Abstract: The author of this paper has engaged in the studying of distant cross breeding for thirty years during which forty times of hybriding have been done (ten of which in other district). This paper have introduced the natures of Agropyron glaucum; the technique of distant cross; the methods to overcome the sterility of distant hybrids; and the selection of the octoploid species, the alien addition lines as well as the new high-yielding common wheat with resistance to diseases. Through study some genetical questions, which are worth researching further, are put forward.

Key words: Wheat, Agropyron, Distant cross
