Germination of crosses I'm excited about

some recent germination of crosses that I'm excited about.

Quadra x Cape Diamond
Quadra x Prairie Snowdrift
Qaudra x Frontenac
Prairie Joy x Frontenac
Screaming Neon x Cape Diamond
All the Rage x Morning Magic
Lemon Fizz x Frontenac
Morning Magic x (11Z29 x OP)

There's some good hardiness and disease resistance genes mixed in there.

Congratulations, Rob! Now I'm all excited and have to go to HelpMeFind to look all of these up so I can speculate about who they'll take after. Yours is the first batch I've heard of this season. Makes me want to have a look at my OP practice seeds in the fridge. Can we see photos of these plants as they come along? - Brian.

Thank you Brian. I'm hoping that others will post some of their crosses as germination starts. I sure hope some of mine will be good enough to post pictures of!

When you go to HMF to look up some of these parents look at Quadra. Besides being very cold hardy and disease resistant, Quarda has somewhat of an "English Rose" bloom type which I like. I learned that Quadra and Frontenac come from the same cross: B08 (Svejda) × Félix Leclerc. I hope you get germination soon.

I generally don't talk about germinations, waiting to see flowers. I had germination about a month ago and the first flowers are popping up. These were seeds put into cold stratification back in August. Most interesting will be the considerable number with Above and Beyond as the pollen donor and one of at least a dozem different CV as the flower getting pollinated. I used that pollen until it ran out on some un-named seedlings such as New Dawn x a yellow miniature (NDymin) that grows fairly tall and reblooms if hips are kept off, or even when left on (as they ripen). Also Brite-Eyes, Music Box, High voltage that I got from J. Bergeson some years back. Several hundred seeds giving maybe 100 seedlings so far with very few showing an intention to bloom early.

Best flower of the day, a double light pink on Silver Moon pollinated by the NDymin pollen (which I had never tried before on anything). Some single pinks out of the same cross. None of which I need.

This week I've had seeds from Sept sprouting. Overall total all dates so far, around 350 in 5 flats of 6-paks with usually 2 seeds per cell. Final total will likely reach 600 seedlings, but not a lot of repeat bloomers using A & B, my similar #1100, Austrian Copper just as an expt on the roses from Joe B., anything on Silver Moon.

Good crosses, Rob! Thanks for breeding for cold hardiness. Why haven't I grown Quadra?

Larry, the seedlings of A & B that have juvenile & repeat bloom are precious indeed. I know they do occur, as I have one Henry Hudson x A&B and two All the Rage x A & B that repeat. As David has mentioned, there might be some preferential pairing that goes on and greatly reduces the percentage of repeat blooming seedlings. That same preferential pairing, however, will mean that the non-blooming seedlings will be Rrrr for the recessive repeat bloom gene and will pass on 50% rebloomers when crossed again with a repeater.

So, there is hope. I do have a couple flowers opening but I worry they are selfs of the female in the cross. Most of the A & B so far have red young foliage and no sign of a flower bud.

I thought that A & B seeds sprouted fairly quickly. But some Lynnie seeds from Kim R. which I stratified Nov 2 just popped up. That about 90 days, in the cold. No warm spell yet. A matching batch came out with fewer sprouts but now they are getting a month warm, so they can then do a 3 mo cold, 1 mo warm cycle like von Abrams and Hand did back in the early 1950s. I tried that pattern last year or 2 for some R. canina and R pomifera seeds had got good results through3 cycles

If I come up with something promising I'm hoping you would have room to test for your zone. I've narrowed my breeding efforts and very hardy, disease resistant and floriferous bloom are my main focus. I also have a couple other lesser avenues of interest that I'm working on.

Quadra, you should have this one! Nice color, beautiful form, very disease resistant and is very fertile...

Rob, thank you for your recommendation of Quadra. I looked it up on HMF and am really impressed with it. It seems to have everything. I had never heard of it before. I can hardly wait to add it to my stable. When I get a stable. So, how do your first flowers look??? It has been snowing in my town for four months and I would be happy to see Anything.

It will be a few weeks before I see flowers. I have tiny buds on my Louise Estes x Frontenac seedlings.

A few more germinations that might be interesting:

Nyveldt's White x Oso Easy Mango Salsa (both diploids)
Royal Edward x (Clare Grammerstorf x Prairie Peace)
Neon Red x Cape Diamond

I have buds on Prairie Joy x Prairie Snowdrift and on Louise Estes x Frontenac seedlings.

I've noticed germination of hugonis, xanthina and fedt in trays from last year...the diploid yellows really are a 2nd season germinate. A little surprising given the complete lack of water and significant heat wave events. I wonder if ecae will start germinating.
Anyone able to send rosa californica (op) seeds to me in Australia?

Thanks for the recommendation of Quadra! I was able to pick it up locally.
