Contribution to yield of cereals has traditionally been studied using yield and various yield components, thus neglecting the role of other organs such as ear awns and flag leaf. Here, we studied the effects of genotypes on the photosynthetic activity of the flag leaf blade and the ear awns of spring wheat. The parameters related to the photosynthetic activity were analyzed in relation to the grain yield and various yield components at maturity. In the present study, ten wheat varieties/lines were tested to find out the effects of flag leaf and ear awns detachment on grain yield. There was much genetic variability among different varieties/lines for different traits. Awns detachment exhibited less effect on yield and yield related characters as compared to flag leaf detachment, while detachment of both had more significant effects than individual treatment. Flag leaf area and some other components showed positive and significant correlation with grain yield. Which suggested that flag leaf + awns might be used a morphological marker, while selecting wheat varieties/lines for good photosynthetic activity and high yield.
