I forgot to mention a prime example of two roses with good vigor and relative hardiness that bred a total trash plant. Spiced Coffee, lol. It was bred from Harmonie (aka Fragrant Cloud 2.0) and Big Purple.
I’ve also had difficulty striking those pithy caned ones and that when I do they seem to do poorly on their own roots. Maybe it’s just my soil or my climate, or my ‘hard-love’ approach to gardening, I don’t know.
Warren, each year I use ‘Golden Chersonese’, which is an ecae/xanthina/hugonis hybrid and every year the crosses fail on me or something happens to the hips. This year, rugosa ‘alba’ x ‘Golden Chersonese’ was looking good and was just starting to colour up and I kept deciding I’d leave it on the bush for just a little longer… then the possums moved in and ate them all 
I don’t think I have any more hips forming with it this year… I guess I’ll have to wait until November/December to try again. I may have a Rosa longicuspis var. sinowilsonii x ‘Golden Chersonese’ still but haven’t checked in a while. I did this one for the same reason Karl mentioned the crossing of Noisette/Teas with foetida derivatives as many years ago I remember Karl making a similar statement of blackspot tendencies being related to the summer dormancy (and therefore shorter lifespan) of foetida’s foliage and the species I used is evergreen here. I’ve put a few foetida dervied yellows onto this species in the hope of introducing longevity into the foliage of yellows. It’s interesting that my little yellow ‘Baby Love’ seedling is also evergreen here and has excellent disease resistance (except to downy mildew).
The pithy ones are bears to root. While you can sometimes get them to root, most often they don’t grow well own root. I don’t know if it’s because the pithy canes don’t store sufficient carbs to make them vigorous or they’re more susceptible to soil diseases or the combination doesn’t produce sufficient root systems. Whatever the reason, pity wooded roses are best budded.
This is a photo I took at Sequoia years ago. They are two Grey Pearl bushes Burling created. They are the same age, from the same mother plant, grown in the same soil, side by side in the same green house. The one in the foreground is own root. The GOOD one is budded.
Just checked on the little ones I have growing 10 mile out of town, to my supprise I could see these bright dk yellow flowers blowing around in the wind. They had been open for a few days and in this ozzie sun showed no sign of fading. The cross was Charles Austin X Bamako and the plant is quite healthy as well.
