Liz, thanks for the great summary! I wish that I could have attended the meeting.
…A funny thought. I have a brother named “Thomas Sproul”. When I read “Thomas Proll”, it sounds just like my brother’s name, but then I am probably not pronouncing it right…!

‘Rosy Vision’ which was given to the Canadian Rose Society in celebration of their 50th anniversary. Limited availability in Canada was from Palatine Roses, Niagara on the Lake, ON but I have no idea of its availability at this time. Line 05-01, line 07-01-S, line 01-60 and many others which can be seen at www.northernhybridroses.com. Don’t forget -40F is the ambient temperature + wind chill.
Pierre Ruten: What you indicate does not always hold at least based on my experience. Perhaps a good number of seedlings were the exceptions - I am not sure at this point.
Et al: Black spot tends to develop in late summer (end of August and early September) and early fall on the most resistant roses. I guess the term ‘disease resistance’ has a different meaning for possibly each breeder, each Rosarian, etc. and a specific definition doesn’t exist. What seems to be acceptable to one person is unacceptable to another. Perhaps I will have to call my lines with minimal black spot 'disease resistant’and leave it at that.
I do raise/breed HT’s with no spray, Pierre. I have a mass assortment of rose classes in my garden and mix them at whim. And I do get some healthy specimens.
Thank you for the information Neville and the link as well. I’ll check that site out.
Liz, you mention there was talk about the differences in what the European buying public wants vs what North America wants, and what rosarians look for vs the general buying public. I’d like to now more on this topic; can you please elaborate some more?
As for Kordes…I wish them luck in ‘shattering the perceptions that roses are difficult plants to grow’ in areas that harbour Japanese beetles. A disease riddled rose is the least of one’s worries when such monsters prevail.
Dee. S, Neem (if it contains azadirachtin) repels Japanese Beetles. It is systemic and has been applied and studied as a soil drench. I hope that it will not be long before someone offers it in a kit to directly inject into the trunk of the rose.
I had intended to include this abstract with the last post.

Neville,
Thank you again for the link to www.northernhybridroses.com There are some very attractive roses there. I was disappointed that parentage wasn’t listed for each line tho.
Not my opinion just facts.
Compared with most ornamental plants roses are outstandingly difficult to ameliorate.
Any other plant is a lot easier.
I.e. all orchid seedlings are nice and all are sold at good prices years before first flower.
How many seedlings for a sellable rose var: tenth of thousands.
How many are innovative or steps forward and will be sold by significant nurseries 20 years later: some say one percent.
Kordess is not alone: all professional rose breeders are after desease resistance.
They need new roses that consistently grow out of their own garden…
That’s why I grow several camelias instead of OGR’s, Pierre 
Similar bloom style. Better plants. Neat color patterns. But, then again, most Ericacae plants thrive like weeds where I live, lol.
Dee, If I remember correctly these were the differences. Thomas was saying that in general regarding buying preferences — men tend to like stronger colors such as red, women prefer colors more in the pastel range. North Americans like mauves, while Europeans are not interested buying mauve roses. The general buying public wants a hybrid tea form and has no use for singles, while rosarians appreciate singles.
Someone asked about breeding for insect resistance and while he felt that it may certainly be possible, it was not something that they wanted to add to their list of selection criteria.
Playboy seems to be one of the few that broke the single mold. That is probably because it is so bright and large, yet in clusters.
I do not know a girl alive here that does not like some shade of mauve.
The majority of the males I know love orange or red, and some like dark purple.
My favorite is usually orange blend, bright yellow or gold blended red.
