Analysis of Yield Components and Their Association In Wheat For Arthitecturing The Desirable Plant Type

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}
