A highly black spot resistant breeding line derived from R. wichurana “Basye’s Thornless” (black spot resistant)—J06-20-14-3 (J14-3) according to Dong et al., a moderately resistant cultivar “Old Blush” (OB) and three susceptible cultivars with excellent ornamental characteristics—“Little Chief” (LC), “Red Fairy” (RF), and “Vineyard Song” (VS) were used to generate the three diploid populations (2n = 2x = 14) for linkage map construction

[Listed under "Wild Roses and Their Cultivars"] Basye, USA, 1977. ('Basye's Amphidiploid' x Rosa carolina seedling x 'Hugh Dickson') It is tetraploid and fertile, so is able to be crossed with modern garden roses. 'Basye's Purple' is now in commerce. (Rosa rugosa x Rosa foliolosa)

One cross which I made in 1956 was R. carolina x Hugh Dickson. Among the open pollinated seedlings of this cross was one which, during its first year of growth, appeared to be thornless. During its second year, however, a few thorns appeared on the laterals. I then grew 15 open-pollinated seedlings of this rose, one of which proved to be completely thornless. It bears the number 65-626, being seedling number 626 of the year 1965. This implies that the bees carried out the actual pollinating in the year 1963....
Not only is 65-626 completely thornless, but the midribs of the leaves are perfectly smooth, a property posessed also by its mother. The growth is vigorous to six or eight feet. The flowers are single, pink, small and occur in clusters on strong stems, somewhat reminiscent of R. carolina. The foliage has high resistance to blackspot.
My record book shows that in 1961 I made a somatic chromosome count of the mother of 65-625 and found it to be 28. Apparently I never got around to making the count for 65-626. But over the last 20 years, its wide compatibility with garden roses, both as male and female parent, leaves little doubt that it, too, is a tetraploid.
Selfed seedlings of 65-626 are generally thornless with smooth midribs. Rarely a thorn will appear. But roughly half will have a few fine bristles low on the canes, close to the base of the plant. This is clearly a throwback to R. carolina, which has a generous supply of these latent (recessive?) bristles in later crossings. I would suggest several recessive selflings of 65-626. This was one of my oversights as an amateur.
If 65-626 should, in younger hands, be privileged to play some role in the thornless garden roses of the future, then perhaps it should a name. I have chosen Commander Gillette, for the navigator on the light cruiser, USS Marblehead, on which we both served during World War II.
...The three roses above described, 65-626, 77-361 and the probable amphidiploid are now growing in the Huntington Botanical Garden.
