.

I guess this is as good a time as any to bring this up, but does anybody know if there is a preferred or proper spelling for Wichuxxxxx? I see HMF uses Wichurana and Wichuraiana, while the ARS apparently cleaves to Wichuriana.

The name of the class is based on the German botanist Max Ernst Wichura. (Wichura = Storm, Gale in Polish). It was originally spelled Wichuraiana by Crépin in 1887. This was corrected to the correct Latin form Wichurana around the 1920s. Wichuriana is any case incorrect.

Tropicana is still loaded in blooms after an extended period of 110 temperatures (not including the heat index). I don't know if it's the weather because she's new here, but she's been a lovely shade of peach, rather than the orange I see in so many pictures. Completely clean foliage and growing like a weed. Fragrant Cloud beside her does have a stronger fragrance and less fading, but a significantly smaller number of blooms.
Own-root, southern hot and humid Z8, full sun, daily overhead watering, sandy soil. So far, no sign of mildew!

Yes. Colors get rather pale with high heat.
