Abstract

Ginger (Zingiber officinale) is a commercially significant plant, valued for the production of ginger extract and bioactive compounds, including oleoresin and essential oils. Quantitative and qualitative traits related to drug-yielding potential were analysed to identify elite ginger genotypes. The analytical technique high-performance liquid chromatography (HPLC) was used to quantify major bioactive compounds in the fresh rhizomes of ginger. In the study of gingerol derivatives, the highest content of 6-gingerol (10.2 %) was found in genotypes from the North Eastern Ghat region. The highest concentration of 8-gingerol (2.9 %) was collected from the Western Central Tableland, while the South Eastern Ghat region showed the highest level of 10-gingerol (1.9 %). Additionally, the North Eastern Ghat region also recorded the highest content of 6-shogaol (1.7 %). Among the selected genotypes, the highest content of rhizome essential oil (1.76 % ± 0.13) was recorded from the Eastern Ghat Highland region. The highest ginger extract content (15.64 % ± 0.25) was also observed in genotypes from the Eastern Ghat Highland region, while the oleoresin content (15.67 % ± 0.46) was highest in genotypes from the same region. Based on mean and standard deviation (SD) comparisons using SPSS test at p < 0.05, significant variation was observed among the 150 genotypes for essential oil, oleoresin, ginger extract and major bioactive compounds. Five elite genotypes were identified, showing high levels of essential oil, oleoresin, ginger extract and key bioactive compounds, including 6-gingerol, 8-gingerol, 10-gingerol and 6-shogaol. These genotypes, collected from different districts of Odisha such as Koraput, Malkangiri, Ganjam, Sonepur and Rayagada are recommended for commercial cultivation in specific regions under various agro-climatic conditions.
