Ten varieties/lines of wheat (Triticum aestivum L.) were planted in a split-plot arrangement to study the effect of flag leaf removal on grain yield and its components. The genotypes differed significantly for flag leaf area, stomatal frequency and yield parameters while leaf venation and protein content were not significantly different. Flag leaf removal significantly reduced plant height, number of grains per spike, 1000-grain weight and grain yield while grain protein content significantly increased. Flag leaf removal did not show any significant effect on number of spikelets per spike. Association of flag leaf area with 1000-grain weight and grain yield was positive and significant while protein content was shown to be negatively correlated with grain yield
