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: R. carolina video

Pretty exciting for me to see those as I have some seedlings from the species coming along. I love the cooler-colored matte foliage and bright hips. I got woodsii seed from sheffields seed. Sown March (autumn/fall here) and they are around 2 foot tall now, most of that growth being in the last 3 mo...

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.

Re: rose hips without inner hair?

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 ...

Re: Use of Rosa blanda/woodsii in breeding

Just a few months on and seed grown woodsii are doing far better, confident multiple will reach maturity, one of them in particular is very vigorous. Still very blue foliage (which is funny given the bare root fedt i got is quite yellow...possibly drought/heat related) The seed grown blanda though a...

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 ...

Re: Letting the bees do the work

I do a fair bit of this, I collect and sow every seed regardless of intentional cross or not. Knowing that a lot of seedlings will die for one reason or another (often lack of care in the extreme heat and drought conditions...sometimes I just don't water often enough), it's currently worth my time t...

Re: All A'Twitter x Yatkan

It's something that I'm doing myself. Even though the eventual plan is to be mostly diploid there's a lot of traits from higher ploidies that I'm hoping to move down to diploid which are often attached to once bloomers or older classes without juvenile bloom. Making triploids that are once blooming ...

Re: All A'Twitter x Yatkan

If you're in zone 5 that should make your work easier, because the once-blooming seedlings in the first generation of a species-modern cross should be able to have enough live wood to bloom. Then you cross the best of them with another rebloomer and select for juvenile bloom in that F2 generation. ...

Re: Questions about seedlings traits

The "secret" is probably moisture, and cooler temps. I don't disagree with Baby Faurux, its often one of the first to indicate i need to water more often., no drought tolerance to it. Blue for you seems straight up temperature related though, it crisps without much effort where most things are fine...

Also interesting that you used centifolia. Could you expound on why that was your choice, as I've read a lot about sterility issues, and apparently that isn't the case with the pollen you used. Any thoughts? Thats more a mechanical failure in centifolia, in most the majority of sexual parts are con...

Re: Questions about seedlings traits

Do we know if the fragrance in leaves is passed on through the mother or father? I read a little mentioned here on fragrance but either didn't read that, didn't understand it, or forgot. It depends on the source. Most of the more common sourves for apple scented foilage are closely related to R.rub...
