Abstract: The present investigation 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, and stability and adaptability for twenty two 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 NDH-1, NDH-74, NDH-16, NDH-11, NDH-15, NDH-79, NDH-68 and NDH-114 produced highest rhizome yield per hectare. At phenotypic level essential oil exerted highest positive direct effect on rhizome yield followed by weight of fresh rhizome per plant, width of mother rhizome, weight of secondary rhizome per plant. However, weight of mother rhizome per plant exerted highest negative direct effect on rhizome yield followed by dry matter per cent and curcumin.
