| 摘 要： | 概述了粳型亲籼系在杂交稻育种中的应用情况,解释并分析了粳型亲籼系能成功育成不育系的原因,提出了利用粳型亲籼系培育掺粳籼型杂交稻的育种策略并分析其育种效率,随着掺粳籼型杂交稻的育种规模扩大,利用粳型亲籼系比直接利用粳稻的育种效率高。

Application ofIndica-compatibleJaponica Line in Hybrid Rice Breeding and Its Reflection |
| |
| Abstract: | The application of indica-compatible japonica line in hybrid rice breeding was resumed. Develop-ing indica-compatible japonica line as A line was reasonable strategy. The application of indica-compatible japonica line to develop indica line introgressed by japonica rice was put forward and its breeding efficiency was analyzed. The application of the line was actually more efficient than that of japonica rice in large-scale indica-japonica crossing breeding. |
