冷水处理对水稻温敏核不育系育性影响的初步研究

Primary Studies on the Effect of Cold Water Irrigation on the Fertility of Thermo-sensitive Genic Male Sterile Lines in Rice

报道了不同临界温度温敏核不育系的育性对冷水处理的反应，证实适当温度的冷水处理具有恢复育性的效果，并讨论了冷水处理。

The responses of fertility of TGMS lines in rice to the cold water irrigation were studied. It was confirmed that the irrigation of cold water with suitable temperature lower than critical values could result in fertility restoration from sterility in TGMS lines. The temperature of cold water, cold tolerance of TGMS lines and application of cold water irrigation were also disscussed.
