An experiment was conducted to determine the genetic variability, heritability, genetic advance and character association for yield and its component traits in 60 wheat genotypes under timely and late sown conditions. Significant genotypic differences were observed for all the traits in both environments. The moderate magnitude of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) was recorded for grain yield per meter and effective tillers per meter and grain filling duration under timely and for grain yield per meter and effective tillers per meter under late sown condition. Above mentioned traits also showed high heritability coupled with high genetic advance in both the environments. Grain yield showed positive and significant correlation with effective tillers per meter, canopy temperature, but correlated negatively and significantly with plant height under timely sown condition. Under late sown condition grain yield showed positive and significant correlation with days to anthesis, plant height, effective tillers per meter, canopy temperature and grain weight. Path analysis showed that effective tillers per meter had highest positive direct on seed yield followed by days to anthesis, grain weight under both the environments, indicating that these were main contributors to grain yield.
