| 摘要: |
| 以18个小麦品种和不同剂量化学杂交剂SQ-1为处理，研究了SQ-1的杀雄效果及不同基因型小麦对SQ-1反应的遗传差异。结果表明，在适宜的SQ-1喷施剂量与时期下，供试品种均能被诱导产生大于95%的雄性不育率。对参试品种而言，适宜时期为Feekes 8.0-Feekes 8.5，适宜剂量为3.0～5.0 kg/hm2,以5.0 kg/hm2效果最好。SQ-1与不同基因型小麦品种不存在明显的互作效应。 |

| Effect of male sterility on different wheat genotype induced by SQ-1 |
|
|
| Abstract: |
| This paper reported the effect of different rate of SQ-1 and reaction of different wheat genotype to SQ-1.The result showed that under the suitable rate and in the proper stage SQ-1 could induce male sterility rate above 95%.For all cultivars in experiment,the proper stage was the formation of anther chamber,the suitable rate was 3.0-5.0 kg/hm2,but the rate of male sterility at dosage of 5.0 kg/hm2 was the higher than that at dosage of 3.0 kg/hm2.No interaction was found between SQ-1 and different wheat genotypes.SQ-1 is the best CHA for hybrid wheat seed production. |
