综述了近年来大豆籽粒蛋白质含量分子遗传方面的研究进展。由于遗传因素和环境因素对蛋白质含量均有很大的影响，因此，不同研究者的研究结果差异很大。利用表型数据的传统遗传研究表明，大豆籽粒蛋白质含量以加性效应为主，但不同材料之间遗传力差异很大，在31%～99%之间。在所有20个染色体上均发现有相关的QTL 位点，共有298个 QTL，贡献率介于0.002%～80%之间，其中20号（I 连锁群）、15号（E 连锁群）等染色体上均存在多次检测到的 QTL 区段。连锁分析和关联分析均显示20号染色体检测到大豆籽粒蛋白质含量 QTL 的频率均最高，且在该染色体上预测了一些大豆籽粒蛋白质含量相关的候选基因，但这些候选基因在染色体上的位置不一致，还需要进一步验证。20号染色体有一个 QTL 区段（A688- Satt239）在多个环境和群体中均检测到，这为高蛋白分子标记辅助育种提供依据，并为后续的深入研究提供参考。

Soybean is an important source of vegetable protein. Soybean molecular genetic advances on seed protein were reviewed in this paper. The results on soybean protein were affected by genetic,environmental factors, and varied widely. According to phenotypic data,significant additive effects were found with heritability from 31%to 99% among different materials. A total of 298 QTLs related to protein content were on each of the 20 chromo-somes. Some QTLs were repeatedly detected on Chro. 20(I linkage group),Chro. 15(E linkage group)and oth-er chromosomes. The 298 QTLs explained 0. 002% to 80% of phenotypic variance. Linkage and association analy-sis showed that Chro. 20(I linkage group)had the highest frequency QTLs. From which,some candidate genes were predicted and further verified. On this linkage group,QTL A688 - Satt239 was detected in multiple environ-ments and populations,and it had great potential in protein molecular marker assisted breeding.
