春大豆雄性核不育基础群体构建与轮回选择育种技术

Spring Soybean Based Groups to Build Nuclear Male Sterile and Recurrent Selection Breeding Technology

摘要: 大豆ms1核不育轮回群体选择育种技术作为种质创新的方法在大豆新种质创新方面有着广泛的应用。大豆ms1核不育基因实现了大豆的开放授粉、基因聚集、积累，丰富了群体的遗传多样性。本文介绍了宁夏春大豆雄性核不育种质基因库基础群体的构建，大豆ms1核不育轮回选择育种技术及取得的效果。大豆种质基因库基础群体及轮回选择技术为宁夏春大豆新品种选育奠定了的基础。

Abstract: Soybean ms1 cycle of nuclear male sterility group selection breeding techniques as a way of germplasm innovation in new soybean germplasm innovation has been widely used. Soybean ms1 nuclear male sterility gene has realized the soybean open pollination, gene gathering and accumu-lation, and enriched the genetic diversity of population. This paper introduced the foundation of Ningxia spring soybean based group nuclear male sterile germplasm gene bank, soybean ms1 nu-clear male sterility and the new technology of recurrent selection breeding. Soybean germplasm gene bank group and recurrent selection technology laid the foundation for Ningxia spring soybean varieties breeding.
