Because of limited of water resources in Egypt, rationalize of irrigation water became necessary. Therefore, development wheat genotypes with drought tolerance is very important, especially with the essential need to expand in growing wheat to narrowing the gap between production and consumption. In this study, twenty-one genotypes of bread wheat were evaluated with testing stability of their performance during two growing seasons; 2018/19 and 2019/20 under drought condition at the Experimental Farm of Faculty of Agric., South Valley Univ., Qena.  Drought was applied by two levels after heading 50% of plants; genotypes were irrigated each 14 and 21 days, respectively. Each experiment was designed in a spilt plot arranged in a randomized complete block design (RCBD) with three replications. Results revealed that mean squares due to years, irrigation cycles and genotypes were highly significant for all studied traits, except for days to maturity which did not differ significantly from year to another. Results revealed also that drought caused decreases in estimates of all studied growth and yield traits. The cultivars, Misr 2, Gemmiza 12, Gemmiza 11 and Gemmiza 9 which had highest values of STI with lowest values of TOL, SSI and S were the best drought tolerant cultivars. High estimates of heritability in broad sense were recorded for all studied traits. According to stability parameters, out of fifteen stable genotypes for grain yield (Ard/fed.), the two genotypes line 3 and Shandweell 1 considered to be superior which could be recommended.
