Species roses go well from seed,. I don't use a fridge, I use a garden or a cold GH. Rosa rugosa sown in October was flowering by summer. Not a big display but the bushes were a couple of feet high and enough flowers for me to know which ones to keep and which ones to give away.
Hybrids/cultivars will grow from seed if the make any but who knows what you might get.
