Re: Pollen from Canary Bird

Similar experience to Kim here in Sydney Australia. Golden Cheronese generally has 3 flushes a year for me, the latter two aren't as big as the first but still quite a lot of flowers. Glauca often twice. Other once blooming species are only a year or two so they may start "reblooming" as they get mo...

Re: Pollen from Canary Bird

Sadly can't help there.

Possibly go the other way and have someone in a warmer climate pollinate with hardy pollen and send you the seed...maybe something from that will survive for you?

Re: The cross that's worked best for me

It's a known good female, so I'll try a plant of it. I know a lot of it's seedlings are with it as a seed parent but it's been a case of big fleshy hips and few seed for me. Is that not the case with others? Not awful by any means, but a bit more work than with a lot of other seed parents to get a ...

Re: Unique black spot resistance gene from 'George Vancouver' is better characterized

Thankfully these genes are dominant and all we need is one copy of an allele of a gene to confer resistance. ....... This gene does not provide resistance to all races of black spot, but 9 of the 13 we have in the collection. This gene in combination with other genes would increasing provide resist...

Re: Strat Question

I have germination now from seed harvested a month or so ago. Night time temps are starting to dip below 59f this last week and a bit, theres some rain most days (possibly washing away any inhibitors). Hulthemia hybrids, rugosa hybrids, chinas, multiflora/polyantha, moderns, portlands, sweet briars,...

Re: Unique black spot resistance gene from 'George Vancouver' is better characterized

You can find some via google "rose rdrX resistance" Rdr1 is often mentioned coming from multiflora Rdr2 took me down a rabbit hole but I'm sure something specific is said but with the linkage may or may not be a similar list to Rdr1. Something to look in to when I'm not on a train to work. With Brit...

Re: Apples and Oranges

No, I meant the Zary HT, it being a descendant of orangeade (a couple generations back)...part of that probably not useful info disclaimer. Pulling rosacyanins down to triploid then diploid is something I've been attempting. Unsure of success/failure. None of the seedlings showed any obvious sign of...

Re: maximum germination temperature

Folk in TX, AZ, CA have it even hotter longer but produce seeds that germinate. Maybe not as well, maybe not for all types, for sure I don't know. Perhaps some of the RHA members from those states could comment. Different country but similar 100F+ temps for long periods of time. No issue with polys...

Not the same but similar lines, I did Gemini x Blue Moon....just deep pinks/cool toned reds and a lot of things with bad roots that died...that probably isnt helpful info.

Re: Apples and Oranges

To be fair, those are dark purples compared to the lavenders that appear to be the topic by Le Grice. Not that the mechanisms don't have an overlap, just that it's understandable how he'd ignore them given the very different visible colour.

Re: I'm confused: a diploid?

I have two seedlings with juvenile remontancy already, one from Therese Bugnet and one from Martin Frobisher. I was hoping to have more to work with, maybe crossing each of these together. Possibly. Depends on if the cause of the juvenile remontancy is the same/similar....although it's more a case ...

Re: Coutts #4

Radler's hybrids meet many of the criteria but a few colors seem to dominate, yellows are rather weak intensity or staying power. and fertility for me is never what you'd call impressive. So I'm trying to overcome all that. Very much agreed, even then when they germinate it's often a miss. eg Sunny...

Re: Germination of crosses I'm excited about

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.

Re: purple stamens

Kim, are there hulthemias with purple anthers as well? The very few I can think of off-hand seem to have yellow anthers, though with colored filaments. They can be, but Im seeing more red/dark red. I've raised a lot of seedlings from Sweet Spot Calypso (a lot of health issues though) and it varies ...

Re: Coutts #4

Stanwell Perpetual indicates that rebloom and long spiny canes can happen together...just maybe not in the conventional way...granted the question is hypothetical. Given most of the hulthemia on the market (at least here, mileage may vary) are physically so removed from the species apart from the bl...

Do you know the roses 'Little Pet' and 'Félicité-Perpétue'? The last one is a climber, the first one is a mutation from it and and a mini rose, Félicité-Perpétue is only blooming once, while "Little Pet" is flowering all the time. Most of the dwarf roses flower continuously... related observation O...

Re: Grandiflora or Hybr. Floribunda?

The other part of it is rose shows/societies/trials, they'd be playing some part in keeping classifications going via awards. Here in Australia, some nurseries don't even bother with the Floribunda/Hybrid Tea distinction. eg Wagners Some of the early "grandiflora" can be monsters though, June Bride,...

Re: Petite Knock Out Rose - AVOID

These days, DNA techniques are so cheap that you don't really need a specific single gene to tag. Just compare a bunch of markers on several chromosomes that represent the haplotype (particular arrangement of different alleles in this cultivar). Works exactly like the DNA database that the govt use...

Re: Petite Knock Out Rose - AVOID

Given the assumption the tracer gene (if it exists) is from the unknown grandparent, isnt it statistically likely the gene will fail to pass on?
