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

David, I love the work that you have done in characterizing black spot resistance genes. It is a great service to all of us! Working somewhat "blind", in the mix of black spot races, since we only get mild cases in the spring and fall in our climate, I have been adding cleaner roses to the breeding ...

Re: purple stamens

Beautiful seedling Joseph.

Another rose that I used in the past with darker filaments was 'Geisha'. It was a nice rose and set hips too!

Re: Finally a splotch!

Hi Philip, no I haven't seen it yet, but good to know. Kordes pays great attention to disease resistance.

Will keep my eyes opened for 'See you in Purple'.

Thank you!

Re: Sproul's Striped Speculations

Hi Karl, I ended up making cuttings of the striped Lynn Anderson mutant and the striping was preserved. Ultimately since the mutation didn’t seem to produce viable pollen,nor did it set hips, I discarded it. This was several years ago. Incidentally I noticed another striped bloom on one of my Lynn A...

Re: Finally a splotch!

Karl, I am still learning each year new things about the Hulthemia blotch. It is definitely dominant, but I don't know if one copy of the gene(s), or 4 copies in a tetraploid makes any difference. There appear to be other rose genes that inhibit the expression of the blotch and/or modify how it is s...

Re: I'm confused: a diploid?

Hi mntlover, I agree with Kim that it is better to try whatever cross that you are interested in than trying to decide whether the cross is possible. There are many variables that can influence whether or not a cross "takes" and produces viable seeds. That being said, do you have a type of rose that...

Re: I'm new here, so I'd like to say hi!

Hi Josh, Welcome! You have done the right thing to read the RHA booklets. They have a lot of great info. I wonder if you met with the same group that I saw in early May. Prof. Shiwei leads a rose breeding team in Beijing. They have some very nice roses in the pipeline. They are a wonderful group. Wi...

Re: Rebloom

Reblooming in roses is definitely not simple and straight forward. I do not know the science behind it but from observation of seedling and species plants I have seen non-remontant seedlings coming from 2 fully remontant parents ('Gold Medal' seemed to produce a fair amount of non-reblooming seedlin...

Re: Pretty seedling out of Sweet Spot Calypso

Great blotch on that Sweet Spot seedling David! I cannot really breed for cold hardiness unless I get lucky! I have dreams of breeding success with Rosa acicularis, but doubt if the few crosses I made with it will produce anything this year. Maybe next year! Simon, I think you're right about E4Y. It...

Re: Some new Hulthemia Hybrids being developed

Nice work Warren! These are a challenge, but so much fun. Getting the blotch, blooming power and health all in the same plant continues to absorb my attention, but I really love working with them. Best wishes for a wonderful climber!

Re: Funny to see roots coming out of nodes of these cuttings

Hi David, that one looks very interesting! If you have enough later on, I would love to be on the list. You are expecting female fertility from this seedling? Right? Thank you!

Thank you Rob for reporting your experience with AL. So far I haven't seen any diseases on it. Right now I have a lot of downy, black spot and some other spotting disease in my yard. Powdery mildew is just getting started. I couldn't detect much fragrance on it, but love the color. How does it compa...

New Roses in Crosses This Year

I added 3 new roses to the hybridizing pot this year, and love what I'm seeing in all three of them: 'Shining Moment' (a Will Radler rose), 'Desdemona' (an Austin rose) and 'At Last' (from Horner). Does anyone else have experience with these? Which new roses have you decided to try this year?! Jim S...

Re: Splotch (ish)

Hi Judy, that's great! This pattern is characteristic of the halo markings. Have you tried 'Halo Sunrise'? The halo markings are different from the Hulthemia blotch. If you're interested in working with Hulthemias, I could send you cuttings of a good mini seed parent.

Re: Oddities for the season

Hi Paul, that micro lasted about 2 years, but since the blotch was very faint, I didn't try to breed with it and ultimately discarded it. I still enjoy the smaller minis - too bad that not many people do.
