Re: Germinating seeds

Yes and no. It depends a bit on class/species. I mean things closely related to species that rarely/never seen freezing temps arent likely to need stratification. Probably also location. My seeds often never seen spring. Im in Sydney Australia (very little chance of freezing, even then never really ...

Re: Is every rose seed completely unique?

I feel that we make the mistake on this forum of assuming that a particular rose species has a fixed set of characteristics. I respectfully disagree with Philip's above assertion that the differences are rarely noticable. I seek and cherish variations within a species. I would agree with this. Ive ...

Re: What is the easiest and hardest steps in rose breeding?

Hardest initially will be just letting seedlings go that have some problem or accepting the number of weak seedlings that'll die off from the modern classes (die off in species and older classes is much much much less for me). Letting seedlings and unproductive plants go is hard. Next would be figur...

Re: Finally a splotch!

On the blue topic, if you can track it down (it was bred in th USA) Man of Steel is distinctly grey/blue when the flowers bloom inside. Outside theres a pink/lavender hue and its paler, likely some reaction with sun/UV, inside its closer to Turn Blue and just very blue compared to the usual "blue" r...

Re: Finally a splotch!

I can also confirm it's dominant gene. Having raised many hundreds (or more) seedlings from the diploid Sweet Spot Calypso, many being selfed OP's (every flower turns into a hip, I sow everything...), there's instances where the blotch isn't inherited (indicating SSC is heterzygous for the gene/s) o...

Re: All A'Twitter x Yatkan

I just mentioned Stanwell because I recalled that post above from Ivan to some extent (that he got hips and seedlings from it). I figured given it's one of the commonly "sterile"/doesn't set hips in similar manner to Crested Moss and Robusta (which have set hips for me this season) that it's trigger...

Re: All A'Twitter x Yatkan

I don't know if it's the heat wave or the excessive amounts of pollen (ie 2 or 3 times a day for 5 days...seemed easier than looking for pollen that may or may not be found) but I have hip set on Crested Moss that I got this year. A lot of them seem to be phantom pregrancies (ie I can't imagine seed...

Re: So what's your magic number for days to harvest?

I use latex gloves when dealing with hips, between dermatitis reactions with the hairs, how glandular some of them are and staining potential from the hip flesh/juice.

Re: rose hips without inner hair?

I checked one of the Calocarpa hips. Very little hair, more like a very light fuzz inside, easy to scrape out. A lot of seeds though (30 - 40 range).

The very low hair is possible evidence toward Old Blush...will check that when possible.

Anyone growing Old Blush and being able to comment on hairs inside of fruits? Any other var. without hairs in fruits? Roses with any level of ploidy giving fruits but no or very little hairs might be acceptable to consider. Are there such roses already known? I grow Old Blush, but it'll be 2 or 3 m...

Re: rose hips without inner hair?

Old Blush x Scabrosa or vice versa. Does this make Calocarpa? Something of similar wide cross but likely sterile given Svejda's expirements. http://bulbnrose.x10.mx/Roses/breeding/SvejdaRugChin1974.html If going that path, Calocarpa, Sydney and Bonvista are probably worth looking at as they are at ...

OP seedling from Baby Faurax. Yellow base and reverse.

The only yellows nearby were Sunny Knock Out and Sweet Spot Calypso, Foetida, Golden Cheronese...likely pollen from further away as none of those seem appropiate at this point.

Re: Anyone breeding for fall color?

Glauca has the canina meiosis/unbalanced chromosomes issue (3+1). I've been attempting to use it as pollen on diploids as a source of low thorns. I don't think Ive been successful, others say its pollen is quite promiscuous so may be a difference in what we have here in Australia vs elsewhere (also ...

Re: Letting the bees do the work

There'd definitely be a significant factor in seed parent determining variability. I mean if the seed parent is from a wide cross you'd expect variability in offspring. I mean look at something like Calocarpa, a fertile result of a cross that typically results in sterile plants, while there may not ...

I do a fair bit of this, I collect and sow every seed regardless of intentional cross or not.
