Abstract: Through ultra-structure observation, it was found that the microspore of D-type cms line began to abort in “small vacuole” stage. During the abortion period of the cms line, the vacuolar membrane and cell membrane of microspore dissolved, cytoplasm degenerated, the cell organelles such as mitochon
