摘　　要：水稻是中国重要粮食作物之一,抽穗期直接决定一个品种的地域适应性和季节适应性,水稻抽穗期与品质和产量等农艺性状极其相关。探讨如何利用常规技术和分子育种相结合的方法,来改变和调控水稻抽穗期,对水稻生产的发展具有十分重要的意义。本研究首先介绍了水稻抽穗期组成要素和遗传特性,总结了鉴定的抽穗期QTL位点,分析了抽穗期相关基因的功能,接着概括了水稻抽穗开花调控网络,最后讨论了当前水稻抽穗期研究中所面临的问题及在生产实践中的应用前景,期望为今后深入开展水稻抽穗期相关研究提供一定的思路和借鉴。Rice is one of the most important food crops in China,and heading date directly determines the geographical and seasonal adaptability of a variety.Heading date is one of the most important agronomic traits closely related to rice yield in rice.Therefore,exploring how to combine conventional breeding methods with molecular breeding to shorten the growth period of the rice varieties has very important significance for the development of rice production.In this paper,we first introduced the components and genetic characteristics of rice heading stage,summarized heading stage of QTL loci,analyzed gene function of the heading stage,and then summed up the flowering regulation network,finally discussed the facing problems in the research of rice heading stage and its application prospect in the production practice.We wish that this paper would provide a number of information and ideals to the further research of heading date.
