摘　　要：在杂交水稻生产中,增加水稻柱头的外露性对于提高水稻不育系的异交结实率以及繁殖、制种产量具有重要的作用.随着分子生物学与遗传学的发展,我们对水稻柱头外露性的调控机制有了更为深入的理解.综述关于水稻柱头外露性的最新研究进展,讨论遗传和环境因素如何影响柱头的外露性,分析这一过程的分子调控机制,并且总结利用分子标记辅助选择的育种策略在改良水稻柱头性状方面的研究进展.通过全面整理这些研究成果,旨在为提高杂交水稻不育系的柱头外露性和异交习性提供理论基础和实践参考.In hybrid rice production, increasing the exposure of rice stigmas plays a crucial role in enhancing the outcrossingseed setting and boosting the yield of breeding and seed production in rice sterile lines. With the continuous progressin molecular biology and genetics, we have gained a deeper understanding of the mechanisms regulating theexposure of the rice stigmas. This study reviews the latest research progress on the exposure of the rice stigmas. Thearticle discusses in detail how genetic and environmental factors affect the stigma exposure, and analyzes themolecular regulation mechanisms of this process, and summarizes the research progress in improving stigma traitsof the rice using breeding strategies of the molecular marker-assisted selection. By comprehensively summarizingthese research findings, this article aims to provide theoretical basis and practical references for improving stigmaexposure and outcrossing habits of male sterile lines in hybrid rice.
