大豆隐性核不育应用于大豆群体改良能大大地减少人工杂交，获得大量杂种，提高群体个体间的异交率，从而提高群体改良的效率。本文着重探讨了利用大豆雄性隐性核不育基因合成基础群体及进行轮回选择的方法与技术，以期指导群体改良研究 Soybean recessive nuclear sterility applied to the improvement of soybean population can greatly reduce the artificial hybridization, access to a large number of hybrids, improve the rate of outcrossing among groups of individuals, thereby improving the efficiency of population improvement. This article focuses on the use of soybean male recessive genic male sterility gene synthesis and selection of the basic methods and techniques to guide the group to improve the study
