Abstract: Agropyron glaucum which was systematically selected for three years as male parent was crossed with FS progeny material of wheat variety "Keqiang" of geographically distant hybridized with "Nanda 2419" as female parent, In order to eliminate F, sterility,prolonging fertility method was adopted. Zhong 4 and Zhong 5 were obtained through nine years continuous selection breeding, Zhong 4 and Zhong 5 have high resistance to wheat yellow dwarf virus, have immunity or high resistance to many physiologic forms of stripe, leaf and stalk rust disease and possess high protein (17,08-17.13 % content),and high lysine (0.48-0.50%content) etc.Therefore,they are superior resources for excellent synthetic wheat with multiple resistance, When zhong 4 and Zhong 5 were crossed with common wheat,the resistant genes to whaet yellow dwarf virus were successfully transferred to common wheat,and new varieties (lines) such as Shaanmai 8007, 8124 and Xin 4070, 4079 and Zhong 1001 were breeded.
