Screening bread wheat genotypes for drought tolerance 1- germination, radical growth and mean performance of yield and its components [electronic resource].

Seed germination decreased as osmotic potential became more negative. Inhibition of seed germination was greatest under the lowest osmotic potential, - 1.5 MPa. Cumulative germination after ten days ranged from 52.6% to 97.9% for the control compared to 27.4% to 69.8% at -1.5 MPa indicating more pronounced differences among genotypes at the lower osmotic potentials. Accordingly, ten bread wheat genotypes were selected and significantly varied for all traits tested under different irrigation treatments in each location. Reduction percentages for different studied traits . under water stress treatments relative to control treatment was detected and susceptibility index was also calculated for each genotype under severe water stress treatment.
