Genetic variability, phenotypic and genotypic coefficient of variation, heritability and genetic advance was studied for eighty three turmeric genotypes collected from different sources of India including local collections. High phenotypic coefficient of variation, and genotypic coefficient of variation was obtained for number of secondary rhizomes, whereas, highest heritability was observed for curcumin content and curing percentage, indicating that these characters are important in crop improvement which are contributed by additive genes where the improvement can be made by simple selection . The selection for these characters will be more effective in, Vontimitta for number of secondary rhizomes, CLL 335 for number of primary rhizomes and yield per plant and curcumin content for T Sundar. Thus results indicated that in turmeric individual plant selection based on desirable characters could be effectively utilized for extraction of superior genotypes.
