水稻抗旱性的研究进展

Research Progress of Drought Resistance of Rice

随着全球水资源的日益匮乏和旱灾的日趋严重,水资源短缺正成为制约我国农业发展的重要因素。培育抗旱栽培稻品种并实现水稻旱种,不但可较大程度地节约水资源,且有利于稳产增产、节约能源和减少环境污染,故栽培稻的抗旱性研究作为稻作科学研究的重要课题显得愈来愈重要。本文从水稻抗旱性鉴定形态指标、生理指标和分子标记研究三方面分别概述,并对今后水稻抗旱性方向进行了探讨。

Along with the increasing scarcity of global water resource and gradual seriousness of drought,water shortage is crucial for restricting agricultural development in China.Breeding rice cultivars with drought resistance and cultivating them in the dry land are helpful not only to save water resource and to steady yield,but also to increase yield,to save energy and to decrease environmental pollution.So studies on drought resistance in rice have become increasingly important proposals of rice scientific researches.This paper reviewed morphological indexes,physiological status and molecular genetic of drought resistance identification in rice.The research direction of drought resistance of rice were also prospected.
