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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
