| Title : | FEATURES OF CHEMICAL COMPOSITION AND TECHNOLOGICAL CHARACTERISTICS OF ROOT OF SUGAR BEET GENOTYPES |
| Abstract : | Sugar beet breeding aimed at improving root processability involves the selection of breeding genotypes for the content of harmful non-sugars − K+, Na+, non-protein nitrogen − directly affecting the technological white sugar yield. The relevant are the researches on the chemical composition of plant organs of sugar beet breeding genotypes, including the content and patterns of ash, macro- and micronutrients, nitrogenous and insoluble substances distribution in order to improve beet processability. As a result of vegetation and field experiments, significant genotypic differences of the pectin substances content in sugar beet roots of Ukrainian and foreign breeding were found. The dynamics of accumulation of various forms of pectin substances in ontogenesis and the phase of development of sugar beet with the maximum accumulation of pectin and protopectin in roots were detected. The studied sugar beet genotypes were cultivated in different soil-climatic zones of the Forest-Steppe of Ukraine. Dependence of the increase in the content of pectin substances in roots from the northwest to the southeast was found. The regularities of changes in technological quality indicators during long-term storage of roots and their affection by phytopathogenic microorganisms were studied. It was proved that hybrids of foreign breeding accumulated significantly more reducing sugars and soluble nitrogenous substances during storage, which negatively affected the juice purity and increased the loss of sucrose in molasses. It was shown that varieties and hybrids of Ukrainian breeding and the hybrid Taltos (Belgian breeding) were the most resistant to affection by phytopathogenic microorganisms. Hybrids of German and Swedish breeding were characterized by a high content of rotten mass. |
