以10个小麦品种和化学杂交剂SQ-1为材料,研究了SQ-1的杀雄效果及其不同基因型小麦对SQ-1的反应的遗传差异。结果表明,在参试品种主茎旗叶抽出倒2叶一半,幼穗长为2.5～4.0cm,穗分化期为药隔期喷施4.0kg/hm2的SQ-1,诱导雄性不育率达到了99.93%以上,并经方差分析,材料间无显著差异。说明化学杂交剂SQ-1与参试小麦不同基因型品种不存在明显的互作效应。 Ten different wheat cultivars and SQ-1 were used to study the genetic effects of SQ-1 on the killing effect and SQ-1 response of different wheat genotypes. The results showed that in the main stem of the tested cultivars, the flag leaves of the main stem had half inverted 2 leaves, the spike length was 2.5-4.0 cm, and the spike differentiation stage was 4.0 kg / hm2 of SQ-1, which induced the male sterility rate Over 99.93%, and by variance analysis, no significant difference between the materials. This indicated that there was no obvious interaction effect between SQ-1 and different wheat genotypes.
