大豆亚属是栽培大豆及其祖先的姊妹类群，几十年来已经接受了大量研究。生物系统数据和广泛的种质资源的结合为该小组的分子系统研究（包括异源多倍体的研究）提供了坚实的基础。这些研究表明，该亚属已知的各种多倍体类群都是单个大型异源多倍体复合体的一部分，通过共享的二倍体基因组连接。该复合体的许多元素都是最近出现的，并且大多数都显示出重复起源的证据。然而，即使是密切相关的多倍体之间也存在许多差异。多倍体在以下方面彼此不同：起源数量、不同基因座所具有的等位基因多样性数量、双向起源与单向起源、核糖体基因同源物的保留、通过地理范围和丰度衡量的成功以及基因表达模式。 (C) 2004 年伦敦林奈学会。
Glycine subgenus Glycine, the sister group to the cultivated soybean and its progenitor, have received considerable study over several decades. The combination of biosystematic data and an extensive germplasm collection has provided a strong foundation for molecular systematic studies in the group, including those on allopolyploids. These studies have shown that the various polyploid taxa known from the subgenus are all part of a single large allopolyploid complex, linked by shared diploid genomes. Many elements of the complex have arisen recently, and most show evidence of recurrent origins. However, there are also many dissimilarities among even closely related polyploids. Polyploids differ from one another in such ways as number of origins, amount of allelic diversity harboured at different loci, bidirectional vs. unidirectional origins, retention of ribosomal gene homoeologues, success as measured by geographical range and abundance, and patterns of gene expression.
