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.
