摘要 干旱是影响玉米产量的最重要的非生物胁迫因子之一。近年来,随着分子标记技术和数量性状统计分析方法的改进,对调控耐旱等复杂数量性状的位点进行作图和定位方面的研究很多。本文综述了玉米在耐旱QTL(Quantitative trait locus)定位研究领域所采用的耐旱鉴定指标以及耐旱相关性状的QTL定位研究进展,并对目前在QTL定位研究中存在的问题及发展前景进行了探讨。 Drought stress is the first constraint affecting maize （Zea mays L.） production remarkably in the world. In the past decades, with the development of molecular marker technology and quantitative statistical methods, a large number of papers had reported much about mapping and location of complex quantitative traits, such as drought tolerance. The evaluation standards for drought-tolerance of gerrnplasm and QTL（Quantitative trait loci） mapping on maize chromosomes were summarized. Furthermore, problems and prospects of QTL mapping were discussed in this review. It would benefit researches involving in QTL mapping and breeding for drought tolerance in maize.
