Abstract: In order to estimate genetic variability, selection parameters and their association analysis for nine traits of wheat, 15 hybrids were synthesized in a 6×6 diallel fashion excluding reciprocals. Analysis of variation established significant relationship for most of the traits that reveals existence of genetic variability for these traits. The PCV values were greater than GCV indicating little influence of environment in expression of traits. High value of heritability along with genetic advance was observed for days to maturity. Genotypic correlations found to be greater than phenotypic correlations for all the traits. Days to maturity (0.63), number of productive tillers per plants (0.202), number of spikelets per spike (0.732) and number of grains per main spike (0.410) exhibited the positive direct effect on grain yield. Therefore, selection for grain yield via these traits will be effective.
