Rose Hybridizers Association Forum

Hi Karl, Can you please explain in layman's terms how and why Warren Millington can get such great results using Canadian breed roses like Therese Bugnet,(as posted on FB). TB doesn't thrive, and hardly flowers or set hips for me here in the Manitoba. For a long time, I thought TB was sterile. Until...

Duan, I don't how long you have had your roses in the bigger pots. I started out using soil from my garden as a medium for roses in pots. I noticed over time that the potted roses became lethargic. Their flower production went down, and they succumbed after a few years. My farm agent told me I was a...

I agree with Joe's. The groundwater in my area in high in calcium. I never water with tap water,
I bring in snow in a garbage can, melt and filter it and use it on all of my indoor plants and rose seedlings.
In summer I have plastic totes under the downspouts to harvest rainwater.

Peter, You said it much better than I could. Rob, what I did since I started breeding roses 20 years ago this year. I started off with the Mordens like Adalade Hoodless and Morden Centennial. I crossed them every which way I could and planted out the seedlings. As Peter said, you need large numbers ...

Hi Rob, Instead of using Morden roses, how about trying one of the Explorer roses? I find they are more disease resistant than the Mordens. I still sometimes use Morden Blush if I acquire some species rose pollen. MB is very fertile and the seeds germinate easily. The best all-around Explorer rose f...

Hi Joe,
Have any of these crosses yield any thornless seedlings?
How long did you have to wait to get blooms on these hybrid seedlings?

Thanks for your kind words Andre. R. Acicularis was collected from the wild here in MB. I was surprised at the variations of the flower and hip shapes of this rose. I hope to return to this site and document some of there variations. Karl King suggested that there maybe double specimens in wild spec...

Hi Andre, I've worked with Fedtschenkoana since 2006. I crossed it with Morden Blush and R. Acicularis.
Take a look at my thread " Taming the Wild Ones"

I"ve always wonder about this too. I tend to use the cultivated rose as the seed parent. The seed set is often higher and germination more predictable. One thing I am having trouble with, is getting viable offspring from (wild sp. x Garden Rose) x Garden Rose. I wonder if environmental conditions, i...

I have found over the years of using Hazeldean to create yellow non-fading yellow roses. Hazeldean does not pass on its yellow colour to its offspring readily. Hazeldean seedling have healthy foliage, but many of the seedlings also produce deformed vegetative buds that do not open in cool, cloudy we...

Hi Warren, I've been working with Hazeldean for about 15 years. Progress is very slow with just one hundred days from last frost in sping to the first frost in fall. Like some of the rose breeders in this cold climate, I went back and read not just about Percy Wright roses, but some of the other Mid...

Lack of winter hardiness is one of the biggest problem I've face in my quest. Since I'm trying to achieve a rose with a prominent white centre, I thought a starting point with a rose without many petals would be a good idea. Roses like, Gizmo, Hoot Owl, Space Odyssey. Joe, your pics. demonstrate the...

Thanks everyone for your input.
I've been working on this for almost 20 years with some progress, but in all of my seedlings
the outer edge was not vibrant enough, more like a deep pink or bled into the white centre.
Maybe these goals are unattainable.
Chuckp

Trying to develop some roses with deep red outer petals with clear white centres.
This seedling has Betty Boop as a parent.
Any suggestions?
Chuckp

I'm still hoping to acquire EGS1 and use it with some of my own seedlings. Does EGS1 set hips, and if so, does it have
good fertility when employed both ways?
Chuckp

Looking good warren.
How many seeds are you expecting to harvest the year.
Do you extract the seeds by hand one hip at a time or do you use another method like the blender?
Do you divide and hold back a portion of each cross against a disaster?
Chuckp

Very nice Warren,
You seem to have the optimal climate for coaxing the most out of your roses.
Manitoba's overnight wind-chill temperature dipped to -44 deg. Celsius.
Not a place for the faint hearted. Best of the New Year to all.
Chuckp

Hi Warren,
Has the Fru Dagmar Hastrup (T) Type 1 x R. tunquinensis that was in bud bloom yet? Can you show us the photos?
Thanks you, chuckp.

Hi Warren, my hat off to you, you are making a star of a litte unknown rose from the Canadian Praries.Bravo.

I came across this thread and have a question. Most backyard rose breeders like myself do not have a dedicated refrigerator for the 3 month cold stratification. Ripening fruits and vegetables give off ethylene. What effects(negative or positive) does putting rose seeds in a home refrigerator with fr...
