杂交小麦混合制种新体系的初步研究

Study on New System of Producing Hybrid Wheat Seed by Mixing Male Sterile Line and Restorer Line

将不育系和恢复系按不同比例混合,生产杂交小麦F1代种子。对混合制种条件下不育系的结实率和不育系、恢复系、杂种F1代的株高、抽穗期、开花期以及杂交种的产量构成的调查结果表明,不育系和恢复系按17:3比例混合,其制种结实率及混收种（包含杂交种和恢复系）的产量都明显优于对照。

The seed of male sterile line and its restorer line were mixed in different proportion. By investigating the seed setting, plant height, heading date, flowering data of sterile line and restorer lines and hybrid, and the yield components of hybrid, the result showed that it had a better productive potentiality, and when the plants of male sterile line and restorer lines mixed in 17 : 3 ratio, its seed setting on female and the yield of hybrid mixture were better than CK.
