利用８种ＲＡＰＤ引物（ＯＰＨ－２、ＯＰＨ－３、ＯＰＨ－５、ＯＰＨ－１２、ＯＰＨ－１５、ＯＰＨ－１６、ＯＰＨ－１８和ＯＰＨ－２０）对大豆属的２１份植物材料，其中包括Ｇｌｙｃｉｎｅ亚属的１０个种和Ｓｏｊａ亚属的３个种，进行了基因组指纹图谱构建。通过对获得的基因组指纹图谱的量化分析，利用Ｕｎｗｅｉｇｈｔｅｄｐａｉｒｇｒｏｕｐｗｉｔｈｍａｔｈｅｍａｔｉｃａｖｅｒａｇｅ（ＵＰＧＭＡ）对大豆属中的各个种进行了亲缘关系重建。重建的亲缘关系表明：Ｇ．ｔｏｍｅｎｔｅｌｌａ种中存在３种不同的进化类型，其分化距离已大于某些种种间的分化距离，它们可能是被形态遮蔽的３个种。Ｓｏｊａ亚属内３个种的分化关系同前人的研究推断相同，其亲缘关系很近，这一结果支持将这３个种归并为一个种的观点。但是重建的亲缘关系未能显示出大豆属两个亚属的划分格局。
Twenty one parts of Glycyrrhiza plant material, including Glycine, were harvested using eight RAPD primers (OPH-2, OPH-3, OPH-5, OPH-12, OPH-15, OPH-16, OPH-18 and OPH-20) 10 species of subgenus and 3 species of subgenus of Soja were constructed for genomic fingerprinting. Based on the quantitative analysis of the obtained genomic fingerprints, we reconstructed the related species in Glycine by Unweightedpairpairwithmathematicaverage (UPGMA). Reconstruction of the kinship shows: G. There are three different evolutionary types in tomentella. The divergence distance is greater than the divergence distance between some species, which may be three species that are occluded by morphology. The three species of Soja in the subgenus are the same inferred from previous studies, and their genetic relationship is very close. This result supports the idea of combining these three species into one species. However, the genetic relationship of reconstruction failed to show the division pattern of two genera of Soybean.
