The florist's chrysanthemuml Dendranthema morifolium/Rarest./Tzvel., is a world known flceer, yet-the-problem of its origin has not been solved.-After a brief survey of the history of the flolriet's chrysanthemum in China, as well as concise descriptions of the probable parental wild species, the author laid stress on introducing preliminary achieve-ments in artificial creation of a new species-D. pekinense/Chen and Liang.1963, Chen and Liang 1964; Chen et el. 1981; Chen et al 1982/, being a tetraplold/2n=36/with intermediate characteristics between its maternal parent D. indicum var. acutum and paternal D. erubescens but with white, light pink, light yellow and. yellow semi double flower heads. 3 Peking Daisy cultivars/D. peki-nense/were obtained during 1962-1963, and 10 more cvs./also I plant each/in 1979-1980, all from F seedlings of D. indicum vat. acutumx1 D. erubescens, among many other offsprings of different speelflc hybrids. Beginning from autumn of 1981. artificial cross polllnations were made mostly between D. zawads-kii and indicum slong the slopes of Huang Shah/Yellow Mountain/, Anhui Province with alt. 1450-1680m. The mother plants were potted and transplanted to Beijing, and seeds/achenes in reeality/to be harvested on them during the winter in cool greenhouse. 19 hybrid plants from D. zawadskii X D. in-dicum show intermediate stem and leaf characteri-stics. F1 plants in bloom during the coming autumn will probably'throw new light on solving the origin problem. Further investigation projects, includin6 cross combinations with D. vestitumas one of the hybridization parents, also including some cytological observations with chromosomes of the parental wild species as well as those of the F1 hybrids are suggested.
