In PP10009 Shrub rose plant named `George Vancouver`, it states that the L83 line was derived from a cross between Rosa kordesii and breeding line G49. G49 is a seedling of Max Graf as is R. kordesii.

Rob..........

As I read your comment, the parentage of the rose should be reported as seedling X seedling as the roses used in the cross were unnamed seedlings. Am I reading this correctly ?

Hi Lyn. Felicitas Svejda listed the parentage of L83 as R. kordesii x G49. G49 was a study name for her own tetraploid seedling of 'Max Graf'. I'm thinking that G49 should have its own entry and listed as a seedling of 'Max Graf' hybridized by Felicitas Svejda and L83 should have the parentage listed as R. kordesii x G49. The reason I think these should have their own entries with parentage listed as Felicitas had them is that these roses were important in the breeding of many Canadian roses. Some are still working with L83 and with direct descendants now. What do you think? Thank you!

I put up 'G49' as a rose page and added the parentage to 'L83' as you suggested in your post. I would love to put up more plant characteristics for these roses. Can you email me at HMFRoses @ (at)aol.com ? Delete the (at) in the email addy.

Smiles,
Lyn

Rob Byrnes:

L83 was a line released by Dr. F. Svejda to the scientific community at large for research purposes. Lineage is given in her publication "Rose Germplasm L83" HortScience 23(2): 415-416. 1988. I hope that this will be of use.

All the very best.
