摘　　要：密植是提高大豆单产的重要技术措施之一,大豆耐密植性是大豆品种的基因型与环境共同作用的结果。影响大豆品种耐密植特性的生长性状主要是株型性状和抗倒伏性等,其中株型性状包括株高、分枝数、叶柄长度和叶片大小等。研究人员通过对不同遗传群体进行解析,获得了多个控制相关表型的QTL位点并提出相关的候选基因。迄今在soybase网站中汇集了238个控制株高性状的QTL和68个与株高相关的QTN,21个与分枝相关的QTL,106个与抗倒伏性或茎秆强度相关的QTL位点。本文综述了大豆耐密植性相关性状遗传调控机制研究进展,以促进大豆耐密植遗传调控研究,为耐密植品种的分子设计育种提供参考。High density planting is one of the technical measures to improve the yield of soybean,and the tolerance of soybean varieties to high planting density is the outcome of the interaction between genotype and environment.The growth traits affecting the densely planting tolerance characteristics of soybean varieties were mainly plant architecture,e.g.plant height,branch number,the length and the angle of petiole,and lodging resistance.By analyzing different genetic populations,the reseachers obtained multiple QTL sites that control relevant phenotypes,and propesed relevant candidate genes.Up to now,238 QTL controlling plant height,68 QTN related to plant height,21 QTL related to branch,and 106 QTL related to lodging resistance or stem strength have been collected in soybase.This review briefly summarizing recent progress on genetic factors underlying the tolerance to high planting density will facilitate further fine-mapping and gene cloning of identified novel QTL as well as further functional studies;and will benefit the breeders to breed the tolerant cultivars to high planting density through molecular design breeding.
