Experiment was conducted to assess the magnitude of association and contribution of traits including diseases of yield in wheat. It was observed that days to maturity, tillers plant⁻¹, effective tillers plant⁻¹, grain weight spike⁻¹, grain yield plant⁻¹ and leaf blight-1, leaf blight-2, powdery mildew had maximum coefficient of variation. The high heritability was found for days to 75% heading, plant height, tillers plant⁻¹, spike length and spikelets spike⁻¹, grain weight spike⁻¹, number of seed plant⁻¹ and leaf blight-3. Highly significant positive association of days to 75% heading with grain weight spike⁻¹ and plant height was found correlated with tillers plant^{1 and effective tillers plant−1. However the grain weight spike−1 is significantly positively correlated with grain yield plant−1. Grain weight spike−1 and number of seeds plant−1 were observed positive significant correlation with grain yield plant−1 in wheat}
