ABSTRACT
In order to understand the cytological mechanism of pollen abortion of genetic male sterile mutant induced by space flight in maize, the sister cross population were used for sterility analysis and cytological observation. Intact anther observation, isolated cells observation and paraffin section were adopted in this research. The results showed that pollen abortion occured mostly in dyad stage of meiosis in genetic male sterile mutant. The dyad were degenerated with abnormal shape. In late anther developing stage, the tapetal cells were giant vacuolated and delayed degeneration. The pollen mother cells (PMC) began to dissolve and degenerate in a few anther before meiosis.
