| Research Abstract |
Medicinal properties, curcumin and essential oil, accumulated in rhizomes were compared among different cultivations and different lines to evaluate the quality with the yield in Curcuma species. Contents of curcumin and essential oil increased with the development of rhizome, and closely related to rhizome yield. Higher rates and contents of curcumin and essential oil were basically observed in foreign C. longa than in domestic C. longa. Genetic analysis suggested that the difference of curcumin content among the various lines of C. longa was caused by hybridization and introgression between foreign C. longa and other Curcuma species. Detail system diagramwas made to elucidate genetic affiliation.
