| Description |
The karyotypes of 2 cultivars of Zingiber officinale Rosc., viz., Varadha (2n=22) and Sabarimala (2n=24) were investigated for the first time. The karyomorphological analysis of these 2 cultivars differ from each other indicating relatively advanced evolutionary status of cv Varadha as compared to wild cv Sabarimala. Essential oil constituents in cv Varadha reveals 2.5% essential oil and the other major oil components are citral and limonene compounds (2.4%). geranoil (2.3%), zingiberene (42%), arcurcumene (11.4%), pinene, phellandrene compounds (16%) and a-terpineol (2.8%) while in cv Sabarimala ginger has 4% essential oil and the major components in the oil are citral and limonene compounds (3.7%) zingiberene (49%), ar-curcumene (11.5%) pinene and phellandrene compounds (12%), and a-terpineol (1.84). Essental oil components of these 2 ginger cultivars indicates mixed chemotypes, which are know to be gene – controlled.
