| Abstract | Implementation of intensive technology of sugar beet production, that provides final density of sowing, which could be possible only with availability of high quality seeds that are not only a carrier of variety or hybrid productivity, but are also an important element of sugar beets growing technology. In recent years, demands for quality of seed increased significantly: at the beginning of this century for sugar beet growing was enough to have the seed with germination indices of 80-85% and monospermous of 85%, at the moment these indices should be not less than 92 and 95%, respectively. With the help of studying influence of diameter of fruits fraction and degree of monogermity of elite seeds of hybrids MS components on sowing qualities and productive quality of hybrid seeds was found that the seeds fraction size in the interval of 3,00-5,50 mm and seed percentage had no significant effect on hybrid seed sowing qualities: growing energy varies within 73-83%, germination – 86-97%. Concerning seed influence, it is necessary to note the influence of its index both on sterility level and conditioned seed yield 3.5 – 5.5 mm fraction. However, hybrids sown by hybrid seeds of non-standard fraction of 3,0-3,75 mm diameter, unsized seeds had lower yield, compared with 3.5-4.5 and 4.5 -5.5 mm fractions. Level of seeds monogermity of MS component elite does not affect on hybrids productivity indexes that according to the research results veries within LSD05. | ||
