| 摘 要： | 讨论了粳型水稻光敏核不育系93—926s的育性转换特点及育性转换期,证明93—926s是以光敏为主的不育系,育性转换明显,在天津地区,其不育期在8月初到8月底,育性转换期在8月30日左右,其育性转换临界日照长度为13～14h,临界日平均温度为23.0～24.0℃。

Study on Characteristics and the Period of Fertility Alteration of Japonica Rice Photo-Sensitive Genic Male Sterile Line 93-926s |

| Abstract: | This paper has discussed characteristics and the period of fertility alteration of japonica rice photo sensitive genic male sterile line 93-926s.We have found that the fertility alteration of 93-926s is mainly controlled by photo period,and it has distinct characteristics of fertility alteration.In Tianjin area,its sterile period is from the beginning of August to the end of the August.The fertility alteration period is about at the end of August.Critical daily mean temperature inducing fertility alteration is about 23～24 ℃,Critical daylight length inducing fertility alteration is about 13～14 hours. |
