Response of Twenty Wheat Varieties to Drought Stress Based on Some Agronomic Traits and Molecular Analysis

Abstract

The electrophoretic patterns of leaf water soluble proteins for 20 wheat varieties showed 17 bands. A new band of 60 kDa appeared in the patterns of the varieties Namangan and Kirsehir under drought stress. The protein bands of 23, 20 and 10 kDa were only presented in the pattern under drought stress for Xinjiang Uygur variety. The peroxidase isozymes showed four clear bands at loci of RF 0.075, 0.165, 0.25 and 0.75 which most of the varieties manifested more band intensities in the drought stress patterns than non-stressed plants. The superoxide dismutase showed three clear isozyme bands at loci of RF 0.28, 0.49 and 0.72. Out of the 20 varieties, 13 varieties manifested more band intensities in the drought patterns than the control and 4 varieties manifested the same band intensities under both conditions. The mean performance of agronomic traits for the varieties Sfaqis, Sids8, Giza164 and Trabulus gave high mean values for plant height, leaf area, number of spikes per plant and 100 grain weight, respectively under both conditions and showed high band intensities in the superoxide dismutase patterns under drought stress.
