The analysis of variance revealed significant differences among genotypes for all the characters. Studies of genetic variability revealed high phenotypic and genotypic coefficients of variation, heritability and genetic advance as per cent of mean for the traits viz., number of basal tillers per plant, no. of productive tillers per plant, main ear width, grain yield per plant and grain yield per plot indicating simple selection can be practiced for improvement of these characters. The genotypic coefficient of variation for all the characters studied was lesser than the phenotypic coefficient of variation indicating the effect of environment. High GCV and PCV values were observed for grain yield per plot followed by grain yield per plant, no. of basal tillers per plant, productive tillers per plant, main ear width and finger length. High heritability coupled with high genetic advance as per cent of mean was observed for plant height, number of basal tillers per plant, no. of productive tillers per plant, main ear length, main ear width, finger length, grain yield per plant and grain yield per plot. Thus, these traits are predominantly under the control of additive gene action and hence these characters can be improved by selection.
