We have observed that Albugo candida causes white, foam-like, slightly raised spots of various size and irregular shapes on the leaves. The infection can have different levels in different varieties and the differences were shown in the morphological complexes, too. The leaves of Danvit, Norda, Eperjesi-1 and Westsik-telep 5 varieties were not infected with Albugo candida. Szakácsi was infected moderately, Pózna and Pellérdi were strongly infected. The fungus infection of the other varieties and strains was weak.
The varieties of “dán” morhological complex got infected least of all, while the varieties of” spreewaldi” became infected the most. The size of spot symptoms ranges from pinprick to 20 mm diameter. The former is typical in the “spreewaldi”, the latter in the “dán” morphological complex, but we found no clear correlation between the number and size of patches of infection. Varieties vary in the size of conidia, but it is not related to either the different morphological complexes, nor the rate of infection.
