Hybrid breeding can help us to meet the challenge of feeding a growing world population with limited agricultural land. The demand for soybean is expected to grow; however, the hybrid soybean is still in the process of commercialization even though considerable progress has been made in soybean genome and genetic studies in recent years. Here, we summarize recent advances in male sterility-based breeding programs and the current status of hybrid soybean breeding. A number of male-sterile lines with cytoplasmic male sterility (CMS), genic-controlled photoperiod/thermo-sensitive male sterility, and stable nuclear male sterility (GMS) have been identified in soybean. More than 40 hybrid soybean varieties have been bred using the CMS three-line hybrid system and the cultivation of hybrid soybean is still under way. The key to accelerating hybrid soybean breeding is to increase the out-crossing rate in an economical way. This review outlines current problems with the hybrid soybean breeding systems and explores the current efforts to make the hybrid soybean a commercial success.
杂交育种有助于我们应对在有限耕地条件下养活不断增长的世界人口这一挑战。预计对大豆的需求将会增长;然而,尽管近年来大豆基因组和遗传研究取得了相当大的进展,但杂交大豆仍处于商业化进程中。在此,我们总结了基于雄性不育的育种计划的最新进展以及杂交大豆育种的现状。在大豆中已鉴定出许多具有细胞质雄性不育(CMS)、基因控制的光周期/温敏雄性不育和稳定的核雄性不育(GMS)的雄性不育系。利用CMS三系杂交系统已培育出40多个杂交大豆品种,杂交大豆的种植仍在进行中。加速杂交大豆育种的关键是以经济的方式提高异交率。本综述概述了杂交大豆育种系统目前存在的问题,并探讨了当前为使杂交大豆取得商业成功所做的努力。
