研究提高突变率和扩大变异谱,对提高花生辐射育种效果是极为重要的,国内外对此项工作已做了不少的研究。当前比较普遍肯定的是用γ射线2—3万伦琴照射花生干种子效果较好,但干种子照射后不同贮藏时间对其突变效应的影响如何?报导尚少,为此,我们用钴60γ射线作了这方面的研究,探讨其诱变效果,以求筛选出较优的照射处理。 Research to improve the mutation rate and to expand the mutation spectrum is very important to improve the radiation breeding effect of peanut. Many researches have been done on this task at home and abroad. At present, it is generally accepted that irradiation of dried seeds with 2-3,000 Roentgens with γ rays is better, but the effect of different storage time on the mutation effect after dry seeds irradiation is still poor. For this reason, we use cobalt 60γ ray Made a study in this area, to explore its mutagenic effect in order to screen out a better irradiation treatment.
