Abstract: 

Some different sources of cytoplasmic male sterility (CMS) have been described in beets. Up to now, hybrid seed production in the sugar beet has exclusively relied on Owen CMS. Discovery of Owen CMS in a sugar beet cultivar has played an important role in the development of hybrid cultivars and changed breeding methods in sugar beet. Hybrid plant cultivars carrying CMS Owen are semi fertile. The aims of this research were to evaluate cytoplasm variation and to determine cytoplasmic male sterility source used in production of new cultivars. Mitochondrial minisatellites and CAPS marker were used. Banding profiles of four cultivars and two male sterile and fertile lines demonstrated the presence of Owen CMS in breeding procedures of these cultivars. Cytoplasmic variation was not observed between cultivars, but more than half of progeny derived by crossing a cultivar plants with SHR01-P12 pollinator plants was sterile. It seems, other nucleus gene (s) besides Owen CMS have been used in producing some new hybrid cultivars.
