Ann, another reason is that canina has now thought to be the most recently emergent species. Study might help determine if so-called canina inheritance is unique or maybe a standard evolutionary strategy and way-station along the road of speciation. If canina-inheritance can be correlated to glaciations in Europe and insects that lived or evolved during those glaciations, we will have learned a lot about the evolution of at least this section of Rosa.

The reason may be that R. canina has such an unusual "love life" with the seed contributing 28 chromosomes and the pollen only 7. As a result, populations are very matriarchally similar. Establishing differences between populations in different areas might tell something about how evolution happens.

Henry or anyone else,
Do you have any insight as to why the Europeans have so much interest in the genetics of R. canina sensu lato?
I was surprised a decade ago to be told by several academics (North American variety) that if there wasn't research money, projects wouldn't be done. I can only assume that most research world wide has to be driven by research funding. So ....why canina?
Likewise why not gallica, sempervirens, or even spinosissima?
