Abstract

Twenty five genotypes of tunneric including one wild were evaluated for genetic variability for growth, yield and quality characters for two years. Curcumin content, tillers/clump and mother and finger rhizome yield components showed high genetic variation and broad sense heritability. Yield and curcumin content were negatively correlated. Metroglyph analysis showed wide genetic diversity among the genotypes. PCT-13 and VK-145 were superior genotypes for yield and curcumin content.
