| 中文摘要: |
| 籼粳交育种是水稻育种取得突破的基本途径，以培育掺粳籼稻为主题，分析了籼粳交育种的多个育种策略，利用典型粳稻和采用三交（回交）方式是优先可取的方法，但存在工作量大的问题。 为此，提出了工作量小、能有效缩短育种时间的高效育种策略，即（籼型细胞质雄性不育系/对细胞质雄性不育系具有保持能力的典型粳稻品种 F1//具有恢复能力的籼稻品种或恢复系” 的育种策略， 回顾了籼粳交育种历程及所取得的成效，并对籼粳交育种策略的进一步优化进行展望。 |
| 英文摘要: |
| Indica/japonica rice cross breeding is a basic approach to achieve breakthrough in rice breeding. As the subject to develop indica rice introgression by japonica rice, various breeding strategies of indica/japonica rice cross were analyzed. The use of typical japonica rice and adoption of three-way cross (backcross) were preferential method with labor-consumed. To solve the problem, Indica CMS line/typical japonica rice with maintaining ability// indica rice with restoring ability, a strategy which can shorten the duration of breeding with little workload, was put forward. The course of the breeding and the achievements were reviewed and prospect of breeding was viewed. |
