摘　　要：大豆是世界重要的粮油兼用作物,也是人类优质蛋白及畜牧业饲料蛋白的主要来源。大豆是喜磷作物,磷不仅是大豆遗传物质的重要组成成分,同时参与大豆体内酶促、新陈代谢、根瘤固氮等生理生化过程。全世界耕地中近1/2的耕地处于缺磷状态,我国耕地中大约有2/3的耕地属于缺磷状态,磷胁迫是限制大豆产量最主要的因素之一。文章分别从低磷胁迫下大豆形态学变化以及大豆生理生化反应、遗传图谱的构建及大豆耐低磷QTL定位研究进展进行了初步概述,并对大豆耐低磷QTL定位进行了展望,以期为我国大豆耐低磷遗传育种研究提供参考。Soybean is an important grain and oil crop in the world, and it is also the main source of high quality protein and animal feed protein. Soybean is one of the P-loving crops. Phosphorus is not only an important component of soybean genetic material, but also participates in physiological and biochemical processes such as enzymatic metabolism, metabolism, nodule nitrogen fixation and so on. Nearly one-half of the world＇s arable land is in the state of phosphorus deficiency, and about twothirds of the cultivated land in China is in phosphorus deficiency. Phosphorus stress is one of the most important factors limiting soybean yield. In this paper, the morphological changes, the physiological and biochemical responses of soybean, the construction of genetic map and the QTL mapping of soybean tolerance to low phosphorus were reviewed. The QTL mapping of soybean tolerance to low phosphorus was prospected, which would provide theoretic basis for improving the research advance on genetics and breeding of tolerance to low phosphorus stress.
