Abstract: Paraffin wax section was employed to observe the microsporogenesis of male sterility of onion line 0127A and its maintainer 0127B and their morphological features at different microsporogenesis stages with light microscope. It was shown that male sterility line 0127A microspore abortion occurred in the uninucleate pollen grain stage and during this period cytoplasm of monocytic microspore were decompounded so that the microspore aborted because of lacking nutrition.

Key words: Dnion, Malesterility, Microsporogenesis, Cytomorpholoy
