A light and electron microscopic investigation revealed that ogu cytoplasmic male sterility (CMS) in cybrids of Brassica napus is primarily a deficiency of the tapetum and clearly time and site specific. Three patterns of ogu CMS were found, and specific conclusions drawn. First, the partially male fertile cybrid 23 was highly variable. It sometimes produced heterogeneous stamens with an endothecium formed exclusively around the fertile locules, thus delineating each microsporangium as a functional unit. The second type, including cybrids 27,58 and 85, on the contrary, was stable and completely male sterile.
