Abstract:
The present investigation entitled “Assessment of genetic variability, heritability and genetic advance in turmeric (Curcuma longa L.)” was carried out in randomized block design with three replications during 2016-17 and 2017-18 on two locations to study the variability, character association, divergence and stability and adaptability for twenty characters among thirty two genotypes across four environments. The study revealed that wide range of variation observed for all the traits among thirty two genotypes. Based on per se performance, the genotype NDH-98 produced maximum rhizome yield followed by RH-407, NDH-79, CL-34 and TCP-161 produced highest rhizome yield per hectare. PCV were higher than GCV for all the characters. High estimates of PCV as well as GCV was observed for plant height, number of tillers per clump, number of leaves per plant, plant girth, weight of mother rhizome, weight of primary rhizomes per plant, number of secondary rhizomes per plant, weight of secondary rhizomes per plant, number of tertiary rhizomes per plant, weight of tertiary rhizomes per plant and rhizome yield q/ha in all environments. The high heritability accompanied with high genetic advance was estimated for plant height, weight of fresh rhizome per plant, weight of mother rhizome, weight of primary rhizomes per plant, weight of secondary rhizome per plant, in all four environments (E1, E2, E3, E4).
