The aphid-transmissible viruses leading to yellowing disease of sugar beet can no longer be controlled after the ban of the neonicotinoid seed treatment. The project aim was to pave the way for the development of alternative integrated control measures and to support breeding in the development of resistance breeding programmes. Methods for the culture and maintenance of virus species were established and made usable for bioassays. The temporal and tissue-specific spread of the virus species in sugar beet was studied to provide breeders with biomarkers for the development of a resistance selection methodology. A method for producing virus-infected vectors in large numbers for inoculation of field trials could be developed. In field trials, the yield risk of the individual virus species could be determined under near-natural infection conditions. The yield effect is so significant for each of the virus species that genotypic differences in the area of quantitative resistance/tolerance can be reliably mapped under practical field trial conditions.
