摘要: 玉米(Zea mays)是我国种植面积最大和总产量最高的第一大粮食作物, 同时也是杂种优势利用的典范。但与发达国家相比, 我国玉米生产仍然存在着平均单产偏低、突破性品种缺乏和杂交种生产成本高等突出问题。雄性不育系的应用可进一步提高玉米杂种优势的利用效率并最终提高单产。该文综述了玉米雄性不育的分类、基因克隆与机理解析以及分子调控网络构建最新研究进展, 系统介绍了已建立的玉米新型工程核不育技术体系及其应用前景, 为推动玉米雄性发育生物学研究与开展玉米雄性不育杂交育种和制种提供重要参考。

Abstract: Maize (Zea mays) is the major grain crop with the largest planting area and the highest total yield in China, and it is also a model of heterosis utilization. However, compared with developed countries, China is still facing several outstanding problems in maize production, such as low average yield, lack of breakthrough varieties and high cost of hybrid seed production. The main solution to these problems is the application of male-sterile lines with better heterosis utilization efficiency and thus increase the yield per unit area of maize. In this review, we summarize the latest advances of male sterility research in maize, including its classification, gene cloning and functional analysis, molecular regulatory network construction, and discuss the strategies of creating novel male-sterility systems and their potential/future application in maize breeding. This review provides guidelines for the male-sterility based/assisted hybrid breeding and seed production in maize.
