Analysis of Genetic Diversity and Relationships in the China Rose Group
(2009) Page(s) 29. Triploid...Adam [Provenance: Antique Rose Emporium]
(2009) Page(s) 35-36. Perhaps the most easily noted detail revealed about the China Roses by the similarity matrix though, was how many accessions had identical SSR profiles. The "C25 grp" on the dendrogram represents the China Rose cultivar Old Blush, with the group's oldest recorded date of introduction into Europe of around 1752 (Cairns (ed.), 2000), and the eight synonyms or sports found in this study: 'Climbing Old Blush', 'Green Rose', 'Single Pink', 'Rouletii' [all ex Antique Rose Emporium], 'Pompon de Paris' [ex Ralph Moore], 'Bengale d'Automne' [ex Vintage Gardens], 'Archduke Charles' [ex ARE], and an R. chinensis var. semperflorens [ex Flower Research Inst., Yunnan]. This large group of synonyms and sports still actively propagated and sold in the trade demonstrates how important 'Old Blush' continues to be, long after being used as a parent of importance in the breeding of modern roses. ......'Archduke Charles' also looks reminiscent of 'Old Blush', and shares the characteristic pale pink blushing, changing to much darker pink flowers, but with more exaggerated colors and a higher petal count (Dickerson, 1992). 'Archduke Charles' has been referenced as a possible seedling of 'Old Blush', but the accession in this study had the same SSR profile as Old Blush, and would therefore be a sport.

(2009) Page(s) 52. 'Arethusa'...seems to have some Tea influence based on similarity and its coordinates in the Figure 5, but it is classified as a Hybrid China with unknown parentage bred in 1903 (Cairns (ed.), 2000). Because this accession also has a chloroplast sequence that is unique in this study, it does not give a clear indication of what species or group may have had a maternal contribution to this hybrid.

The rose sampled in this study was identical to 'Old Blush', and though propagated as a separate cultivar, the source was not convinced it could be distinguished from 'Old Blush', but was perhaps a more refined form of it....
