本文通过分析反向光温敏Ｓ系Ｈ─３＿ｓ、南４３＿ｓ在连云港（Ｎ３５°）、沈阳（Ｎ４２°）的育性表现，确定Ｈ─３＿ｓ的育性转换可结实温度为２７℃左右，育性转换敏感期为抽穗前１５天左右，育性转换与光周期无关或关系不明显。结合连云港及沈阳等北方地带的气象特点，提出了Ｈ─３＿ｓ的应用前景，认为它在沈阳以北及云贵低纬度、高海拔地带将同正向光温敏不育系一样，同样具有利用和转育价值。
In this paper, the fertility of H-3_s fertility was determined by analyzing the fertility of S-H-3_s and S-43s in Lianyungang (N35 °) and Shenyang (N42 °) The sensitive period of sexual transformation is about 15 days before heading, fertility transformation has nothing to do with the photoperiod or the relationship is not obvious. Combined with the meteorological characteristics of the northern areas such as Lianyungang and Shenyang, the application prospect of H-3_s is proposed. It is believed that it will have the same potential as the positive photo-thermo-sensitive genic male sterile lines in the low latitudes north of Shenyang and Yunnan-Guizhou, Transferable value.
