[Evaluation of wheat cultivars for drought resistance]
1988

An experiment was conducted with 35 improved Iranian and foreign wheat cultivars under normal and limited irrigation in order to evaluate their relative drought resistance. The experimental design was a split-plot with four replications with irrigation regimes as main plots and the cultivars as sub-plots. Characters studied were grain yield, 1000-kernel weight, no. of kernels per spike, no. of kernels per spikelet, no. of spikes per unit area, days to head emergence, and plant height. The experiment was fall planted. Irrigation increased grain yield, 1000-kernel weight, plant height, no. of kernels per spikelet, and no. of kernels per spike. Coefficients of correlation were calculated among several characters. The stress and nonstress yield potential under normal irrigation can give some indication of performance of cultivars under limited irrigation. The performance of cultivars with limited irrigation was positively correlated with drought resistance index (r=0.63** )
