【摘要】 介绍了超级杂交稻恢复系“航1号”的选育过程及其主要农艺学特性,以及用其配制的超级杂交稻新组合“特优航1号”和“Ⅱ优航1号”的稻米品质、区域试验与生产示范结果。利用航天育种技术,“特优航1号”和“Ⅱ优航1号”的稻米品质得到了显著的改良,其蛋白质含量分别为10.7%和10.8%,比对照“Ⅱ优明86”(8.8%)分别提高了1.9和2.0个百分点。更多还原

【Abstract】 The breeding process of the restorer line ‘Hang No.1’ of super-high-yielding hybrid rice carried by spaceflight and its major agronomic characters were discussed. The qualities of rice, the results of the provincial trials and producing paradigm in Fujian Province of the hybrid combinations ‘Teyouhang No.1’ and ‘ⅡYouhang No.1’ were displayed. It was found that the qualities of rice are improved notably of the hybrid combinations ‘Teyouhang No.1’ and ‘ⅡYouhang No.1’. Their protein contents were 10.7% and 10.8% in dry grains, respectively, and 1.9% and 2.0% higher than that of the control, ⅡYouming86 (8.8%).更多还原
