    水稻光温敏核不育系福龙S2的育性观察

    Observation on fertility of photo-thermo sensitive genic sterile male rice line “Fulong S2”

      摘要
    • 摘要: 以培矮64S为对照,采用分期播种试验,分析水稻光温敏核不育系福龙S2的育性与特征特性表现,结果表明:福龙S2播始历期 86~89 d;稳定不育期从7月20日开始;开花习性好,柱头活力强,午前花比率达70%以上;柱头外露率较高,单边外露率高于双边外露率;福龙S2比培矮64S具有更好的异交结实特性。

       

      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 unilateral extruded stigma was higher than that of bilateral. The outcrossing seed-setting rate of “Fulong S2” was higher than that of “Peiai64S”.
