1982年,我们作了钻60-γ射线、快中子对玉米诱变(M_1)效应研究(见《广西农业科学》1983年第4期)之后,对其后代M_2、M_3代继续进行对比观察。 M_2代将M_1代收获的自交果穗种子按处理混合脱粒,单粒点播,幼苗三叶期调查叶绿素突变,成熟期调查株高和矮秆突变株。开花期随机选取一部分植株套袋自交。
In 1982, we made comparative studies on the effects of mutagenesis (M_1) of 60-γ-rays and fast neutrons on maize (see “Guangxi Agricultural Sciences”, No. 4, 1983), and compared their M_2 and M_3 generations . M_2 generations of M_1 generation of self-harvested ear seeds were processed by mixing threshing, single-on-demand seedlings, three-leaf seedling chlorophyll mutation survey, mature plant height and dwarf mutants. Part of the flowering period randomly selected plants bagging self.
