Rose Hybridizers Association Forum

I'm excited Dave Schulte has picked up the series and has enough 'Sven' ready to sell. Hopefully the other 3 will be ready to add to their offerings soon. I had a great visit with him and his wife about their efforts to make them more widely available again. Dave has a strong passion for a wide rang...

Hi Rob,

Yes, but I cover all my pots with construction blankets to get them through the winter.

What an interesting topic. Like Joe, I've noticed the more seed in a hip the more energy seems to be diverted there and the faster the ripening. Also, general hybrid vigor may be involved. In a past Gudin et al. paper they looked at pollinations done at different temperatures and besides impact of t...

I was able to purchase the yellow one and red one (I think the red one is from Meilland) and have them in pots still. I actually got them last summer and have to build new beds. They seem healthy and very nice so far. There isn't much for op hips on them.

The pollen of 'Chinook Sunrise' is relatively fertile it seems. I used it on a number of females and the seed set is pretty good. When I tried to use it as a female parent there weren't any hips that formed or any op hips either. Someday I'll try to count its chromosomes to see if it may be triploid...

We were looking for Rosa x kordesii for a black spot research study to understand if it may be the source/share the same black spot resistance gene that is in many of the Explorer series of roses. It was very hard to find R. x kordesii in the US. A friend from CA was very kind and shared a couple cu...

Hi Chuck! I'm not sure of its story. I saw it for sale online through J&P a couple years ago and was excited to try it because it is yellow. It grows like a mini and I forgot if they sold it as a mini or shrub. There was no code or variety name in small print associated with the marketing or tag. I'...

I haven't seen 'Twinkling Lights' for sale in a year or so, but Jackson and Perkins was selling it. The yellow color is very rich and doesn't seem to fade much at all. Unfortunately, it doesn't set any hips. I tried some of its pollen and have to check to see if any hips are forming using it.

In the Twin Cities area there is a special school fundraiser plant sale Mother's Day weekend that is huge now. They bring in a lot of plant material from Jeffries in Canada and many other nurseries too. I got an 'Olds College' last year and 'Chinook Sunrise' this year. I love the double warm colored...

That rose of your friend's Kim is very beautiful!

Your seedling is beautiful!! I love the dense habit and richly colored blooms.

The variegated seedlings from this spring posted above for the most part don't look too healthy. The variegation seems to be less pronounced than before and lead to the leaves being smaller and kind of mottled and off color. I shared some for virus testing and it'll be interesting if something is fo...

Thanks everyone! For the water in the pollen germination assays I've just used RO or distilled water in the lab. That is a good question how much city water with chlorine or water with various minerals would impact the results.

I was visiting with a rhododendron breeding friend last week and she says she uses honey on stigmas when she emasculates and doesn't want to wait a day or so for the natural secretions to build so she can pollinate right away more effectively. I saw her make some pollinations. She uses raw unfiltere...

Thank you for posting this Henry! A challenge is that sometimes the symptoms look a bit different from cultivar to cultivar, but it is great to have as many pictures of the range of symptoms for each virus as possible to have a good starting point. For Rose Yellow Mosiac Virus, for instance, not all...

I think I read Burling has obtained stock from FPS, if available, for the cultivars she sells. I forgot the details now, but that is why I think I ordered 'Crimson Glory' from her years back.

Thank you Henry for posting this!! I appreciate that you are quick at finding rose literature and sharing it with others on the forum. It is nice to have strong connections with trade magazines to have articles like this each year to get our word out about the program and the new winners. It is nice...

It is a bit slower growing and weaker and it is a single soft pink.

It is great that the PowerPoints are listed. I especially love being able to see the roses that have and have not shown symptoms yet of RRD in the Oklahoma and other trials and learning about some of the techniques being developed and are available for RRD detection.

That sounds really cool Joe!!! Thank you for the great idea!!! I have one A&B rose in a pot and should try that. It is usually just a good male. That is great higher temperatures may help with overcoming more than just some of the typical self-incompatibility limitations.
