摘要
小麦是世界上种植最广泛的作物之一,其株高是优化收获指数、实现粮食产量最大化的重要因素.系统综述了小麦矮秆(reduced height,Rht)基因的分类、多效性特征,以及这些基因功能标记在小麦育种中的应用,讨论了目前已发现的26个与小麦株高密切相关的基因对赤霉素的敏感性及其研究进展,展望了采用各种技术手段挖掘新的矮秆基因的可行性及其在小麦遗传育种中的潜力,以期为提高小麦产量研究提供理论参考.
Abstract
Wheat is one of the most widely grown crops in the world and its plant height is an important factor in optimizing har-vest index and maximize grain yield.This review systematically summarized the classification and pleiotropy characteristics of wheat Rht genes,as well as the application of gene functional markers in wheat breeding.The sensitivity and research progress of 26 genes related to plant height to gibberellins were discussed and the feasibility of exploiting new dwarf genes by various technical means and their potential in wheat genetic breeding were prospected,in order to provide theoretical reference for im-proving wheat yield research.
