摘 要 ：本文首次报道了发生于香蕉小孢子母细胞减数分裂中的一种异常现象：部分染色体在中期Ｉ发生单价体提早分离。这可能是异源多倍体中不同源染色体组的异质性所引起．

Abstract:An abnormal Phenomenon of meiosis in Potion mother cell of ghana is reported for the first time. The principal character of the meiosis is that the two chromatids of some univalents separate early in metaphase. The authors suggest that this might be caused by the allogenic genomes which can not synchronize in meiosis. The origin of banana Gaozhouai is also discussed
