Re: Open Pollinated seeds

Kim is 100%. For example, selections from any given species can have a range of black spot resistance(s). Selecting out of open pollinations could result in being able to select from the useful extreme of the bell curve. More practically, many species rust and get downy REALLY BAD. Selections from O...

Re: Hesperhodos experiment

I saw your pics on HMF this morning. My first thought: "omg its so fuzzzzzzzy~" lol I think one of the genetic potentials of roses like this, as well as a few others, is that their internodes are very dense, even compared to Rosa wichurana, which could translate well into moderns. Another genetic po...

Re: Germinating Alba seeds...question...

Hi, David, When I did a lot of caninas, I used our natural winter here, which hovers between 33-40F, is dark, and very wet. So an outdoor temperate rainforest winter will do the trick. Only 1-2 days per winter will there be light snow, and about 1-2 weeks total have frost w/no moisture in the air. T...

Re: Size of seeds?

[quote=Gernerhahn post_id=72266 time=1603809222 user_id=2303] Has anyone ever done any test on seed size? In some crosses the seeds differ very much in size. I always do a float test, and still I am left seed that are half, or a third, of the size of the other seeds from the same cross. I always pla...

If they are like canina, which they directly descend from, they should be quite easy to germinate.

Re: Color of hips Abraham Darby

Many patents will state hips and other odd traits, so be sure to check them. They're available to view for free through our government site. The data may be skewed to location of testing, but its likely to be in the ballpark if they state it at all.

Re: Color of hips Abraham Darby

Brite Eyes, its kiddo, turns bright orange for me. When I used to own Jude the Obscure, another kiddo, they always stayed bright green for me. Aloha, its parent, can get slightly tinged hips. Its other parent, Yellow Cushion, has a patent that state they can turn "apricot". I think the safest bet wo...

Re: Genetic determinism of prickles in rose

Pesky recessives :]

Well, whatever the case, Bonica and Summer Wind are good at either reducing or eliminating prickles. I have some linebred Dortmund types bred with Bonica. Zero prickles -- 7 years old now. One can see Meilland has also used Bonica in climbers for this exact reason.

Re: Seeds and RRV

It's not a pipe dream. Members like David work very hard at researching it. Anyway, the moral for members is that if a wholesaler or private nursery reads on any of these medias that a breeder has touched this stuff, they simply will give a hard no to working with the breeder. I don't want people to...

Hi, Stefan, I disagree, and this is why: RRD can wipe out an entire wholesale nursery and their reputation. Black spot cannot. RRD can force wholesalers to never consider one of us as viable, as well. Similar can be said about mom and pop rose businesses that drive our niche, personalized markets. I...

I'd nuke it to high heaven :] But that's me.

Its the #1 thing that threatens rose culture as we know it, in strong competition with the ARS doing a poor job at attracting millennials, and now zoomers, to our culture.

Re: Zaiger work flow

Due to living in the PNW and next to temperate rainforest, I have always had to time everything between the rains, but also the immense cool humidity during the nights during the May-June pollination season. In fact, I have had to extend pollinations into July frequently to accommodate for el nino/l...

Re: Splash and Dash equals Bad Technique?

I use splash and dash for new roses, seedlings I want to test. It's all about the metrics, and you have to go go go during pollination season. I take my time and often repeat the day after on important mother plants that will give me a lot of what I want or a plant that I would be okay with one mira...

Re: Sweet Spirit

Sweet Spirit may germinate better than some HTs since its descended from Peace no less than 7 times, as well as a descendent of Playboy on possibly more than one occasion. Many HTs have abysmal seed count and germination rate despite massive hips. That's one reason you will often seen a lot of roses...

Re: New black spot article out today

It further illustrates than one should not cull a really nice seedling just because it is prone to one type of BS on a minimal level. In the prior study, Sunsprite was listed as novel. Mine has retained all of its foliage since March, and has only now shown a few spots of BS on the very lowest layer...

Re: Sweet Spirit

Bloom size alone gives a higher chance SS is tetraploid, given how small the triploid DKO blooms are. Also, DKO is not as healthy as KO, but it has better behaved blooms and plant architecture. KO, in my experience, produces better colors. DKO and its mutations tend to breed washed out bicolors with...
