芳香シクラメン'香りの舞い' 埼玉県育成となっていますので、たぶん園芸試験場の作出品種でしょう。常緑の原種プルプラッセンスと園芸品種（原種パーシカムから改良されています）との種間雑種です。論文にもなっていますから、詳細は以下を参照ください。 Hiroshi Ishizaka and Junjiro Uematsu Euphytica 82 (1) 31-37 (1995) Interspecific hybrids of Cyclamen persicum Mill. and C. purpurascens Mill. produced by ovule culture Summary> Interspecific crosses were made to introduce the scent of flowers of C. purpurascens into C. persicum cultivars and ovule culture was used to rescue the abortive hybrid embryos. Cultivars of C. persicum diploid (CPD, 2n=2×=48) and C. persicum tetraploid (CPT, 2n=4×=96) were the pistillate parents and wild species of C. purpurascens (CP, 2n=34) were staminate parents. After pollination, crossed ovaries were collected periodically and examined using paraffin sections. Histological observations suggested that both hybrid ovules of CPD x CP and CPT x CP should be transferred to culture medium 35 days after pollination. Based up on this observation, crossed ovaries were collected 28 days after pollination and ovules with placenta were transferred to MS (1962) medium containing 3% sucrose. These ovules were cultured in the dark at 25° C. The hybrids (2n=41) derived from CPD x CP had the scent of C. purpurascens, whereas the hybrids (2n=65) derived from CPT x CP had the scent of C. persicum. Although both hybrids had complete genomes from the parents and produced a few viable pollen grains, they failed to yield viable seeds by self- and cross-pollination with fertile pollen grains of C. persicum cultivars.

The chemical constitution of volatile compounds of C. persicum (2n=2x=48, AA or 4x=96, AAAA) was distinguished by sesquiterpene hydrocarbons, whereas that of volatile compounds of C. purpurascens (2n=2x=34, BB) was distinguished by alcohols, aldehydes and esters of monoterpene or an aromatic class. The chemical constitution of volatile compounds in the hybrid (2n=41, AB) the amphidiploid (2n=82, AABB) and the sesquidiploid (2n=58, ABB) closely resembled that of volatile compounds in C. purpurascens. By contrast, the chemical constitution of volatile compounds in the sesquidiploid (2n=65, AAB) resembled that of volatile compounds in C. persicum. Flowers of diploid or tetraploid C. persicum had a woody or powdery fragrance, whereas those of C. purpurascens had a rose- or hyacinth-like fragrance. Flowers of the hybrid AB, the amphidiploid AABB and the sesquidiploid ABB had a fragrance resembling that of C. purpurascens, whereas those of the sesquidiploid AAB had a fragrance resembling that of C. persicum. Based on the present analyses, the relationship between the expression of volatile compounds and genome constitution is discussed.
