The object of research is lines, populations, collection samples, varieties, hybrids of sugar beets. The subject of research is the theoretical basis of creating new varieties forms of sugar beets and improving the methodology of their evaluation. The purpose of the research is to develop the theoretical basis for the creation of new initial forms of sugar beets and the selection of desirable genotypes of plants of the species Beta vulgaris L. for selection for productivity. The research methods are laboratory, field, measuring and weighing, statistical. Theoretical foundations were developed and a new raw material of sugar beets with improved quantitative and qualitative selection-genetic and economic-valuable traits was created for the selection of parental components of hybrids on the basis of CMS. Fundamentally new source selection materials for sugar beets (O-type lines and their analogues from the Central Agricultural System, 2xMM and 4xMM pollinators) and methods of their production were introduced into the selection process, donors of high yield and sugar content of root crops, improved shape of the root crop, technological quality of sugar raw material, resistance to diseases and stressful environmental conditions. Key words: sugar beet, hybrid, line, population, combining ability, heterosis, crossing, selection, sterility, fertility, fecundity, ploidy, productivity, sugar content, technological quality.
