The sugar beet variety Vivianna KWS possesses pronounced resistance or tolerance to Rhizoctonia, which is confirmed by test results under artificial pathogen infection conditions and the RH label in agronomic documentation.
Data on the variety were recorded in reference materials and registries between 2012 and 2020, where it was evaluated based on root yield indicators and sugar content. Detailed morphological traits and data on parental lines are not available in open sources.
