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
