Re: Unusual Species to Use?

R. xanthina has perhaps my favorite name. As a kid I read a series of fantasy books by Piers Anthony set in a fictional country named "Xanth." Alas, my seedlings of R. xanthina died back too far each winter here in Zone 3b to ever get more than a smattering of blossoms, so I removed them. I think ev...

Re: Rose seed germination - new M.S. thesis

I hate to be that guy, but there's a common grammatical error in the very first sentence! Kind of curious how they let that through.

Re: Seedling/genetics question

Another rose to look at is "Ruglauca." I got some fertility out of that, I think. Not full rugosa fertility. I may have posted seedling pics on the forum here if you search it for that. (use google: "site:rosebreeders.org ruglauca"). The first hurdle to jump for your seedling will be if it has good ...

Re: Yellow Species Roses?

to elaborate on Kim's paragraph above, when you put species pollen onto a modern reblooming rose often selecting successful crosses is as simple as finding the seedlings that don't bloom their first season. Technically if the modern rose had been self-pollinated then all of the seedlings would have ...

There really is only one way to find out if their dwarf stature is genetic or environmental...I hope you collected a few of the hips. :)

Re: 0% germination, what am I doing wrong

Seven weeks is not a super long time....any way to put the germination trays back in the fridge? A lot will depend on the seeds, too. I often get zero percent from polyantha seeds, for some reason. If you can find a seed and cut it open with a fingernail clipper (sacrificing it as you'll probably da...

Re: Need Advice - I'm Just Starting Out

Hi jwdykes, 2. Don't start out worrying about polyploids and diploids. There are some really good triploid roses that come from crossing diploids with tetraploids. Ploidy is relevant to breeding, and some problems can arise crossing ploidy, but when you're getting started I'd say ignore ploidy and h...

Re: Wasagaming seeds

A drop or two of dish soap in the water may cause more to sink so you can get a better idea of potential viability.

You could also consider hacking a few open with a fingernail clipper to see if the embryo inside is withered or plump.

Re: 2020 Seed Exchange

I'm interested in The Fairy and Hansa, partly because of their diploid status which makes them likely to have not self-pollinated. Therefore some potential for interesting and varied OP seedlings?

Re: Splash and Dash equals Bad Technique?

Good questions here and info from Don.

I've noticed before that certain pollens had a tendency of producing smaller than norma...

Re: Sweet Spirit

Duane, I kind of took a year off from intensive pollination, and as such only pollinated about two hips on Sweet Spirit, both with pollen from CASNIT1, my cross of Canadian Shield and R. nitida. However, the enormous size of those hips speaks well to the fertility of Sweet Spirit. I would certainly ...

This almost could have been a reply in the recent thread asking about hips generating excitement. But posting as new thread to avoid thread-jacking. I’m kind of excited about Sweet Spirit. I have two plants that I keep in pots and store inside for the winter. It is a Double KO descendant, which migh...

Having worked so hard to incorporate R. virginiana and R. carolina into my seedlings, I'm probably screwed in terms of creating a rose that's healthy nationwide.

I don't seem to have downy mildew here, although I'm not sure I know what it looks like. I still have AATYAK, now growing in a pot in the greenhouse. I love the foliage. I actually have a few seedlings of it this year, but didn't make the effort to pollinate with it this year. We'll see if those see...

Re: Problem with rabbits

Liquid Fence might work. It is a spray that you spray right on the roses. We use it around here, mostly for deer.
