Drought tolerance levels in some wheat lines and cultivars based on uniform regional wheat yield trial (URWYT-M-75) were investigated using a strip plot design based on complete block design with 3 replications for two years (1998-2000) in Torogh Agricultural Research Station (Mashhad, Iran). The main plots (horizontal factor) were composed of 3 levels of irrigation (10, 20 and 30 days interval), while the sub-plots (vertical factor) were of 20 lines or cultivars of spring bread wheat set up for URWYT (M-75-1-20). Sowing date and sowing and fertilizer rates were under normal condition. Soil water content was also determined. The results showed that when irrigation interval was 10 days, the line yields of M-75-8, M-75-6, M-75-2 and M-75-16 were higher than other lines. When the irrigation interval was 20 days, the highest lines were observed for M-75-2, M-75-14, M-75-16 and M-75-12. In 30 days irrigation interval, the lines of M-75-15, M-75-4, M-75-2 and M-75-14 had maximum yields. As a summary, M-75-2 line was better than others showing good flexibility and water use efficiency, under normal and stress conditions.
