摘 要 ：通过对大豆雄性不育突变体NJ89-1不育株与可育株小 孢子母细胞减数分裂的比较研究，发现NJ89-1雄性不育株小孢子母细胞减数分裂高度变异，联会异常，出现单价体、染色体落后、染色体桥、染色体不均等分离等；在形成四分体的早期阶段，小孢子母细胞里见到微核，以后产生大小不等的二分体、三分体、四分体及多分体；单核小孢子

Abstract:Comparative studies of the meiosis of the pollen mother cells of the sterile and fertile plants of the new male sterile soybean mutant NJ89-1 showed that the male sterility of NJ89-1 was related to the synaptic variation in meiosis. Meiosis of the pollen mother cell of the sterile plant was highly a
