ABSTRACT The essential oil of 28 ginger genotypes was subjected to gas chromatography–mass spectrometry to understand the potential of these genotypes to produce high essential oil with added value. The essential oil and its composition varied among genotypes. The highest essential oil and oleoresin (6.00 and 12.18 %) was recorded in ‘Red ginger’ (Z ingiberofficinale var. rubrum). Among the ginger (Z. officinale) genotypes, high oil and oleoresin (3.00 and 8.55 %) were recorded in ‘Arunachal local’. The genotypes ‘Acc. 578ʹ, ‘Nadia’ and ‘Aswathi’ recorded less fiber and ‘Red ginger’, ‘Acc. 219ʹ, ‘Arunachal local’ and ‘Acc. 833ʹ recorded high fibre. The Zingiberene was the major component in the essential oil and highest was recorded in ‘Maran’. Principal component analysis revealed essential oil, oleoresin, camphene, trans-nerolidol, α farnesene and neral contributed to genetic diversity. The results contribute to the selection of ginger genotypes for high essential oil and different end use.

印度生姜 (Zingiber officinale Rosc.) 基因型的质量属性和精油分析

摘要 对 28 种姜基因型的精油进行气相色谱-质谱分析，以了解这些基因型生产具有附加值的高精油的潜力。精油及其成分因基因型而异。最高的精油和油树脂（6.00 和 12.18 %）记录在“红姜”（Z ingiberofficinale var. rubrum）中。在姜 (Z. officinale) 基因型中，'Arunachal local' 记录了高油和油树脂（3.00 和 8.55 %）。基因型'Acc。578ʹ、“Nadia”和“Aswathi”记录的纤维较少，“红姜”、“Acc. 578”记录的纤维较少。219ʹ，“阿鲁纳恰尔当地”和“Acc. 833ʹ 记录了高纤维。姜烯是精油中的主要成分，最高的记录在'Maran'。主成分分析显示精油、油树脂、莰烯、反式橙花醇、α 法呢烯和 neral 有助于遗传多样性。结果有助于选择高精油和不同最终用途的生姜基因型。
