| 摘 要： | 9403是国内新合成的一种哒嗪类化合物，经初步研究证明，9403具有诱导小麦雄性不育的作用。试验以GENESIS化学杂交剂为对照，对9403诱导小麦雄性不育的作用进行了研究。结果表明；9403对试验的两个品种西农6419与BAU95在其花药发育的药隔期，用剂量0.75kg/hm^2进行一次叶面喷施，诱导雄性不育率可达到96%以上，人工饱和授粉证明9403对雌蕊的育性没有影响，平均人工饱和授粉结实率为88.6%，与GENESIS相比，9403的杀雄效果较不彻底且具有一定的药害。 |

| Abstract: | is a nwe pyridazine compound.In this paper 9403 had been evaluated as a chemical hybridizing agent(CHA) for two wheat cultivars BAU95 and Xinong6419.The results showed that:In the rate of 0.75 kg/hm 2,with application active window at formation of anther chamber,9403 could induce male sterility rate above 96.0% for two cultivars.The pistil and crossfertility in the handed pollination were normal.The average handed pollination rates were 86.8% and 98.0% for BAU95 and Xinong6419 respectively.Compared with GENESIS and untreated controls,There were some side effects showed on plant development and plant growth. |
| Keywords: | wheat CHA 9403 male sterility |
