摘要
水稻是我国主要粮食作物之一,整个生长阶段对水分的需求远远大于其它作物。然而随着极端气候以及水资源短缺的影响,干旱已经成为造成农作物产量损失最大的非生物胁迫。全面详细地了解水稻抗旱研究相关内容,有助于抗旱水稻品种的培育。本综述从水稻抗旱筛选方法、筛选指标、干旱胁迫条件下产量及其产量相关性状QTL发掘以及抗旱基因的克隆和应用进行论述,并对水稻抗旱品种的培育进行展望。
Rice is one of the main food crops in China. Demand for water in the whole growth stage of rice is far greater than that of other crops. But with extreme weather and the impact of the shortage of water resources, the losses caused by drought on crops are the highest among all abiotic stresses. This article summarized the screening method and index of drought tolerance, QTL mining of yield and yield related traits under drought stress, and cloning and application of drought tolerance genes. Meanwhile, it also put forward the rice breeding for drought tolerance. Comprehensive and detailed understanding of rice drought tolerance would help to breed rice varieties with drought tolerance.
