Two wheat promising lines selected from compatibility tests along with Sirvan (a new drought resistant variety), parsi and Sivand (two new released varieties for irrigated condition) and Pishtaz and Bahar (two breeded variety) evaluated in a randomized complete block design (RCBD) with three replications, in two locations of Varamin city (Hajiabad and Khaveh villages). Plant height, number of days to heading, number of days to maturity, total kernel weight, biological yield, grain yield and harvest index were measured. The result of combined analysis of variance showed a significant difference at 1% for grain yield, biological yield, number of days to heading and number of days to maturity and a significant difference at 5% for 1000 kernel weight, plant height and harvest index between 7 genotypes. The WS-90-18 and WS-90-10 lines had the same grain yield compared with Sirvan test genotypes. These two lines are suitable for using in these regions. Key words : wheat, elite lines, drought stress, yield, on-form
