ESTIMATION OF RESISTANCE OF BREEDING NUMBERS OF SUGAR BEET TO LEAF DISEASES

The article deals with the resistance of CMS hybrids, tetraploid and diploid forms of sugar beet to cercosporosis and erysiphosis. There was determined that diploid materials are less resistant than tetraploid ones, and variability in diseases degree was estimated during several years. Perspective materials for hybrids which can be used in bio-adaptive technology were selected.

INCREASED NUTRITION AREA AS A MODIFIING FACTOR OF FENOTYPICAL SHOW OF SUGAR CONTENT OF MS LINES AND FIXING AGENTS OF STERILITY IN SUGAR BEET

The article shows the results of the research of the influence of increased nutrition area on sugar content and sugar crop in MS lines and sterility fixing lines of sugar beet. It is determined specific reaction of genotypes to modifying factor, its most essential influence on characteristics variability, most perspective materials for formation of simple sterile hybrids as mother components have been chosen.
