Re: Hardwood cuttings and callusing

I've done it. Two weeks ago I took these cuttings. Treated them as per this article and I'm delighted to show that calluses are already forming on the cuttings without any special care.
I plan to pot them up this week. Any suggestions?

Re: new rose ‘Gaye Hammond’

[quote="david zlesak"]Thank you!! I love that like its tetraploid mom, 'Rise 'N Shine', it is throwing some dihaploids- infrequent eggs that develop into embryos that are unfertilized and have two sets of chromosomes. I raised a number of open pollinated seedlings of it this past spring and saved th...

Re: Leaflet rooting

Hi simonV, Forgive me, what plant zone do yo live in and what are your objectives in taking cuttings this way as opposed at just starting soft wood cuttings? This fall when I was putting my breeding stock to bed, I few branches broke off. I cut the branches up like yours in the photo and wrapped the...

Re: two different leaves on the one seedling???

Hi Karl K,
I've noticed this phenomenon on canes in local Arkansana wild roses here on the Canadian Prairies.
I've also seen it on my White Mountains hybrid. This plant is mostly thornless and then it'll throw a long cane
from the base with plenty of thorns.

Re: R. rugosa Alba x Dr Harry Upshall

Thanks Andre, I didn't put my WM up on a trellis this summer. I'll put a fence around WM to trap the snow. My WM seedling is very up right. I put some schneewerg pollen on it this spring thanks to Paul Olsen. The hips set was not very good, but I find even my seedling is sporadic from year to year w...

Re: R. rugosa Alba x Dr Harry Upshall

Andre, I love the above seedling White Mountains x Roseriae de l'hay. My hybridizing with WM is always spotty and based on erratic flowering of WM in pot. This year I'm trying different. I planted WM in the ground. I'm not certain it'll survive my prairie climate. Do you take your WM down from its t...

Re: What is your current choice of stratification medium?

Hi Roselynn,
I just finished statifying my rose seeds, I used I litre ziploc bags and just a 1/4 cup of pro-mix.
I add only one tablespoon on water to each bag.

Re: Species-Modern Crosses

Karl, these are some of the wild rosa Acicularis in my area. I'm hoping to spend a day there next spring documenting the variation in the flowers and stems and returning in the fall to reconcile the individual plants with the rose hips.

Re: Species-Modern Crosses

Karl, with the breeding work of Luther Burbank that you cited in mind. I know a place with many variants of rosa
Acicularis base on flower form. Should I be able to find naturally accruing double Flower hybrid seedlings?

Re: Species-Modern Crosses

Before I attempted rose hybridizing I read all I could find on rose breeding. My objectives were the same as now. Broaden the colour pallette of hardy roses available to gardeners in zone 3. One of my first tasks was to develop my own breeding lines. To that end I crossed species roses and hardy nea...

Re: Beginner Stratification Questions

Hi Roselynn, I follow the same principle, 2 months warm on top of the kitchen cupboards. From your photo, it looks like you are using lunch baggies. If I could suggest, you swap them out for thicker one litre size bads. The walls of those lunch bags are too thin and your seeds can dry out over time....

Re: May you help? [Genetics of Rose shape]

Hi Guys,
Here's a Kordesii hybrid that demonstrates that trait. I'm breeding for the David Austin-ish
look in yellow, but some times something like this shows up.
The buds took over a week to open. Our cooler weather maybe the cause.

Re: What roses are you banishing from breeding

Do rose seedlings sometimes outgrow or develop resistance to black spot?
I have a few 2014 seedlings that in 2015 came down with black spot. This year some are showing very little
sign of the disease.

RBaxter, With a Zone 8b/9a growing zone. I'm not sure what growing challenges you can face. Maybe mould , mildew and blackspot. These challenges are universal for all of us. Week to get the seedlings into the ground. I always promise myself I'll get it done in June, but it never happens that way. Ch...

Re: Yellow roses

Thanks Joe and David,
David, the chlorotic appearance of the top two roses may be related to the very cool damp spring we had in Manitoba.
Joe, how do you deal with the problem at the nursery?

Re: New yellow Spinosissima

Thanks Paul,
When Morden Sunrise first came out I made a number of crosses with it.
This is one of then from the seeds I have in Cold storage.
I should take a look at stored seeds to see what other gems I can find.
