Re: Use of Rosa blanda/woodsii in breeding

I'm hesitant to go down the rugosa pathway, mostly out of a prejudice born of iron chlorosis, poor blossom form, and delayed remontancy among rugosa seedlings. I know I should, but I don't know if I have the patience. In theory, the delayed remontancy could be bred out without straying too far, it'...

Re: Use of Rosa blanda/woodsii in breeding

It was just something that stood out while i was looking due to various people saying they are the same. The difference may disappear as the plants get larger but at this roughly inch height theres an obvious foliage colour difference. If blanda is very opppsed to alkalinity it may be the main contr...

Re: Use of Rosa blanda/woodsii in breeding

Just a random observation from seedlings grown from Sheffield seeds. It's easy to distinguish which is which without seeing the label, woodsii seedlings have much bluer foliage where blanda are mid green. Blanda seedlings also seem more prone to dying....which may or may not explain why there doesn'...

Re: Roses to consider for breeding?

It probably doesn't need saying but location and mileage may vary. Carefree Beauty frequently comes up in these sorts of things but is generally just gross for me in Australia. I know Warren (~700km/435miles inland from me) has said as much in the past and I believe has shovel pruned it and all seed...

Re: How to know how many plants I need for breeding?

As mentioned by others its going to vary by goals, location, available space, cost, etc.

The other variation is some roses produce 25+ seed a hip while others are lucky to produce 4.

Re: Is this color prediction chart accurate (or useful)?

I'd say the chart is somewhat useful if you look at the percentages over 20% as there's obviously some general trend there that's occurred over a bunch of different roses. You just have accept that unexpected results can and do happen. As the chart shows though, if you're looking to maximise your re...

Re: Is this color prediction chart accurate (or useful)?

Originally created by Steve McCulloch I believe. It was the results the creator researched. So there's some value in that but results are likely to vary due to using different cultivars. Would pay more attention to the higher numbers than the lower numbers as the trend of what to expect. I mean the ...

Re: Non-fading suggestions

There's a rose here in Australia called Fearless. Its starts neon orange and darkens to a burnt orange rather fades. Its not seed fertile for me but the pollen seems to have some viability. Its colour is great but the plant is questionable at best. Granted doesnt seem like its available outside of A...

Re: Why some crosses fail

I have to conclude that TB has really strong self-incompatibility, and maybe will only cross with diploid equivalents for some reason. I know others are probably less fond of the self-incompatibility thing but I like it a lot, it's reassuring with liliums for example to know the cross you made is e...

Re: Show and Tell?

There's also potentially golden touch (? aka Broadlands) which is a rugosa hybrid that apparently produces some fertile pollen. That may produce much more fertile children that can be breed amongst themeselves to see if the yellow can be strengthened.

Despite it's foliage being routinely wet all night (evening watering) and being the middle of "winter" it's remained completely ...

Re: Easy diploid seed parents

I haven't raised enough rugosa to gauge that possibility yet but do have a quite a few seedlings this season. I have seen similar less than a year blooming from rubiginosa (lord penzance) seedlings though so maybe i'll encounter it with rugosa too. Rugosa x woodsii/blanda hybrids are something I'll ...

I was already considering Old Blush so going all the way to beginning isn't a problem. I just didn't find anything on what to expect for pollination take, seeds per hip, germination rate.

Easy diploid seed parents

So there are numerous mentions of easy tetraploid seed parents like Gemini, Queen Elizabeth, Stainless Steel, etc scattered throughout the forums but when looking for diploid seed parents there's not really any mentions of anything that fits the bill. Marie Pavie is mentioned as producing around 8 s...

Re: Rosa sericea as a parent rose?

Given the several references to Cantabrigensis, maybe someone can confirm the following. Someone has posted several pictures on HMF and state the foilage is fragrant like rosa primula which is the first and only reference I can find. I do note that Sericea (var. Hookeri) is noted to be glandular (ag...
