雄性不育是指植物的雄蕊不能正常生长并产生有活力的花粉粒的现象。利用水稻雄性不育特性进行杂交制种是提高作物产量的一种有效而快捷的策略。目前，水稻产量，玉米（Zea mays L.），小麦（Triticum aestivum L.）和其它作物的优势利用率大大提高。大豆（Glycine max（L.）男子）是一种自花授粉的物种，人工去雄不仅费时，而且劳动强度大，经济上不可行。由于缺乏适合于杂交生产的雄性不育系，至今尚未进行大规模的大豆杂交育种。因此，寻找稳定的大豆雄性不育系，以快速利用大豆杂种优势是当务之急。本文综述了大豆核雄性不育突变体和核雄性不育基因的发现进展。结合拟南芥、水稻和玉米中的核不育基因的研究，从反向遗传学的角度为大豆核不育基因的鉴定和利用提供了重要的参考。
Male sterility refers to the phenomenon that stamens cannot grow normally and produce viable pollen grains in plants. Hybrid seed production by taking advantage of the trait of male sterility is an effective and quick strategy to increase crop yield. Up to date, the yield of rice (Oryza sativa L.), maize (Zea mays L.), wheat (Triticum aestivum L.) and other crops has been greatly increased based on hybrid vigor utilization. Soybean (Glycine max (L.) Men.) is a self-pollination species, artificial emasculation is not only time-consuming, but also labor-intensive and economically impracticable. So far, large scale hybrid breeding has not been performed in soybean due to the shortage of male sterile lines suitable for hybrid production. Therefore, it is urgent to identify a stable male sterile system for the rapid utilization of heterosis in soybean. In this review, we summarize the progress on the discovery of soybean genic male sterility (GMS) mutants and GMS genes. Combining with the investigation of GMS genes in Arabidopsis, rice and maize, we provide important insights into the identification and potential utilization of GMS genes in soybean in the perspective of reverse genetics.
