One hundred nineteen lines/cultivars of wheat (Triticum aestivum and T. durum) were planted in augmented design with 3 checks (PBW 343, UP 2338, WH 542). Data were recorded on 13 characters. The nature and magnitude of variability and character associations were studied. The high value of PCV was observed for grain yield whereas moderate values of PCV were obtained for grains/ear, harvest index, ear length, sedimentation value, biological yield, 1000-grain weight and plant height. Low values of PCV were observed for rest of the characters. Character association analysis revealed highly significant and positive correlation of grain yield with biological yield/plot and harvest index. Other characters which showed positive and significant correlation with yield were grains/ear, hectoliter weight and 1000-grain weight. Days to heading showed highly significant and negative correlation with grain yield. Protein content showed significant and negative correlation with harvest index. Potential donors for different characters have been identified in the present investigation.
