摘要
在我省生态条件下,以陕2A胞质不育类型的材料进行三系杂交油菜秋播制种,因初花阶段气温较低母本微量花粉发生较多,其不育株率平均高达76.9%;而改用春播制种相对延迟开花期,开花时母本没有微粉产生,其不育株率仅7.9~12.5%。
In the ecological condition of Guizhou,using Shah 2A CMS carries on ternary bybrid rape seed production in autumnseeding,because of low temperaure in first flowering phase the female parent plant grows small pollen constantly and sterileplant percentage averages 76.9%.But in spring seeding the flowering period can be defered and the small pollen will not beappeared,and sterile plant percentage is only 7.9—12.5%.
