Abstract :

A biometrical investigation on genetic variability, genetic advance, heritability, character association and path coefficient analysis was conducted taking fifteen ginger genotypes and five yield attributing traits for making clonal selections. Significant genotypic differences existed among the genotypes for all the characters studied. High value of phenotypic coefficient of variability(PCV), genotypic coefficient of variability(GCV), heritability and genetic advance as per cent of mean values indicated scope for improvement in rotting percent, dry recovery per cent, oleoresin per cent and fresh rhizome yield. Both at phenotypic and genotypic level, fresh rhizome yield was found positively and strongly correlated with dry recovery per cent and oleoresin per cent and negatively significantly correlated with rotting per cent. Path analysis revealed that the significantly positive associations of fresh rhizome yield in ginger with dry recovery per cent and oleoresin were due to high positive indirect effect via rotting per cent. Correlated response to selection revealed that, low rotting per cent in genotypes was increased the dry recovery per cent and fresh rhizome yield in ginger. So, due emphasis may be given to low rotting and high dry recovered genotypes in yield improvement.
