ABSTRACT
Nineteen turmeric genotypes were raised in randomized block design to study the Variability, Heritability and Genetic advance of growth and yield characters during the year of 2012-13. Variability accompanied the PCV estimates were higher than GCV indicating the role of environment. High Heritability was observed for the characters viz, plant height (94.82cm), number of tillers per plant (80.97), number of leaves per plant (92.77), petiole length (80.36 cm), leaf area index (69.28 dm2), number of mother rhizome (89.34), number of primary fingers (89.48), number of secondary fingers (95.05), Weight of mother rhizome (94.08), Weight of primary rhizome (98.73), Weight of secondary fingers (97.55), Length of Mother Rhizome (97.55), Length of primary fingers (87.14), Length of secondary fingers (75.30), Fresh rhizome per plot (79.92), Fresh rhizome Yield per hectare (96.72)suggesting that selection will be effective for these characters. High heritability along with high genetic advance as a per cent over mean for characters viz, Plant height, Number tillers per plant, Number of mother rhizome, Number of primary fingers, Number of secondary fingers, Weight of mother rhizome, Weight of primary fingers, Length of primary fingers, Length of secondary fingers, Fresh rhizome per plot, Fresh rhizome Yield per hectare, hence there is ample scope for improving these characters for direct selection.
Key words: Curcuma longa L, Genetic variability, GCV, PCV, Heritability, Genetic advance over percent mean.
