In the present study the effect of normal and late sown conditions on the grain growth and yield determining parameters in three contrasting wheat genotypes were determined. Studies revealed that HD 2329 showed maximum yield under normal sown conditions whereas under late sown conditions it was maximum in HD 2285. It was attributed to well poised yield determining parameters developing in vegetative as well as reproductive phases. Kalyansona performed better than HD 2329 under late sown conditions, and this was perceptible in terms of grain weight and not in grain number. Present observations suggests that tolerance for both grain number and grain weight are important under late sowing but grain number is more important for sustaining the growth under these conditions.
