栽培大豆品种间杂交组合Ｎ８８５５×Ｎ２８９９ 的Ｆ１ 表现雄性不育，经与Ｎ２８９９ 连续回交４ 代，选育出综合农艺性状优良、花粉败育率为１００％ 的大豆质核互作雄性不育系ＮＪＣＭＳ１Ａ及其保持系ＮＪＣＭＳ１Ｂ。不育系雌性育性正常，在不同环境条件下雄性不育性稳定。在回交世代ＢＣ１Ｆ１、ＢＣ２Ｆ１ 不育株中发现个别花内含有２ 个雌蕊（周围２０ 个雄蕊）、３ 个雌蕊（周围３０ 个雄蕊）等异常现象
F1 hybrids of cultivated soybean varieties N8855 × N2899 were male sterile, and backcrossed with N2899 for 4 generations. Breeding of CMS lines with excellent agronomic characters and pollination abortion rate of 100% NJCMS1A and its maintainer line NJCMS1B. Female fertility normal fertility, male sterility in different environmental conditions and stability. In backcross generations BC1F1, BC2F1 sterile plants were found in individual flowers containing 2 pistils (around the 20 stamens), 3 pistils (around the 30 stamens) and other anomalies
