Abstract

A co ordinated variety trial of turmeric in seven selected germplasms were organised in the year 2010, 2011 and 2012 in experimental plots of the field gene banks of Uttar Banga Krishi Viswavidyalaya in order to investigate the best performing varieties against the check (TCP-2). The characterizations were done in accordance with the norms adopted by IISR (Indian Institute of Spices Research). Conservation of turmeric was done taking qualitative and quantitative characters. The germplasms showed maximum result in plant height (TCP 129), tiller number (RH-50), number of leaves (TCP-129), pseudo stem girth (RH-50), leaf length (TCP-129), leaf breadth (RH-9/90), yield per plot (TCP 70), weight of clump (TCP-129), wt of the mother clump (TCP-129), length of mother rhizome (TCP-129), number of mother rhizome per clump (RH-80), number of primary fingers (TCP-70), wt of primary fingers (TCP-70), length of primary fingers (TCP-129), number of secondary fingers (TCP-2), wt of secondary fingers (RH 80), length of secondary fingers (TCP-2), projected yield (t/ha) (TCP-70), curcumin (%) (TCP-2), oleoresin (%) (TCP-2) and essential oil (%) (TCP-2). From the investigation, TCP-129, TCP-70, RH-80 can be considered for better performing varieties in this region of West Bengal.
