A cytological comparison of pollen and tapetal development from fertile and male-sterile garden beet (Beta vulgaris L.) lines, has indicated that microsporogenesis was normal and malesterility was manifested during microgametogenesis. Fertile plants developed trinucleate pollen grains and tapetum cells were of secretory type. In male-sterile plants development of pollen ended at the one-nucleate stage, while formation of periplasmodium from tapetum cells took place. The anthers of both plants had a mature endothecium with fibrous wall thickenings well developed.
