Quality Evaluation of Ginger (Zingiber officinale Rosc.) Germplasms under New Alluvial Zone of West Bengal, India

Abstract

The study was conducted at the Department of Plantation, Spices, Medicinal and Aromatic Crops, Faculty of Horticulture, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India during March-May, of 2020 and 2021. The objective of the present study was to evaluate the quality content of 18 ginger germplasm and to identify the most suitable promising genotypes under New alluvial zone of West Bengal. The result of the study shows that maximum essential oil content was obtained from the genotype Surabhi (1.65%) followed by Gorubathan (1.60%), Hui local (1.57%) and the lowest in Takeng local (0.88%). Highest oleoresin content was observed in the genotype Surabhi (7.88%) followed by Hui local (6.42%), Thinglaidum (6.34%) and the lowest was observed in Meghalaya local (3.51%). Maximum dry recovery was recorded in the genotype Gorubathan (23.00%) followed by Surabhi (22.20%), Hui local (22.02%) and the minimum in Moran ada (16.62%). Maximum crude fibre content was recorded in the genotype Takeng local (7.58%) followed by Jorhat local (7.40%) and lowest was with Surabhi (4.49%). Further, the maximum moisture and ash content were observed in Thinglaidum (14.21%) and Moran ada (7.25%) respectively. Thus, the genotypes viz., Surabhi, Gorubathan, Hui local, Thingria, Thinglaidum and Nadia gave an overall appreciable amount of quality content and were considered to be most suitable promising genotypes for their quality content in New Alluvial Zone of West Bengal.
