Abstract：A trial of sowing by different stages was carried out with rice“Peiai64S”as control in order to analyze fertility and characteristics of photo-thermo sensitive genic sterile male rice line“Fulong S2”. The results showed that sowing duration of“Fulong S2”from initial date was 86-89 days. Its steady sterile period appeared since July 20. It had good flowering habit and strong stigma vigor. Its blooming rate before noon reached over 70%. It had high rate of extruded stigma and rate of uni-lateral extruded stigma was higher than that of bilateral. The outcrossing seed-setting rate of“Fulong S2”was higher than that of“Peiai64S”.
