1971年,Rowell和Miller首次报导应用乙烯利（Ethrel）诱导小麦雄性不育获得成功,使人们对于采用化学药剂诱导小麦雄性不育以配制杂种,从而利用杂交优势,较大幅度地提高小麦产量的设想得到证实。我国相继于1972年开始了这项研究工作。十余年来,国内外学者对乙烯利诱导小麦雄性不育的技术和机理做了大量的试验与研究,对应用乙烯利诱导小麦雄性不育配制杂种小麦的效果给予了肯定的评价。据我国浙江、山东、北京等地学者的研究认为,采用目前国产40％的乙烯利水剂,以2—氯乙基磷酸有效含量4000～6000ppm的浓度,在花粉母细胞形成至减数分裂期进行一次喷雾,可获得良好的杀雄效果和较高的自由授粉结实率。但不同小麦品种对乙烯利的敏感程度存在一定差异。本研究的目的是要观察几个
In 1971, Rowell and Miller for the first time reported that the successful application of Ethrel to induce male sterility of wheat caused the use of chemicals to induce male sterility of wheat to formulate hybrids, thereby taking advantage of hybrid vigor and greatly increasing the yield of wheat The idea is confirmed. Our country started this research one after another in 1972. More than ten years, domestic and foreign scholars have done a lot of experiments and studies on the technology and mechanism of ethephon-induced male sterility in wheat, and affirmed the application of ethephon to induce wheat male sterility. According to China’s Zhejiang, Shandong, Beijing and other scholars believe that the use of the current domestic 40% of the ethylene diagenesis agent, the effective concentration of 2-chloroethyl phosphoric acid 4000 ~ 6000ppm concentration in pollen mother cells to the formation of meiosis phase A spray, get a good kill male effect and high free pollination rate. However, the sensitivity of different wheat varieties to ethephon is different. The purpose of this study is to observe a few
