籼稻低温敏核不育系是适合我国南方稻区应用的两用核不育系类型之一,由于其育性转换临界温度较低(23～24℃),在水稻正常生产季节繁殖比较困难,目前普遍采用的繁殖方法是冷水串灌、海南南繁和温室冬繁等技术。1995～1996年冬春季在广州首次利用温室控温技术冬繁培矮64Ｓ获得成功
Indica rice thermo-sensitive genic male sterile line is one of the two types of dual-purpose nuclear sterile lines suitable for rice planting in southern China. Due to its low critical temperature of fertility transformation (23-24 ℃), it is more difficult to propagate rice in normal production season. The current widespread breeding method is cold water string irrigation, Hainan Fanfan and greenhouse winter Fan and other technologies. Winter of 1995 ~ 1996 in Guangzhou for the first time using greenhouse temperature control technology in winter and short Pui 64S success
