I bet this would be an excellent rose to hybridize with. I mean, it's a tetraploid, so it's fully compatible with modern HTs. So basically, this rose could be a good scaffold for a more formal flower. I could imagine a cross with Mr. Lincoln to give it better disease resistance. It has all of the basic genetics for rebloom and good foliage, and the flower form is nice and simple. It probably carries genes for damask fragrance.

Mr. Lincoln doesn't have particularly good resistance to disease. It survives defoliation because of its inherent vigour, but it's not resistant as such.

Oh, yeah, when I say "give it better disease resistance" I'm referring to improving Mr. Lincoln. I think Portlandica and Autumn Damask could be kind of a good fallback point for creating better hybrid teas. I also think that some species roses would be a good idea to add back into the rose gene pool to get better disease resistance and vigor. Rugosa, bracteata, moschata, and fedtschenkoana are all really good.

'Duchess of Portland' gets blackspot very badly.

If going for red, Roundelay would probably be a better option than Mr Lincoln

What do you think about Dark Desire by Kordes? I have heard a lot of good things about its disease resistance.
