摘要
繁源A具有开花习性好、花时集中,异交率高等特点。依据近几年的观察,总结其高产繁殖技术主要有以下几点:选择具有天然屏障条件的隔离基地;选择适宜的抽穗扬花期天气条件:大气温度28~32%,大气相对湿度70%~80%;灌浆成熟期保持田间湿润,利于籽粒灌浆饱满和减少裂颖。
Fanyuan A, a new indica three-line WA-type CMS line have the characteristics of good flowering habits, outstanding flowering time, high out-crossing rate, etc. Through observation of its characteristics for some years, we conclude that there are three kinds of conditions to form its high-yield seed multiplication: seed multiplicative region, the weather and the water management.
