摘　　要：高粱的雄性不育有多种类型,发生的原因复杂。对高粱雄性不育机理的探索一直是高粱杂种优势研究的重要领域。近年来采用细胞学和分子生物学方法对高粱雄性不育的研究取得了一些新的成果,从绒毡层细胞结构与功能的分析、减数分裂以及ATP酶的分布特征、不同的细胞生物学研究角度探索了雄性不育花药的败育过程。这些研究进展不仅对探明高粱雄性不育机理、恢复机制等有重要价值,而且对促进高粱杂种优势利用研究有重要意义。本文着重从细胞学水平介绍有关高粱花药败育过程的研究进展。There are many tapes of male sterility in sorghum. The cause of the CMS are complicated. Some new results of sorghum CMS have been made by cytology and molecular biology in recent years. The male sterile anther abortion has been explored on the tapetal cell structure and function, meiosis, as well as the distribution of ATPases. Those sdudies not only detected the mechanisms of sorghum CMS and restore but also promoted the utilization of sorghum heterosis. This paper is concentrated on cytology to introduce the progress of the sorghum anther abortion process.
