岗22杂稻品种亲本库大源足，具制种高产的基础，分蘖力稍弱，制种要求插足基本苗；岗46A母本花期花时比父本CDR22长，制种母本比父本早始稳1至3天花期相遇理想；亲本开花要求光照足温度高，制种适宜在海拔500m左右或特殊环境条件（热量充足），扬花授粉期日平均温度27℃至29C最适宜，湿度80％左右；岗46A开颖时间长，开花不集中，CDR22开花集中，终花早，在花期相遇条件下，调节花时确保花期花时相遇，提高结实率。
Gang 22 hybrid rice varieties of large source foot base, with a high-yielding basis, weaker tillering ability, seed production requirements to meet the basic seedlings; Kong 46A female anthesis flowering time than the parent CDR22 long, The flowering of the parents required sufficient light temperature, the suitable seed production is about 500m above sea level or special environmental conditions (adequate heat), the average daily temperature of pollination from 27 ℃ to 29C is the most suitable, the humidity is 80% 46A open a long time, flowering is not concentrated, CDR22 flowering concentrated, early flowering in the flowering meet the conditions to ensure that flowering time to meet, to improve the rate of seed setting.
