杂交是芝麻育种的重要手段之一。芝麻同一花器中的雌蕊比雄蕊早一天左右成熟。一天中以上午7—8时开花最多,此时开花的花粉生命力最强。但在正常自然条件下,花粉粒的寿命只有3、4小时。因此杂交工作时间只能局限在每天上午6—9时,工作条件很受限制。 我所于1979年至年至1981年的三年杂交实践中,摸索出用胶水封闭父本花冠的胶粘法。采用此法后,可以延长父本花粉的使用寿命。避免昆虫污染花粉,提高杂交工作效率和改善工作条件。 Crossbreeding is one of the important means of sesame breeding. The same flower in the sesame pistil than the stamens mature about a day earlier. One day in the morning at 7-8 when the most flowering, pollen flowering at this time the strongest vitality. However, under normal natural conditions, pollen grains have a lifespan of only 3,4 hours. Therefore, the working hours of hybridization can only be limited to 6-9 am every day, and working conditions are very limited. In my three-year hybrid practice from 1979 to 1981, I worked out the glue method of sealing the male parental corona with glue. Using this method, you can extend the service life of male pollen. Avoid insect pollination, improve hybrid efficiency and improve working conditions.
