Re: Diploid vs Tetraploid - a crossroads

The end of the opening paragraph is a bit...questionable. Polyploidy for daylilies comes at a cost, significantly reduced seed set (often around 6 seed per tet cross but over 30 per dip cross) so advantageous reproduction possibly not. The flowers are generally more showy/larger/thicker with tets bu...

Diploid vs Tetraploid - a crossroads

I've been reading and gotten myself in a loop. I know there are people with far more scientific/technical understanding and familiarity here than I do so just looking for opinions/thoughts. Being in Australia, a generally favourable climate except those few weeks or summer with 40C+/100F+ temps. I'v...

Re: Canina Chromosome pairing

I am working with Lord Penzance, Lady Penzance will be coming in the next few months. Given a few comments on here i shouldn't expect germination until the second season so probably wont be til next year to see if any of the couple hundred Lord P seeds germinate I couldn't see an edit button but ju...

Re: Canina Chromosome pairing

That'll teach me to not look it up while on the train to work. Still it is a fertile triploid so should be less difficult to work with. They all trace back to Magnifica. On a slight tangent everything in my signature has some connection to one of the three. Given RADsweet I wouldnt be surprised if i...

Re: Canina Chromosome pairing

Not sure though it is easy to obtain a fertile tetraploid though, so the genes can be passed on to its offspring...

Re: early culling of species seedlings...

I'd imagine it'd depend on what species and what you were intending from the cross, I feel like usually there's an aim when using a species, I mean some species are obvious like R. glauca (thornless and foliage colour are likely the main superficial traits people are after from it). It'd also depend...

Re: Diploid x Higherploid or Higherploid x Diploid

Also need to consider that often both things, despite seemingly contradictory, could be true depending on the DNA sequences being looked at. I mean within a genus there's a lot of genetic overlap, look at humans and orangutans share ~97% of DNA....that's a lot of DNA that says we're the same and onl...

Re: Grow light recommendations

I can't recommend anything specifically but I use a lot of LEDS in various planted tanks...not exactly the same purpose but the same principles come up. If you want to minimise electricity usage while maximising wavelengths for photosynthesis you'll be looking for peaks between 420-450nm (blue) and ...

Re: reblooming botanical roses

And also I have one seedling from seeds of Applejack which is particular, because its leaves have a mix of fragrance of both parents. Lucky...and exciting. Possibly not exactly the same due to foliage fragrance (and being a different genus entirely) but I always think back to http://bulbnrose.x10.m...

Re: Diploid x Higherploid or Higherploid x Diploid

I've read heat often increase chances but I don't know how anecdotal that is. It could also just be the stress induced/survival mode thing, we (also in NSW) have had a lot of stupid hot days (40C+/104F+).

Re: Breeding plans for 2018

dgermeys; Lord and Lady Penzance have been around since 1894 and have no offspring to show, it might be a reason not to pursue this line of breeding. Possibly. I know Id be using different roses if the options where here. On the same token though, Greenmantle doesn't have any offspring listed eithe...

Re: Breeding plans for 2018

Hey Plazbo, Have you tried to breed with rosa rubiginosa or it's hybrids such as Lord and Lady Penzance? I have seed from them but only at the beginning of when germination happens for me. Its been mentioned on here that rubingnosa seeds take more than a year to germinate too, so first results may ...

Looking for others experience (R. Foetida)

When looking at pictures of R.Foetida they are always a deep yellow, even full bush pictures show a consistent deep yellow with all blooms. Is this just a case of Foetida having short lived blooms or do they just not fade? Comparing to many modern "no fade yellows" where blooms clearly fade as the b...

Re: Seedling, is it a sport?

Did you amend the soil, fertilize and water, repot, or otherwise do anything which, in addition to maturity, might make your plant happier? Yes, around a month to 6 weeks ago it moved up from a (6cm /~2.5inch) forestry tube, the previous two canes were half the size at the time. I just haven't seen...

Seedling, is it a sport?

I've not (knowingly) witnessed a sporting event so I'm left wondering if this may be a sport or if this is possibly just something that can happen with seedlings (because weird things often happen) that I've just not encountered before. The stem in the middle (growing from the base of an earlier ste...

Re: Newbie(ish) question

Thats essentially the plan.
I like the darker mauves but on a dark plant its less appealing to me. Would prefer to aim towards contrasts between leaves and flowers.
