Thanks Julie,
Julia Childs does look promising, I

If you’re breeding for yellows one rose you might want to consider is Bella Renaissance. As a garden rose it is perhaps my best yellow with good resistance to BS and PM along with abundant rebloom. My garden is usually torn by BS by late July but Bella show’s little susceptibility. It is also Z5 hardy.
I have used it both ways but as a female I found seed set less than I would have hope for. On the other hand two of my best crosses in the past few years have come from Bella. I have no idea what the backround of the rose is. Perhaps someone with knowledge of Poulsen’s work might know.
Thanks John,
It’s good to know you’ve had good luck with it as a parent and it’s disease resistant too. Another one to put on my list to check into.

Hey Steven! I ordered it because of the lineage and because I needed a mid-sized yellow for my HT bed that was low maintainence. It’s listed as a floribunda but it is similar to Freedom being that it really walks the line between floribunda and hybrid tea. I find this good because it often means that the branching habit it good. Also, I wanted it for breeding, lol. But beyond that, Pickering has a habit of letting European releases disappear without a trace and I didnt want to gamble on it disappearing without giving it a try. Oddly enough, I was going to order from Pickering but it magically appeared on Hortico’s list. I couldnt find a 3rd from Pickering that I was set on so I ordered Toprose, Rotary Sunrise (new from Fryer’s) and Ilse Krohn Superior from Hortico.
Hi Paul,
It will be interesting to see the color range of the seedlings coming out of Julia Childs. At this point I am not sure if the yellow will be fading or not, and my germinations are just beginning. I see the bulk of my germination occurring between 3-5 months, and then I usually don’t get a chance to check my seeds again until fall (I just leave them in the frig). At that point I have seen a number of seeds from Golden Holstein and Goldmarie that have germinated during the summer months but are too etiolated to rescue by fall. I think I read a long time ago that seeds from Golden Holstein required quite a lengthy stratification. Also, with respect to Golden Holstein, the black spot resistance was not good. Goldmarie is a better plant, but I have reluctantly decided that it is not the avenue I wish to take to add yellow color to my lines. Germination takes too long (for me) and is not quite abundant enough. The few seedlings that I have produced have generally been discarded due to disease problems, and the yellow color coming through was not strong. Right now
I am hoping that Julia Child will be a better replacement. Easy Goin’ and Livin’ Easy have also produced a few good yellow seedlings for me, but the yellow tends to fade.
I recently moved from Minnesota to northern Wisconsin, but cold is cold. There is no question in my mind that my stratification times seem longer than for many of those on the forum. While I believe that the cooler temperatures are at least partially responsible for this, I also believe that using many of the more cold-tolerant plants in my hybridizing also contributes to a longer stratification time.

Yeah, it’s tough finding good yellows.
Bella Renaissance, also know as POULjill, is bred from:
Un-named seedling x Avigon.
Avigon is a floribunda bred in 1974 by Cants of Cochester. It is bred from Allgold x Zambra. The blooms are formal, double, 2.5 inches, medium yellow on well-spaced clusters. it says that the bush is “tallish”.
So, if my resources are correct, this bad boy (or girl ahem) is closely linked to the potent yellow Allgold.
‘Avignon’ has three doses of setigera through ‘Doubloons’. Interesting!
Is anyone working with R soulieana, which is a great-grandparent of Julia Child?
An old ROYT catalog says that Rs is intermittent flowering, and hardy in Maine.
I think Ralph Moore is dabbling with it.
He has a mini from it. Let me go find it…
Yeah, I found it…
The foliage isnt like most minis. The petals still have that typical pin-point tip, though.
Not my cup of tea
Oh, you gave me an idea. Earl Grey would be an awesome mauve rose name!
dave wolfe,
Regretfully, I’ve only done one cross using Rosa soulieana – it’s Rosa arvensis X souileana. I say regretfully, because I’ve lost my R. soulieana to Rose Rosette Disease; and the one I ordered last year, is definitely not the same rose at all. I wish I could remember where I got that first one.
As for being intermittent-flowering, mine only bloomed once a season. And I can only personally vouch for its hardiness to zone 6 – although I wouldn’t have been surprised at all, if it would have taken much colder temperatures.
Aside from Rose Rosette, it was very healthy. And it was an attractive tall shrub with smallish, “ghostly” gray foliage. I sure would like to try hybridizing with it some more.

Nice F1 Tom! At least you still have it to carry on with? I can see why it would be good to cross soulieana with a mini. Wow!
What are we going to do about Rosette Disease? We don’t see that here in CA so far that I know of.
Did I see a list of species that were resistant somewhere?
Allgold is one of the roses that seems like a good source of yellow. That is the main reason I thought it would be a good idea to use. HMF states that it is a Zone 5 rose and I have at least 1 report of its yellow color being fairly stable. There is also a comment on HMF stating that this is the first Yellow rose to overcome the ‘problems’ inherited from r. foetida. I am assuming that the ‘problems’ referred are disease problems. It has a bit of a fragrance as well.
Its an interesting rose. My first planned use for it is Allgold x Genn Dale / Glenn Dale x Allgold.
I’d skip Glenn Dale and go straight to Golden Glow.
I Golden Glow is next, but may end up first as my Golden Glow is much larger than my Genn Dale. I was hoping Genn Dale would have better disease resistance. I have heard a couple people mention that its ok but nothing great.
Goldbusch is one I had some luck with last season.
Julie, I agree with you on using ‘Julia Child’ extensively for breeding new yellows. It has superb plant habit and excellent flowering. In our climate it is very clean, but most roses do well here. I am glad to hear that it is clean in more challenging climates. It makes a very good pollen parent. It was crossed extensively onto an apparent blackspot resistant seedling of mine resulting from a cross of ‘Marmalade Skies’ X ‘Baby Love’. I will post later if anything interesting comes of that cross.
Dave, as I am sure that you have seen, many of Tom Carruth’s seedlings have R. soulieana in them, so they would be a good source of the bloodline. A couple of years ago, I got some OP R. soulieana seeds from Paul Barden. Of those, I selected a once blooming floriferous seedling that I have started using in my breeding program. Hopefully there will be something of interest that shows up this year.
