Comparative Studies in Relation to Morphological and Biochemical Active Compound in Turmeric (Curcuma longa L.) Rhizome

Abstract

The present investigation on comparative studies of morphological and biochemical active compound in turmeric (Curcuma longa L.) rhizome was carried out Main Experimental Station, Vegetable Science, A.N.D.U.A. &T., Kumarganj, Ayodhaya in Kharif season  in year 2012-2013. One variety and 9 germplasm was selected namely, Prapha, NDH-1, NDH-7, NDH-8, NDH-45, NDH-68, NDH-69, NDH-86, NDH-89 and NDH-116. Regarding morphological characteristic viz. yield of rhizome/plant and length of mother rhizome, NDH-8 recorded highest yield 305.93 g and 10.20 cm, respectively. While the maximum length of finger rhizome was recorded in Prabha (12.23 cm) followed by NDH-8 (11.50 cm). NDH-8 had also recorded highest total mineral content (5.21 %), carbohydrate content (69.50 %), protein content (6.66 %), essential oil (8.21 %) and oleoresin content (13.26 %). NDH-1 had maximum curcumin content (5.8 per cent) followed by NDH-7 (5.6 per cent).     In the light of reviewing physical characteristics and biochemical composition NDH-8 and NDH-1 are recommended as a promising turmeric germplasm.
