One of the thorniest roses that ever graced my garden is a probable amphidiploid arising in 1967 as a tetraploid seedling of the diploid cross R. abyssinica x R. rugosa, which I made in 1955. In 1975 I applied to this horrendously thorny rose the pollen of 65-626. One of the seedlings, 77-361, was not only thornless and free of bristles but had perfectly smooth midribs!
....The three roses above described, 65-626, 77-361 and the probable amphidiploid are now growing in the Huntington Botanical Garden.
