摘 要：
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（单核期）的不育株率可达８１％。在五叶期至造孢细胞期施药３～４ｄ后，出现叶片坏死斑，植株明显变矮或部分株死亡等药害现象，不育花粉率只有２％～４％。在花粉母细胞减数分裂期至成熟花粉期喷药处理，花药的绒毡层及花粉均出现异常，不育花粉率可达１７％～８０％。

摘 要：
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 partial dead plant and so on,which sterility pollen rate was 2%～4%. From pollen mother cell meiotic division stage to pollen stage,the tapetum of anther and pollen all showed abnormal phenomenon,which sterility pollen rate was about 17%～80%.
