| 摘 要： | 采用携带有隐性核不育基因，不育率为１００％、不育度为９５％的谷子高度雄性不育系与优良恢复系品种测配，根据育种目标，选择优良的杂种Ｆ１继续种植，从Ｆ２育性分离的群体中选择优良不育株，利用其不育基因改谷子自花授粉为异花授粉，进行谷子品种间复合杂交及不同轮回选择群体育种，选育出６个品种和一批具有优异特性的不同世代材料。

| Abstract: | A highly nuclear-male-sterile line of foxtail millet with recessive nuclear sterile gene,100% of the sterility percentage and 95% of sterility degree rate was crossed with a superior restoner line for breeding a hybrid strain.A good-quality F1 of the hybrid was selected to sow,according to the breeding objective.After selecting the superior sterile plants from the F2 fertility segregating population the composite-crossing among the foxtail millet varieties and rotational selecting population breeding were conducted using the sterile gene to alter the self-pollination into allogamy-pollination.Six varieties and a series of variant generation materials with favourable characters were bred. |
