The studies on the anther ontogeny of five cytoplasmic male-sterile lines withcomparision of fertile lines in radish seems to be indicated that these male-sterile materilesmay be divided into two types: 1. The inhibition of 475A anther development occurred beforethe stage of male archesproial differentiation. No anther produced four anther loculi. Before itbloom,the anther deformed,many cells shrunk and broken. 2. The inhibition of 134A, 262A,Beijing White A, Spring Red A anther development occurred at the stage of mononuclearpollen. The tapatal cell developed abnormally. In 134A, they highly vacuolated,showed hypertrophy and occupied the loculi. In Spring Red A,their cell walls disappeared and the cellcontents fused to form periplasmodial invading the loculi. Beijing White A and 262A had bothkinds of the tapetal abnormality. With the degeneration of the tapetal cells,pollen aborted.The loculi finally deformed and shrunk,only left little material which stained dark. The vascular system of the male-sterile lines had xylem and phloem,but it was poorly developed ascompared with that of the maintainer.
