The present investigation was conducted with the objective to estimate genetic variability, character association and path analysis for yield and yield contributing characters in wheat. The experiment was carried out with 36 wheat genotypes and data were recorded for 13 characters. Highly significant differences among the genotype were revealed by analysis of variance for all the characters. High estimates of variance reflected for plant height, number of grains per spike, harvest index, biological yield and grain yield indicated that they could be considered in selection for improvement of the crop varieties. Correlation analysis revealed that grain yield showed highly significant positive correlation with biological yield while significant positive correlation with tillers per plant. Highly positive direct effect on yield was recorded for number of grains per spike followed by spike length, awn length, plant height and 100 grain weight at genotypic level as revealed by path coefficient analysis. The finding of present investigation might be use full to the future breeding programmes for developing improved genotype. On the basis of study, the desirable donors for each character were identified. The most promising donors for grain yield were WP710/17, HD3189, WP708/17 TALL-1 and PBW343. These genotypes can be used for further breeding programme to improve the yield potential of the variety.
