Wild relatives of wheat in Triticeae have contained a great number of such valuable genes as resistant genes and so on, the introduction of alien genetic germplasm from related species was an important method for improving genetic base of wheat. In order to reach the target, wheat line A42912 with high yield characters, and rye inbred line R3 derived from Weiyuan area in China,were used as parents, alien germplasm of the progenies from wheat-rye hybrids was studied in the present paper. Results were shown a...
