The aim - to find out what effect does cross-pollination seeded materials into a hotbed polikrossu on indicators and viability of seeds. Research methods - laboratory and field using hybridization saturating crosses, inbreeding and selection. Performed breeding program varieties of synthetic with a broad genetic base, which should have a positive impact on the viability of embryos and through it on the germination of seeds. Work has begun to assess the combination of the components of such varieties and study the possibility of increasing the survival of seed embryos in synthetic varieties by maintaining a balance of subvitalnyh genes, which in the reporting year was 6 schemes polikrosnih crosses. As a result, studies the biological characteristics of the formation of viable seeds in seeded fodder beet revealed a significant portion of fetus (21,1-56,5%) of degenerative embryo sac, which may be due to lack of pollination, genetic incompatibility pollen tubes of pistils stigmas at heytenohamnomu pollination, or at the xenogamy when gametes are identical S-genes. In 2012, 25 hybrid combinations were analyzed 3-5 generations of the pair crosses represented 380 plants. In 2012, 25 hybrid combinations were analyzed 3-5 generations from the pair crosses represented 380 plants. In the 17 hybrids showed complete all descendants monogerm and in the 8 hybrids met except seeded plants with incomplete monogerm that defective. Increasing the share of monogerm aggregate fetus paired crosses completely seeded plants demonstrates the need for the use of self-pollination and double crosses only fully monogerm plants. Through repeated selection on the basis of hybrids from crosses seeded forms polyspermous received a number of numbers that are on the basis of performance exceed the previously created seeded standard grade Daria (18.5 - 22.1), but inferior to the standard multi-seeded varieties Sonnet.
