水稻恢复系航天育种的研究

Study on Space Breeding of Restoring Line of Rice

通过航天育种途径对中稻恢复系明恢63、838、752等进行改良,选育出航98、SP90010、SP134、SP143等强优恢复系,并与不育系配组育成了SP优Ⅰ98、丰优航98、中九优10、G4优10等高产、优质、抗性强的杂交组合。

The middle rice restoring lines Minghui 63,838 and 752 were improved by space breeding, and strong and excellent restoring lines Hang 98, SP90010, SP134 and SP143 were bred. Through crossing between above restoring lines and various sterile lines, several combinations with high yield, high quality and strong resistance such as SP You I98, Fengyouhang 98, Zhongjiuyou 10 and G4 You 10 have been bred.
