Rosa rugosa and its hybrids.
...It would seem as though many of these Rugosa hybrids might be useful in producing new varieties of hardy roses. [...] For the convenience of those amateurs who are doing breeding work with roses, the pollen of the hybrids in the Arboretum's collection has been examined in the Cytological Laboratory.  In the following discussion the percentage of fertile pollen, as determined by microscopical examination, is reported for each hybrid where buds were available for study.
Lady Duncan (R. rugosa X R. Wichuraiana).
Pollen fertility 20%.
A vigorous trailing rose, useful for holding banks, but not suitable for growing on a trellis.  Flowers very large, fragrant, single and a vivid, clear pink.  Foliage dark green, resistant to black spots.  This was one of the hybrids produced by the Arboretum's first propagator, the late Jackson Dawson.

Jackson Dawson, for a lifetime and until his death the gardener and propagator at the famous Arnold Arboretum, near Boston, first considered the value of Rosa multiflora and R. wichuraiana as parents... [he] successfully produced (in 1888) the yet [McFarland was writing in 1929] greatly admired 'Dawson' climber. He sent out 'Lady Duncan' as probably the first Wichuraiana hybrid, and his lovely 'Wm. C. Egan' in the same year united Wichuraiana and 'General Jacqueminot'. His little-known 'Sargent' rose, described by those who have it as a glorified apple-blossom, united both multiflora and Wichuraiana with the Hybrid Perpetual blood.

Rugosa Hybrid Roses have a great future before them in the colder parts of New England since they combine great hardiness with handsome blossoms. The hardiness they get from the parent R. rugosa, a very old inhabitant of gardens, native of the northeast Asia littoral and abundant in Japan, where it is known as the Sea-tomato from the size and color of its fruits. Being a maritime plant it has special use for seashore gardens, and this combined with its hardiness give it a field of wide usefulness. Two Hybrid Rugosa Roses were raised in the Arboretum by the late Jackson Dawson. One, named Lady Duncan, obtained by crossing R. rugosa with R. Wichuraiana, is of trailing habit with glowing rose-pink blossoms. Another is R. arnoldiana, whose parents were R. rugosa and the Rose General Jacqueminot. The Arnold Rose is a bush with erect stems, good foliage, and large, rich red, single flowers.

W. C. Egan, Highland Park, Ills. 'The 'Lady Duncan' Rose (see Plate X, facing page 80) is also a ruggedly hardy hybrid of R. rugosa and R. Wichuraiana, produced, in 1900, by Jackson Dawson, of the Arnold Arboretum, one of the first Americans to appreciate the possibility of R. rugosa as a parent plant in hybridization. The similarity to the parents is well divided, the flower resembling the pink form of Rugosa and its foliage that of the Wichuraiana, while the habit of growth is a compromise between the upright form of one parent and the trailing habit of the other. 'Lady Duncan' is a profuse June bloomer, and always handsome in its glistening foliage, which remains in good condition the season through. The plant illustrated in Plate X was sent me by Mr. Dawson before it was named, and is now some 10 to 12 feet in diameter. I tried to train it up, but it showed evidence of displeasure. I removed the "harness," and it soon showed signs of joy by increased growth and denser foliage. The name, "Lady Duncan," implies English origin, and this fact aroused my curiosity and started me on a hunt to discover the "whys and wherefores." I found that Mr. Dawson had at one time been in the employ of an American family whose daughter married the youngest son of a Scotch peer named Duncan. Dawson was treated very kindly by this family, and he had great affection for them. He named the rose after the daughter, who was never "Lady Duncan," however, as she died before her husband became a lord.

Rose breeders are singularly reticent about the plants they have used in their work, and there appear to be no printed records of the parentage of any of the Rugosa hybrids with the exception of the two which have been created in this Arboretum.  
...The two Rugosa hybrids raised by Dawson at the Arboretum have proved to be good garden plants.  In habit Lady Duncan resembles R. rugosa repens alba but the stems are not as stout; it can be used as ground cover or trained on an arbor or trellis.  The flowers are rather smaller than those of R. rugosa and pure pink, and the leaflets are smaller and very lustrous.  This Rose was obtained by crossing Rosa rugosa with R. Wichuraiana.
