摘要
It has been suggested that the soybean (Glycine max [L.] Merr.) currently cultivated in commercial agriculture was domesticated from the wild soybean (G. soja Sieb. & Zucc.) in China approximately 5,000 years ago. Because of its high protein and oil content, cultivated soybean has become a major economic crop by providing 69% and 30% of the world's plant protein and oil. Soybean breeders have made considerable efforts to develop elite varieties that can meet this ever-increasing demand. However, over the last century, advances in soybean breeding have progressed slowly. One of the major reasons is the genetic bottlenecks caused by the domestication practice of using seeds from only a small number of plants with desirable traits to propagate each new generation during introduction and im- provement [1]. Well-established genome sequences and a better understanding of the underlying genetic bases of agronomically important traits will expedite the progress of marker-assisted breeding programs for soybean.
