摘要： 为了扩大水稻抗旱资源的应用，提高水稻抗旱育种效率，对来自17个不同国家105份水（陆）稻品种（系）进行干旱胁迫效应评价。采用了同异分析法，在干旱胁迫下，株高、单株有效穗、穗长、每穗实粒数、每穗总粒数、结实率、千粒重、单株谷重8项农艺及经济性状，进行了综合评价分析。结果表明：105份水（陆）稻品种（系），分析评语“差”的有60个品种，占57.1%；“一般”的评语共有22个品种，占21%；“较好”和“好”的评语各有10个品种，占9.5%；“优良”的只有4个品种，占3.8%,分别为IR77298-14-1-2-13、IR77298-5-6-18、CACHO PRETO、IR77298-5-6-11，均为籼稻品种。由此得出，籼稻品种抗旱性明显高于粳稻品种，抗旱同异评语的级别与每穗实粒数、结实率、单株谷重3个性状密切相关。

Abstract: In order to expand the application of rice-drought-resources, and improve rice-drought-resistance breeding efficiency, this paper was comprehensive evaluation analysis of 105 materials, which paddy (upland) rice from 17 different countries. Under drought stress by identical-discrepant analysis method, 8 agronomic which were plant height, panicles, panicle length, grains per panicle, each spike total grains, seed rate, grain weigh and grain weight per plant, and economic traits referred to a comprehensive evaluation and analysis. The results showed that there were 60 “poor” varieties, accounting for 57.1%; 22 “general” varieties, accounting for 21%; 10 “better” and “good” varieties, each accounting for 9.5%; “choiceness” only 4 varieties, accounting for 3.8%, such as, IR77298-14-1-2-13, IR77298-5-6-18, CACHO PRETO, IR77298-5-6-11, all varieties were indica rice. Indica rice varieties of drought resistance were significantly higher than japonica rice varieties, identical-discrepant comment with different levels of drought was closely related to 3 traits, which were grains per panicle, seed setting rate and grain weight per plant.
