用~(66)C_9—γ射线处理扩_(077)、H_(23)、2432为保持系的萝卜质不育系。2432保持的萝卜质不育系半致死剂量约为100k rad,H_(23)、扩_(077)保持的萝卜质不育系半致死剂量约为80k rad。120k rad处理扩_(077)保持的萝卜质不育系M_1,出现了苗期不缺绿的不育株和可育株;120k rad处理H_(22)保持的萝卜质不育系叫,出现了缺绿可育株。100k rad处理扩_(007)保持的萝卜质不育系M_2,出现了19株苗期不缺绿、花器形态与萝卜质不育系一样的不育株。并对这些M_1、M_2的结果进行了讨论。
(077), H_ (23) and 2432 were maintainer lines treated with ~ (66) C_9-γ rays. The semi-lethal dose of radish CMS line 2432 maintained at about 100k rad, H_ (23), d_ (077) was about 80k rad. (077) maintained the radish sterile line M_1, sterile plants and fertile plants that did not lack green at seedling stage appeared; 120k rad treatment H_ (22) maintained the radish quality CMS line, there The lack of green fertile plants. A total of 19 lines of radish CMS lines maintained at 100k rad were expanded, and 19 lines of sterile lines at the seedling stage were observed. The results of these M_1 and M_2 are also discussed.
