摘要
本实验利用不同剂量的氮离子束注入优良谷子新品种晋谷28号干种子,并与γ射线处理作比较,研究其诱变效应,并以期获得优良变异株。形态学调查结果显示,氮离子注入与γ射线这两种方法均可诱发株高、穗长、穗型等各种农艺性状发生突变,但两种诱变方法的诱变效应存在差异,氮离子束诱发矮秆、早熟等有益性状突变的频率较大,而γ射线辐照诱发的高秆突变频率较大,结果证明等体离子束诱变技术不仅可以促使种子变异,获得穗长、穗型等有益突变体,而且获得的这些变异在后代中是可以遗传的。
After implanting N^＋ ions of various doses to Millet JinGu28 dry seeds γ comparing to ^60Co γ-rays , the mutagenic （in M1＆M2） effects were studied. The result of morphology showed that two methods could induce variation of the morphology, however, the frequency of the useful mutation induced by implantation of N＋ ions were higher than that induced by y-rays. These results suggested the implanting of N^＋ ions may be useful for breeders to utilize genetically diverse introductions in Millet improvement, and these traits induced by N^＋ ion implantation can be inherited.
