Rosa moschata X wichuraiana

I was out in the sub-freezing weather on Wednesday cutting some brush and got a chance to check out how some of my older species rose hybrids were doing. I have three old F1 moschata X wichuraiana plants still alive but two of them aren't looking all that happy with being totally neglected - no care except for mowing on two sides of them. One of them however is happy as can be. It's a big shrubby thing and covered with hips. Here it is:
And keep in mind that just upwind to the west 20 ft away is a big plant (that's supposed to be Rosa soulieana - it didn't look like my previous plant of that species). But, just like my original soulieana, this one seems to be super susceptible to Rose Rosette Disease, because it's just covered in witches brooms. I wouldn't imagine that the F1 moschata X wichuraiana is immune but it must have at least some level of resistance (to the disease or the mites that spread it) being this close to such a huge source of infection and still being free of RRD. Here's that diseased "soulieana". I just turned around and took the picture, that's how close it is.
Here's a close-up of the hips on the still healthy F1 moschata X wichuraiana. I harvested these and hope to get them in the ground within a few days. 

 And I guess this one probably deserves to have some intentional crosses tried on it next season.
