Abstract: The fertile F_1 hybrids(2n=21)between Triticum carthlicum Nevski var.darginicum(AABB)and various accessions of Aegilops tauschii Cosson(DD)had theseed-set ranging from 21.25 to 39.72 percent.Cytological observations showed thatthere were two mechanisms on the formation of unreduced gametes which rel
