Grand Siecle

I know nothing about this pink <yawn> rose, but it is purported to have an average diameter of 8 inches, and excellent disease resistance. I would assume its rebloom might be rated as "meh" in view of the effort that probably goes into each blossom. I find no mention of it on this forum, a...

Re: Strategies_for_the_development_of_unique_flower_forms_in

Okay. So, to be clear, you are talking "selection" and not "heritability."

Re: Strategies_for_the_development_of_unique_flower_forms_in

Does gain-of-function really correlate with dominance, or do you mean to say that gain-of-function mutations, when they occur, are often passed on to future generation whereas the others are less likely to be reflected in future generations? For the most part, the generalization about mutations rare...

Re: Calcium Nitrate protocol, again...

Thanks, Larry! Apologies for any confusion I caused in my description. I think I heard that ammonia can be toxic to seedlings, so I'm glad to hear that it isn't that!

Re: EGS1 - growing & breeding experience

Interestingly, on HMF, Suzanne itself is listed as having very good disease resistance. I'm surprised to learn its offspring don't, Joe. But I have hypothesized in the past that as different roses have differing disease avoidance mechanisms, it might be dependent on the class she is crossed with whe...

Re: Origins of Yellow John Davies

I still kinda like the idea of the "Terry's Prairie..." series. ;-) Glad to hear that it is being trialed, and that you will get the credit for your work, Terry. It's an attractive bloom, and while I'm a southerner, it seems like a good addition to the palette of hardy roses. I am sure the...

Re: Calcium Nitrate protocol, again...

BTW, I unfortunately won't be able to provide any meaningful feedback on success of this solution as 1) seeds are very old and may lack viability, 2) the limited quantity of any cultivar is statistically meaningless, and 3) I will have no control whereby I could compare results, but for anyone who c...

Re: Calcium Nitrate protocol, again...

Thank you, Larry! Admittedly, I got lost a little bit with your numbers, but you did jump start a few of the old neurons. (I didn't, however, grasp the accounting for the Ca in the math.) I tried calculating this again and I got *close* to the same solution: Striving for: 10 mM Ca(NO3)2 = 20 mM NO3 ...

Re: Calcium Nitrate protocol, again...

BTW, I assume it is easier to calculate going metric, which is fine by me. I certainly won't be needing more than a liter of the stuff in view of my paltry harvest.

Calcium Nitrate protocol, again...

Sorry to be bugging everyone about a protocol that I think most seem to have mastered. I have yet to attempt it, but have some valuable seeds I would like to try to resuscitate and germinate after more than a year in the fridge... Like, as in, two years... Having called and confirmed they stock such...

Re: 2017 Virginiana Hybrids

Very fun blossom on that last one, Warren, and some very nice seedlings all around. Is the last one a mature form, or one of the earlier blossoms? You have some very impressive seedlings to show for your work, and as someone with limited resources (time and land) I am curious, if you don't mind my a...

Re: Origins of Yellow John Davies

Saw a recent post mentioning John Davies, and (as a southerner not familiar with the hardier Canadian cultivars) wondered what (if anything) ever came of, what I will call, "Terry's Prairie Gold" for lack of a better name. Don't see much on HMF under Terry Roszko's name. I am troubled to t...

Re: R.glauca help?

Getting slightly off-topic... I understand that R. glauca, as a caninae member, favors passing on predominantly its own genes as a seed parent. My interest in the plant would involve maintaining many of glauca's attributes -- notably foliar. My question: in a theoretical cross of (R.glauca x diploid...

Re: white out/white KO

Thanks. I don't know why it didn't occur to me to use the Google "site:*" search tool. (I used to use that frequently) I just expected some of the same protocol to work on this site's own search tools.

Re: Old seeds...

Thank you both for your insights. I have never had any success with old, dried seeds in the past. Don, thanks for the water temperature info -- I probably would have tried with tepid water. I've also never attempted any embryo extraction, but might do a little practice run on the White Out hips I co...

Old seeds...

Apologies -- I know this has been addressed time and time again, but cannot find info... I have seeds that are 2 years old, having remained in the hips (now completely desiccated, or course) and in the fridge for *most* of this time with only a paper envelope for protection... These include well ove...

Re: white out/white KO

Thanks, Karl. I assumed that would work and tried as much. Still got posts with either/or "white" and "out" despite putting quotes around the entirety as I would for Google. I'm using Chrome, but can't imagine that would be the problem. I'm recreating the same results right now.

Re: Yellow roses

Thanks for that info, Larry. I noticed it had Baby Love in its pedigree too, and several years ago everyone was raving about Baby Love lineages. I think the consensus turned to one of, great vertical resistance, not so much on the horizontal, for BL. I'm now noticing that on HMF, SW only gets a &quo...

Re: Yellow roses

Chuck, I know some breeders on this forum were using, and recommending, both Lemon Fizz and Sunny Sky as good yellow Kordes parents. I think a lot of breeders aren't really revealing parentage to the extent they used to, and that might account for the lack of parents showing up. On the subject of so...

Re: Early germinations (lots of it)

You make a point there, Kim, and I can already see my own child pulling that one... ...Come to think of it, I probably have made similar jokes to my own mother. The one I *do* recall involves her "Dear Lord, if I ever get to be *that* bad off, just shoot me" comment that has occasionally e...
