| 摘 要： | 由于雨量不均，目前全球多数地方正面临着严峻的干旱问题。水稻作为三大作物之一，而且需水量特别大，因此摆在水稻面前的干旱问题尤为突出。简要分析了广西的水稻旱害情况，除了保证水利灌溉，提倡节水农业之外，进行抗旱的水稻育种是一个非常有效的办法。水稻抗旱性的有关机理及其现阶段水稻的抗旱育种工作做了一个简要的论述。 |

| Abstract: | Most areas of the world frequently experience severe water deficit due to uncertain and uneven rainfall distribution patterns. The paddy rice as one of main crops (rice, wheat, maize etc.) requires more water than other crops, which is very important especially encountering the drought. The drought disaster of rice was elucidated in Guangxi, China. There is an effective method that developing rice breeding for drought resistance in addition to rational irrigation and Water-Saving Agriculture. The paper shows the mechanisms relevant to rice for tolerance to drought and some work about drought breeding in rice at present. |
