Genetic variability in turmeric (Curcuma longa L.)

Estimates of genetic parameters for 14 characters in 108 collections of turmeric (C. langa L.) revealed significant variability for all the traits. Moderate to high heritability coupled with good genetic gain was observed for weight of mother finger and secondary rhizomes and number of secondary rhizome. Yield per bed had moderate heritability and genetic gain. pev estimates were higher than the Gev estimates for all the traits studied. The estimates of genetic parameters revealed scope for further improvement of rhizome yield by selection.
