The aim - bold forms of fodder beet, providing high combining ability with high display signs single-germ and seed viability and result in creation of highly monogerm varieties suitable for cultivation with minimal manual labor. Research methods - laboratory and field using hybridization saturating crosses, inbreeding and selection. In studies conducted studied several cross-pollination of different origin-seeded forms of fodder beet affect the compatibility level of parental gametes, which should positively influence the development of adequate seeds and ascertain the possible causes that affect the decrease in seed germination. The results showed that the performance of seed germination seeded numbers of fodder beet are characterized by low levels of seed viability obtained as an isolated breeding and nursery in polikrossu. Analysis of diverse fetus showed that the presence of such degenerativeembryo sacs and embryos degenerated may indicate that we still could not get rid of the negative impact of system incompatibility genes. One can only note that the percentage of fetus down from isolated breeding mating components and a significant reduction in seed viability was due to dying embryos at later stages of embryogenesis. As a result of this work was made and transfered to the State variety testing variety of oneseed mangel Kozak with amount of separately flowers 98 % and with increase contain of dry matter. Using hybridization techniques, various forms of inbreeding and selection create monogerm new materials for further breeding.
