Description	Commercial winter wheat varieties were tested in a 4-year field experiment for their yielding ability under optimal and drought-stressed conditions. The grain yield reduction caused by insufficient moisture varied yearly from 45 to 81%. Different drought indices based on varietal performance under drought compared to moisture optimum were calculated and applied for identification of stress susceptible/tolerant varieties. The relationship between indices and relative yield was analyzed by correlation analysis and principal component analysis (PCA). Using PCA, which explained 95% of the total variance, tested varieties were discriminated according to their yield potential and response to drought stress. According to the results, several varieties can be recommended to farmers for drought-prone environments as more stress tolerant.
