安徽省三系杂交籼稻育种现状与展望

Current Status and Prospects of Threeline Indica Hybrid Rice Breeding in Anhui Province

综述了安徽省２０ａ来三系杂交籼稻的育种成就和存在问题，指出今后的育种目标应主攻早熟、优质、超高产，并选育适于机械化制种和耐旱的组合；技术路线上早杂以选育早熟恢复系，中晚杂以选育优质不育系，亚种间组合以选育广亲和不育系为主。

The achievements and existing problems of indica hybrid rice breeding in Anhui Province in recent twenty years were summarized. It is pointed out that the major breeding objectives should be early maturity, fine quality and super high yield, and the combinations with drought tolerance and suitable for mechanized seed production should be developed. In view of technical approaches the stress of early hybrid rice, medium or late hybrid rice and intersubspecific hybrid rice should be laid on breeding earlymaturing restorer lines, fine grain quality CMS lines and wide compatibility CMS lines, respectively.
