Morphological Response of Various Genotypes to Drought Conditions

M. Usman Khan, Muhammad Aslam Chowdhry, Ihsan Khaliq and Rashid Ahmad


The experiment was conducted in greenhouse and field under moisture stress condition using twenty four spring wheat genotypes. Inter-relationship among different characters were estimated by simple correlation and path-coefficient analysis. Simple correlation indicated that survival rate, root/shoot ratio, root density, number of veins, flag leaf area, plant height, number of tillers per plant and 1000-grain weight showed positive and significant association with grain yield. Whereas, path-coefficient analysis revealed that 1000-grain weight, root density and stomatal frequency, are the characters which exerted maximum direct positive effect on yield, respectively.
