COMPARING THE PRODUCTIVITY OF SUGAR BEET BREEDING MATERIAL

М.А. Богомолов, Т.В. Вострикова

Abstract


The purpose of the study was to evaluate the productivity of male-sterile forms and hybrids of sugar beet varieties resulting from domestic and foreign breeding. The characteristics taken into account were: yield, sugar content, and sugar yield. Male-sterile specimen selected for their combinatorial abilities and crossed with wild-type specimen irradiated to increase the rate of useful recombination as well hybrids selected in Russia and abroad were used as starting materials. Hybrids not always had characteristic that were better than the parental ones and manifested heterosis. The best characteristics were found in a synthetic pollenizer that surpassed the control variety by 2.5% in crop yield, by 11.4% in sugar content, and by 14.2% in sugar yield. The not so high crop yield of foreign hybrids may be explained with their poor adaptability to conditions prevalent in Central Chernozem area. Domestically breed products are more advisable for farming in this area.
