This study was investigated in randomized completed block design with four replication on 14 crosses from third backcross hibrids in comparison with commercial cultivars Varamin , Sahel, Bakhtegan ( controls) at four research station for two years (2006- 2007).on the base of results of Mean comparison yield in every locations indicated that, El22*tashkand, lamberit*termez, saicala*termez, saicala*bakhtegan and 82041-6*tashkand hibrids with (4049،3958،3922،3916 ) kg/h seed cotton were beter than another hybrids and sahel variety(control) with 3610 kg/h in Hashemabad station , El22*termez, saicala*bakhtegan and siokra324*sahel hybrids with (3446,2, 3388،3214,6 kg/h) seed cotton were better than another hybrids and control with (2897 kg/h) in Kashmar station. In Varamin station Bahtegan *siokra1-4 and Termez*saicala hybrids were the best at some charactors. In Darab station El 22*termez, bakhtegan and saicala*bakhtegan hybrids with( 3654, 3571،3492) kg/h seed cotton were superior. 82041-6*tashkand hybrid was the smallest with good earliness and number boll and lamberiht*termez hybrids was the best in wieht boll in every regions. combined Analyses of variance showed that year and location effects on qualitative and quantative properties hybrids were significant and indicated about introduce high stability with high yield hybrids. on the base of the combined mean comparison ( 2 years and 3 location) El22*termez and Sicala * bakhtegan hybrids with 3725 and 3692 kg/h seed cotton were in the higher groups and introduced as high stability and superior hybrids.
