The paper shows the results of many-year activities on the creation of a new generation of sunflower hybrids, high-yielding, resistant to main diseases’ pathogens. The system of infection backgrounds developed in Plant Production Institute nd. a. V. Ya. Yuriev of National Academy of Agrarian Sciences of Ukraine is an inseparable part of the process of sunflower hybrid breeding. The system includes field and laboratory investigations on resistance to the most harmful diseases of sunflower on natural, artificial and provocative infection. Immunological evaluation and differentiation of the breeding material as to the resistance to the pathogens of phomopsis, bud-rot and cottony rot and broomrape under artificial field infection, green-house-field method of infection and sunflower infection evaluation with false downy mildew’s pathogen and broomrape have permitted to identify the variety-samples – sources of genetically conditioned resistance to main pathogens. Special attention is paid to the problem of combination of the resistance to disease pathogens and high indices of productivity in one genotype. The sunflower hybrids recommended for cultivation, with group resistance to disease pathogens and broomrape have resulted from many-year activitiesDownloads
