Abstract:
The present investigation was carried out to study the genetic variability parameters and nature of associations among the traits affecting grain yield in twenty three little millet genotypes at Regional Agricultural Research Station, Chintapalle during kharif, 2011. The estimates of genotypic and phenotypic coefficients (GCV and PCV) of variation were moderate for all the traits indicating little influence of the environment on estimates of these parameters. Correlation analysis revealed that, the genotypic correlation coefficients in most cases were higher than their phenotypic correlation coefficients indicating the association is largely due to genetic reason. Number of productive tillers exhibited highly significant positive correlation with grain yield both at phenotypic and genotypic level. Path coefficient analysis showed that number of productive tillers had the maximum direct effect on grain yield followed by plant height.
