Wheat as a strategic crop has increasing demand in Iran. So, yield improvement especially through breeding program is very necessary and it dependents upon the screening of a wide range of germplasm to find tolerant and high yielding varieties under heat and drought stresses. In this research, 126 bread wheat genotypes were evaluated in four separate experiments at Gachsaran, Gonbad, Khoram Abad, and Moghan agricultural research stations in 2010-11. This four advanced experiments (A1, A2, A3, A4, A5, A6 and A7) include 18 genotypes, carried out in randomized complete block design with three replications. In A1 test, lines no. 3, 7, 10 and 13 have more yield and optimum level of the other considered traits in compare to check. In A4 test, based on grain yield as the most important trait and the other agronomic traits, lines no. 11, 14 and 15 were selected. Also, lines no. 2, 5, 6, 11, 13 and 17 were the best in A5 test. These lines had partially earliness, optimum thousand kernel weight and agronomic score. Moreover 1 and 3 lines were selected in A6 and A7 yield trials.
