Comparative morphological and cytological studies were made of anthers from a male-sterile and male-fertile line and a male-sterile and a male-fertile Ft hybrid of Sudangrass, Sorghum vulgare var. sudanense. Meiosis was normal in both male-fertile and male-sterile lines and normal tetrads were formed. Pollen abortion in male-sterile lines was associated with non-degeneration of the tapetal cells during the maturation of the young microspores, whereas, tapetal cells degenerated during similar maturation stages with production of normal pollen in malefertile lines.
