| 摘 要： | 为了明确化学杂交剂SQ-1对四川小麦雄性不育的诱导作用,以20个四川小麦品种(系)为研究对象,研究SQ-1不同喷药时期对不同基因型小麦的杀雄效果.结果表明,Feeks 8.5为四川小麦最佳喷施时期;适宜的喷施时期为Feeks 8.0～9.0.用4.0 kg/ha的SQ-1进行雄性不育的诱导,所有供试品种平均可达到97.09%的相对雄性不育率和49.77%的异交结实率.喷施SQ-1后,四川小麦的株高明显降低,抽穗推迟并且穗长缩短.另外,基因型的不同导致化杀效果及化杀后农艺性状有差异.

| Abstract: | To study the effect on male sterility and agronomic traits between different genotypes of wheat induced by CHA SQ-1,the experiment was conducted with 20 Sichuan wheat varieties(lines) and SQ-1 spraying at different stages.The result showed that Feeks 8.5 was the best spraying stage.Spraying 4.0 kg/ha SQ-1 during the stage Feeks 8.0~9.0,the average male sterility rate was 97.09% and the pollinated seed set rate was 49.77%.The result also showed that SQ-1 could reduce the plant height,postpone the heading dat... |
