      abstract     = {Cercospora leaf spot (CLS) infection can cause severe yield
                      loss in sugar beet. Introduction of Cercospora-resistant
                      varieties in breeding programmes is important for plant
                      protection to reduce both fungicide applications and the
                      risk of the development of fungal resistance. However, in
                      vivo monitoring of the sugar-containing taproots at early
                      stages of foliar symptoms and the characterization of the
                      temporal development of disease progression has proven
                      difficult. Non-invasive magnetic resonance imaging (MRI)
                      measurements were conducted to quantify taproot development
                      of genotypes with high (HS) and low (LS) levels of
                      susceptibility after foliar Cercospora inoculation. Fourteen
                      days post-inoculation (dpi) the ratio of infected leaf area
                      was still low $(~7\%)$ in both the HS and LS genotypes.
                      However, during this period, the volumetric growth of the
                      taproot had already started to decrease. Additionally,
                      inoculated plants showed a reduction of the increase in
                      width of inner cambial rings while the width of outer rings
                      increased slightly compared with non-inoculated plants. This
                      response partly compensated for the reduced development of
                      inner rings that had a vascular connection with
                      Cercospora-inoculated leaves. Hence, alterations in taproot
                      anatomical features such as volume and cambial ring
                      development can be non-invasively detected already at 14
                      dpi, providing information on the early impact of the
                      infection on whole-plant performance. All these findings
                      show that MRI is a suitable tool to identify promising
                      candidate parent lines with improved resistance to
                      Cercospora, for example with comparatively lower taproot
                      growth reduction at early stages of canopy infection, for
                      future introduction into breeing programmes.},
