Abstract

Eighty elite lines including ten standard varieties of chickpea were evaluated for various seedling parameters. Positive and
significant genotypic and phenotypic correlations were found for different parameters like seedling length, root length, root/shoot ratio, seedling biomass, leaf length, leaf width and leaf area while root length was positively and significantly correlated with other parameters. Root/shoot ratio was positively and significantly correlated with all parameters. Seedling biomass had positive and significant genotypic and phenotypic correlations with all the parameters. Leaf length, leaf width and leaf area also had positive and significant correlation among each other and with other parameters. The estimates of the heritability were high for seedling length, root length, moderate for the root/shoot ratio, seedling biomass and primary leaf area and slightly low for the primary leaf length and leaf width. Higher estimates of heritability and positive correlation coefficients for seedling length, root length, seedling biomass, leaf length, leaf width and leaf area suggest that selection of elite genotypes at seedling level might be effective for further breeding programme.
