An eight parental diallel cross was made to study the extent of variability, interrelationship, direct and indirect effects between grain yield and its components. Genotypic variability coefficient was higher for grain yield as compared to other studied characters. Heritability estimates ranged from moderate (66.20%) to high values (96.95%). Number of grain spike 1000 grain weight and plant height were positively and significantly correlated with yield except number of spikes per plant. Path coefficient indicated that except plant height the traits have positive direct effect on grain yield.
