在小麦雄性不育的研究工作中,选用什么品种作保持系、恢复系方面,中国科学院遗传研究所根据近几年来的试验,初步摸索到以下几点经验,可供进一步研究时参考。 1.宜选择矮秆或中等的品种做保持系(新不育系的父本),选择秆较高的品种做恢复系。换句话说,不育系要秆矮点,恢复系要秆高点,以便后者给前者传粉,并能使所获杂种 In wheat male sterility research work, what kind of varieties to choose as the maintainer and restorers, the Institute of Genetics, Chinese Academy of Sciences according to the tests in recent years, initially explored the following points of experience for further study reference. 1. Should choose to do dwarf or medium varieties to maintain line (new male sterile line), choose to cultivate higher varieties of restorer line. In other words, the CMS lines need short stalks to restore stem height to the latter so that the latter pollinates the former and allows the hybrids
