摘要： 抗旱性水稻材料的鉴定筛选是培育抗旱性水稻的一个重要方面。概述了国内外评定水稻抗旱性的常用鉴定方法与评价指标，综合分析了各研究方法的优劣性。并根据前人们对各种抗旱性指标的研究结果，指出了使用单一的抗旱性评价指标的局限性，应构建形态、生理、生化等方面筛选的综合性指标体系来正确评价水稻的抗旱性。

Abstract: Materials Identification and Screening of drought resistance in rice is an important aspect to cultivate rice variety of drought resistance. In this paper, identification methods and evaluation indicators used by assessment of drought resistance of rice at home and abroad were provided, and the pros and cons of various research methods were comprehensive analyzed. Besides, the limitations of using a single drought evaluation indicator was pointed out, and a comprehensive index system include morphological, physiological and biochemical should be built to correctly evaluate the drought resistance of rice.
