摘　　要：玉米是一种非常重要的粮食作物和经济作物,在玉米生产中,主要应用的是杂交种,而雄性不育因其自身的优势逐渐成为杂交制种应用的趋势。近几十年来,科研人员在对玉米细胞核雄性不育突变体的研究进行了持续不懈的努力,对雄性不育基因进行定位、克隆及功能研究,目前已经有不育基因被克隆出来。本文主要对玉米细胞核雄性不育基因定位克隆和功能等进行了综述,并简要的介绍近些年比较常用的基因定位技术以及涉及到的分子标记。Maize is a very important food crop and economic crop. In corn production, the main application is hybrids, and male sterility has gradually become the trend of hybrid seed production due to its own advantages. In recent decades, researchers have made unremitting efforts to study the male sterility mutants of maize nuclear nucleus, and have located, cloned and functionally studied male sterility genes. At present, sterility genes have been cloned. This article mainly reviews the location, cloning and function of maize nuclear male sterility genes, and briefly introduces the more commonly used gene mapping technology and the molecular markers involved in recent years.
