Abstract
The present research was conducted at Maragheh Research Station on 4 commercial bread wheat cultivars (Sardari, Sabalan, Azar and Ghermezghen) as recurrent parents, and 4 resistant lines as donor parents to transfer the resistance to Tilletia laevis Kiihn to the commercial bread wheat cultivars during 1994-2001. In this study two back crosses were used for transferring of resistance. F1 populations were artificialy inoculated with teliospores of a virulent isolate of Tilletia laevis, and resistant plants were selected. Back cross breeding method was used to transfer common bunt resistance to the commercial bread wheat cultivars. Selfing the second back cross generation, coupled with 3 years of selection of resistant progenies identical to the original parents under artificial infections, prodouced some resistant lines such as Sabalan*2/Kal-Blo"s", Sardari*2/Kal-Blo"s" Sardar*2/4/Ald"s"/Pima77/3/CMH24A.630/Bui"s"//Ch74a.630 to Introduce to farmers for planting.
