'Dwarf stature' maize variety offers promises to withstand unfavorable growth environments of Kharif season. But, for developing such variety, dwarf stature inbred lines must be available. Here, twenty-four F3 populations white were evaluated though assessment their genetic variability, heritability, and character association selection promising based on yield parameters. The developed from F1 hybrids following the pedigree breeding method. Analysis variability showed that significant variations existed among characters viz., plant height, cob number grains row-1, plant-1 highest heritability advance. correlation revealed was positively significantly associated with length, diameter, row-1. path coefficient analysis indicated rows cob-1, row-1 100-grain weight had positive direct contributions towards indicating these attributes might considered selection. Finally, upon criteria maturity, base potential, G14 G4 may selected high grain yield, while G10, G11, G12, G1, G3, G16 as lines.
