Fossati 和 Ingold(1970)通过辐射(24kR)从瑞士小麦品种 Probus 中分离出单因子的雄性不育突变体(mslb)。F_1单体分析表明不育基因位于4 A 染色体上。Pugsley 和 Cornerstone 突变体的染色体雄性不育基因也位于4 A 染色体上。Pugsley与 Probus、Cornerstone 与 Probus 的雄性不育基因是等位的。Probus 和 Cornerstone 的雄性不育基因被认为是末端缺失与着丝点独立造成的。Popov(1974)论述过在小麦育种计划中利用遗传的雄性不育的问题,旨在建立一个以
Fossati and Ingold (1970) isolated one-factor male sterile mutant (mslb) from the Swiss wheat variety Probus by irradiation (24 kR). F_1 monomer analysis showed that the sterile gene is located on the 4 A chromosome. The chromosomal male sterility genes of the Pugsley and Cornerstone mutants are also located on the 4 A chromosome. The male sterility genes of Pugsley and Probus, Cornerstone and Probus are allelic. The male sterility genes of Probus and Cornerstone are thought to be caused by the absence of the terminal end and the independence of the centromere. Popov (1974) discusses the use of genetic male sterility in wheat breeding programs to establish a
