Genotypic variability correlation and path-coefficient analysis in turmeric

Abstract

Data on 18 biometric characters of 19 varieties of turmeric gathered from a field trial were analysed and the various genetic parameters estimated. High heritability estimates were manifested by girth of mother rhizome at centre and height of the plant. The expected genetic gain from plant height was also high. The correlation studies revealed that all characters were positively related to yield. Path-coefficient analysis showed height of the plant and length of secondary finger were the major contributors towards the rhizome yield.
