特优5565亲本生育特性初步观察

摘要

Leaf growth rate,heading dynamics and flowering habits of the parents of Teyou 5565,i.e.Zhanghui 5565 and Longtepu A were observed.The results showed that their leaf growth rates were similar,and their peak periods of flowering time was both obvious.Therefore,Teyou5565 will obtain high and stable yield in hybrid seed production by synchronization of flowering and anthesis owing to reasonable arrangement of seeding time.%试验对特优5565亲本漳恢5565与龙特浦A出叶速度、抽穗动态及开花习性进行观察,结果表明：父母本的出叶速度趋势相似,父母本都有较为明显的抽穗高峰期,合理安排播差期,可以很好地保证花期相遇,为特优5565制种获得高产奠定基础。
