摘　　要：为了研究化学杀雄剂SQ-1对青海高原春麦区的杀雄效果及不同春小麦品种对SQ-1反应的遗传差异，采用时期为主区、剂量为副区、小麦品种为亚副区的三因素裂区设计方法，对化学杀雄剂SQ-1诱导青海高原春小麦雄性不育的效果进行了研究。结果表明，在Feekes8．0-Feekes8．5时期，5．0kg／hm^2剂量下，参试品种均能被诱导产生大于95％的雄性不育率。对参试品种进行人工饱和授粉，其结实率均能达到90％以上，证明sQ-1对雌蕊无明显影响。To study the effect of male sterility of spring wheat in qinghai plateau induced by SQ-1 and the reaction between different cultivars, the three factors split plot design experiment including main plot, split-plot pose and the variety split-split plot. The results showed that all cuhivars in experiment could be induced male sterility rate above 95% at the stage of feekes 8.0 - feekes 8.5 under 5.0 kg/hm^2. The pistil fertility could up to 90% in the supplementary pollination,it indicated that SQ-1 had no obvious effect on pistil.
