Quality of coriander (Coriandrum sativum L.) genotypes grown under Gangetic Alluvial region of West Bengal

The present study was conducted at Horticultural Research Station, Mandouri, Faculty of Horticulture, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal during the year 2014-15 and 2015-16 to evaluate twelve genotypes of coriander (Coriandrum sativum L.). The results indicated the predominant leaf colour was green (58.33%) followed by dark green (41.66%). All the germplasm showed medium basal lobing and trifoliate. The essential oil yield was low in all variety. Arka Isha yields the highest (0.36%) essential oil. The maximum value of oleoresin content was observed in NRCS A.Cr-1 (12.87%) followed by Suvashini. On the other hand the minimum oleoresin was found with the germplasm Assam collection (3.26). Seed yield/plant in different germplasms ranged from 6.17 g in Pant Haritma to 1.15 g in Manipur collection-2. Yield per plot was found highest in Pant Haritma (445.37 g) followed by NRCS A.Cr-1 (384.33 g). Projected yield per ha is concerned highest yield was obtained in Pant Haritma (22.27 q/ha) whereas Manipur collection-1 recorded the least of (7.75 q/ha). On the basis of good performance with Essential oil and oleoresin content, the genotype Arka Isha and NRCS A.Cr-1 respectively can be considered as the most suitable for quality aspects.
