Rosa eglanteria

I brought a cutting of rosa eglanteria with me when I moved. It is hardy and zone 4 and quite clean. It’s also full of rose hips.
Has anyone used it for breeding hardy rose? Can you share your experiences?

Helpmefind list it as synonym of R. rubiginosa. If that’s right, it’s worth to use (such as some Buck and Kordes varieties) but it belongs to caninae group.
