Modern conception about the structure and development of sunflower anther in the normal state and under the different types of sterility are presented in the investigation. In the review different types of male sterility: nuclear male sterility, cytoplasmic male sterility and sterility which induces different factors is considered. This research is based on the scientific literature summarizing and experimental work results of the authors as for meiosis studying of culture sunflower and wild species and their interspecific hybrids. Spore formation capacity of androceum concerning practical breeding and seed production problems are also stated. The results of research in field of inheritance of nuclear mail sterility and cytoplasmic mail sterility, mapping of genes which control male sterility with use different molecular markers. The questions of relationship plasmone and genome in manifestation of cytoplasmic male sterility were showed. The importance of gametocytes for the induce of sunflower sterility was considered. A great attention is paid to meiosis violation in the process of chromosome formation rearrangement during the interspecific hybridization. The reasons of cytological instability of interspecific hybrids which have been obtained by crossing of annual wild species with culture sunflower and the ways of overcoming this cytological instability are discussed.
