This rose is fantastic! I would consider commercial release. Hopefully it is at least partly fertile- we all need more color in rugosas, and the orange bloch at the base could be a 3rd source of the halo/blotch pattern.

OK As I can't edit the description table for that rose (don't know why), I'll post some infos here, as its really important to know more on that crossing.

Its my own crossing from May 2007 where a few dozen seedlings derived with one, presented here, that already flowered this year in May 2010.

There is a thread for this crossing / breeding line on the RHA Forum site:

http://www.rosehybridizers.org/forum/message.php?topid=30065

The flower is of a salmon colouring with a small orange base at the petals!
The reverse of the petals is more of light pink, the upper side more of light yellow ... .

For me it was interesting to see, that the yellow colour of Golden Chersonese is not completely inherited in the descendents.
I supposed this, as there seem to be different (at least two) traits of yellow, - one light yellow and one deep yellow.
Sometimes they are mixed - as in Golden Chersonese, I supposed (see also answer to Robert below its the thematic of the maternal inheritance of traits in some few examples that might play a role here ... .)

The deep yellow trait seems to be inherited only via maternal pathways ... if one takes deep yellow influenced roses as mother plants, - and not as pollen parents like here (so for deep yellows its like a chromoplast inheritance, not a classic mendelian inheritance).

It will be also interesting to see how the plant further develops, still its a pretty dense bush (only once flowering in spring).
Its not blackspot resistant, but mildew resistant. ...

Arno,

Did this one set hips for you? I'd love to see some updated whole-plant photos of it if you have any.

Congratulations.

Wonderful looking first blossom and amazing potential parent. I think getting any kind of yellow color in a first generation rugosa cross very encouraging.

Hi Robert!

Thank you, - its also really a good testing for inheritance of the yellow traits - as there seem to be at least two traits for yellow (that seem to be mixed in Golden Chersonese), a light yellow trait that can be transferred via pollen (as in Rosa hugonis or Rosa xanthina) - as one can see here!
And a deep yellow trait (as in Rosa ecae) that is maybe only inherited maternaly - via the mother plant.

For me it was a testing for these "truths of traits". That was the reason for me why I did this crossing. If the syblings will flower one knows more. So far it seems that I was right.

I took the white from rugosa alba as a sort of "canvas" for the yellow traits - and the outcome is nearly what I have expected.
Only the salmon was a bit surprising to me ... .

Grx!
Arno
