In this study, forty-six sweet corn inbred lines were evaluated to assess the variability and association among 11 yield and yield attributing traits at College Farm, College of Agriculture, Rajendranagar, PJTSAU. The traits plant height, ear height, cob length, cob girth, number of rows per ear, number of kernels per row, cob weight with husk and cob weight without husk have shown moderate to high range of PCV, GCV, heritability and genetic advance over mean displaying the importance of these traits in selecting superior sweet corn inbreds. Critical analysis of results obtained from correlation and path analysis revealed that the traits cob length, cob girth, number of kernel rows per ear and cob weight without husk posses high positive significant associations and positive direct effects. From this study it was concluded that cob length, cob girth, number of kernel rows per ear and cob weight without husk are the key traits to be given prime importance during selection for further improvement of production as they exhibited significant positive direct effects with cob weight with husk.
