摘　　要：通过分期播种和人工控制光温试验,研究了龙特浦A的育性稳定性。结果表明:在湛江自然播期条件下,龙特浦A黑染花粉率较高且波动幅度较大,自交结实率低且波动小,稳定不结实天数达69 d,可安全繁殖制种。温度是引起龙特浦A育性变化的主要原因,光照时数和光温互作对其育性影响不显著。In order to study the fertility stability of rice -Longtepu A in Zhanjang, it was observed trader controlled condition and natural condition in different sewing dates in 2005 ～ 2006. The results showed that： Longtepu A,which had a continue stable sterile period（69 d） and could be safely used for hybrid seeds production,had higher dyed-pollen rates that fluctuated widely than self-seed rates in natural condition in Zhanjang. The effect of photoperied and photoperied × texture interaction was non-significant,while temperature was the main factor of fertility transition.
