摘要
用^(60)Co-γ射线诱导小麦T型雄性不育系T小偃4号A、T郑引1号A均获得了农艺性状优良、恢复力强的恢复系。育性恢复突变是涉及一个或少数几个位点核基因的显性突变。利用性状优良的T型不育系诱导育性恢复突变是选育恢复系和发掘恢复源的有效途径。
Restorer lines with excellent agronomic characteristics and high restorability were gained by using 60Co-y ray induction from male-sterile lines in T.timopheevi cytoplasm of T-Xiaoyan No.4A and T-Zhengyin No.1A.Fertility restorer mutation was a kind of dominant mutation involving one or more loci of nucleus genes.Using the male sterile lines in T.timopheevi cytoplasm with fine characteristics to induce fertility restorer mutation is an effective approach to select and breed restorer lines and exploit restorer resources.
