An experiment was carried out in the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat during 2017-18, to study their variation in concrete recovery and chemical constituents. The experiment was laid out with six tuberose cultivars in Randomized Block Design (RBD) with three replications. The six cultivars were Arka Nirantara, Shringar, Hyderabad Single, Vaibhav, Suvasini and Mexican Double. Aromatic variation of six cultivars were observed and found that single cultivars contain more concrete % than double cultivars. Cultivar Shringar results highest concrete% among the six cultivars. The chemical composition of the tuberose absolutes was analyzed by gas chromatography-mass spectrometry (GC-MS). Major chemical compound identified benzyl benzoate, geranyl acetate, citral, phenol, alpha-terpineol, fernesol etc. Single petaled cultivars were found more promising for concrete recovery. So these cultivars should be cultivated commercially for industrial purpose. | Assessment of variation in concrete recovery and chemical constituents among the tuberose cultivars in Assam condition
