Abstract
Cyto-morphological studies were conducted on male sterility in yellow and brown sarson. In the post-meiotic stages, the tapetum did not seem to function as a nutritive layer in yellow sarson as it persisted long after degeneration of tetrads. The non-dehiscence of anthers in brown sarson appeared to be due to the presence of large, irregular cells of anther wall in the form of a thick, compact layer. Meiotic studies on these two types of male sterility did not show any abnormality
