采用不同浓度的化学杂交剂ＫＭＳ－１处理不同生长发育时期的油菜，诱导其雄性不育，结果表明：在试验的ＫＭＳ－１浓度范围内，最佳杀雄浓度为１．５％，最佳处理期朱育株率可达８１％。在五叶期至造孢细胞期施药３－４ｄ后出现叶片坏死斑，植株明显变矮分析不死亡等药害现象，不育花粉率只有２％－４％。

The rapeseed at different development stages were treated by different concentration chemical hybridization KMS—1 and male sterility was induced.The results showed that the most effective concentration of KMS—1 was 1.5% in treatment concentration range and the best stage was uninucleate stage,which should be given sterility plants rate was about 80%. From five leaves stage to sporogenic cell stage treated with KMS—1 after 3～4 days,the plant shown some medical harm,yellow patch in leaves and the plant height apparently became short and parti...
