- 摘要:
- 不同地区大豆杂交方法不尽相同，结合黑河市高纬寒地地区大豆多年杂交经验，介绍了一种适合高纬寒地大豆杂交的方法。具体杂交方法为：一般在母本盛花期的当日4∶00选择大花蕾没散粉前去雄，5∶00左右选择中、小花蕾去雄，8∶00以后花粉极佳时进行授粉。先去雄后授粉的方法有利于大豆的雌蕊发育，可提高杂交成活率。适当选择母本大花集中去雄，间隔一段时间后集中授粉，既提高了成活率，又可避免伪杂种。
- Abstract:
- Soybean hybrid method should be modified slightly according to different ecological areas.Combining of Heihe high latitude cold region soybean hybrid experience for many years,a soybean hybrid method suitable for high latitude cold was introduced.Specific hybridization method was:at the 4:00 AM choose and emasculate large flower bud before maternal parent powder,at 5∶00 AM choose and emasculate medium and small flower bud,after 8∶00 AM pollinate when pollen is admirable. This hybrid method could promote the growth of the pistil and improve the survival rate of hybridization.This research established efficient soybean hybrid method and provided the technical support for soybean genetic breeding.
