There has been a limited amount of work done, I know. What I don't
know is how extensive it has been. Kim Rupert (roseseek), Paul Barden
(trospero) and Malcolm Manners (malcolm_manners) would be the ones to
ask. These are the go-to guys for all things genetic/lineage/science
related, lol. There's a possibility that UC Davis might be working on
something, since they've done so much work with untangling the
relationships between cultivars of other genera, specifically edible figs. Heck, for all I know, Malcolm might be working on it. He's good like that, lol.

I know that some work has been done on old european roses (Damasks, Gallicas, Albas and Centifolias). A google search might help.

Thank you both - I was just curious. I poked around a bit on the web and didn't find much, but maybe now with names and more precise word searches more will be revealed. cheers!

Thank you TrueBlue - fascinating. Some of the publications look really interesting. I'm very glad to know about this site and should be able to dig a little deeper now. All the best!

Malcolm Manners has done some work at Florida Southern College. I heard him give a talk on it at a HRF conference.
