- 摘要:
- 1998 和1999 年夏选用51 份大豆材料对NJCMS1A 进行测验性交配。在花期治虫预防昆虫传粉的基础上, 通过成熟期的植株结实性辅以花粉发芽试验来判断F1 雄性育性的恢复性。在此基础上初步筛选出了NJCMS1A 的恢复源21 个以及保持源17 个, 其中不育细胞质的提供者N8855是不育系的恢复源。
- Abstract:
- Fif ty -one soybean genotypes w ere crossed wi th NJCMS1A in the summers of 1998 and 1999 .Through spraying insecticide during blooming period to avoid insect -mediated pollination , the male fertility ofF1 plants was observed according to the pod -set ting situation at maturi ty supplemented w ith pollen germinat iontest .The 21 resto rers and 17 maintainers of NJCMS1A w ere screened out of the above fif ty -one genotypes.N8855 , w hich w as the donor of male -sterile cy toplasm of NJCMS1A , w as also a restorer of NJCMS1A .
