It is great that the papers associated with talks and posters from the VII International Symposium on Rose Research and Cultivation in Angers France in 2017 just came out!! Here is a link to the articles in the volume. Even though many of us may not have free access to whole articles, we can at least read the abstracts and maybe request articles through our local library.

Seems really interesting David!

I am interested in one article in particular, about the CS: "Resistance of garden roses to cercospora leaf spot"
The abstract states that 6 cultivars showed no cercospora symptoms. Does anyone has access to the full article. It would be really nice to know which 6 cultivars :-)

thx!

I regret that since the fire we have had to cancel about $1 million worth of subscriptions, with a freeze on new acquisitions for this year. SO no luck. WE have the other six symposia (maybe) but they are not retrievable until the library reopens next year.

Characterization of Rosa 'Harison's Yellow' clones using SNP markers (P. Harris, D.C. Zlesak, C. Carlson, F. Ghavami)

The last time I was in San Jose, there were two specimens at the Heritage garden labeled as 'Harison's Yellow'. They are not the same. One was taller and less compact in growth. If opened ifs flowers over a longer period, and on two occasions (each time following a heat wave) some flowers opened that were brushed with red. This one seems to agree with 'William's Double Yellow', which was also introduced to the US early in the 19th century.

Unfortunately, I wasn't aware of the differences at first, so the pictures I took of them are mixed up.

Then there is (was?) 'Hogg's Yellow' that might be around, somewhere. The fragrance should give it away.

Magazine of Horticulture 5: 258 (1839)
We were particularly pleased with several very pretty yellow roses, seedlings of Mr. Hogg's; one of the number was peculiarly fragrant, and also a well formed flower, second only to Harrisonii. None of the kinds are yet named, but we hope Mr. Hogg will designate them in some way that they may be better known and introduced into collections.

The various old yellows are bound to be similar, all being derived from R. foetida. Allegedly.
