摘　　要：株高作为小麦重要的农艺性状之一,受遗传因子和外部环境共同影响,但遗传因子是最为主要的决定因素。小麦株高性状受到多基因调控,其数量性状位点广泛分布在小麦21条染色体上,目前已开发多个直接应用于育种辅助选择的株高相关的分子标记。目前,国内外学者围绕株高形成的遗传因素、基因定位与克隆、基因调控机理、分子标记辅助育种选择等进行了大量研究,并取得了重要的研究进展。本文综述了小麦株高的构成因素,阐述了小麦株高形成相关基因的遗传定位、克隆及其等位变异的挖掘和在小麦辅助育种中的利用,并展望了小麦株高下一步研究的前景。Plant height is one of the important agronomic traits and controlled by a consequence interacting among the genetic factors,the endogenous hormones and external environment. In common wheat,plant height is recognized as a quantitative trait modulated by multiple genes that are found on 21 chromosomes. Several molecular markers associating with plant height are available for marker-assisted breeding. The important progress on determining the genetic factors,genetic localization and gene isolation,regulation mechanism and marker assisted selection have been achieved. This paper summarizes the factors that contribute to wheat plant height,as well as the achievements on genetic localization,gene cloning,allelic mining,marker-assisted wheat breeding,followed by the prospective on future focuses in wheat.
