Abstract

During the present research work, Fifty Indigenous inbred lines were evaluated during Kharif 2018 for yield and yield contributing characters. Correlation analysis revealed that grain yield was positively and significantly correlated with Germination %, Ear height(cm), Cob Length(cm), Cob width (mm), No. Rows per cob, Grains/ Row (no.), Dehusk cob weight ( g), Rind weight(g), Test Weight(g), while, grain yield was negatively correlated with Shelling percentage. Path analysis revealed that highest positive direct effect of Dehusk cob weight on grain yield followed by Shelling %, Ear height, Days to 50% tasseling, Test Weight, Grains/ Row, Cob width.
