我省涿鹿县温泉屯大队于1974年用普通小麦品种“伊拉克71—28”做母本与普通小麦品种“科1105”杂交,F_1代得到半不育株,经分离选择、回交转育培育成功了具有“伊拉克71—28”细胞质的“伊1105”雄性不育系。几年来在云南昆明、广东海南岛、河北涿鹿等不同气候环境条件下,不育性均表现稳定。中国科学院遗传研究所和山东省昌潍地区农科所重复试验,都得到同样结果。经中国科 The Wenquan Village Brigade in Zhuolu County of Fujian Province crossed the common wheat variety “Iraq 110” with the common wheat variety “Iraqi 71-28” in 1974 and the F 1 generation gave the semi-sterile line. After selection and selection, The “Yi 1105” male sterile line with the “cytoplasm of Iraq 71-28” was successfully cultivated. Over the past few years in Kunming, Yunnan, Hainan Island, Hebei Zhuolu and other climate conditions, the sterility are stable. Chinese Academy of Sciences Institute of Genetics and Changwei, Shandong Province, repeated trials of agricultural, have been the same result. By China Branch
