Abstract

Eight red chicory (Cichorium intybus L. var. silvestre Bisch.) cultivars were screened for plant characteristics, yield, resistance to Erysiphe cichoracearum and their persistence of bolting over a two-year period (2002 and 2003 growing seasons) in central Slovenia. On two years with meteorologically different conditions the highest total and marketable weight of heads (i.e. total weight – weight of removed damaged leaves) were obtained from cv. 'Averto', followed by cv. 'Mesola' and 'Rubino'. The most compact heads in both years, were produced by cv. 'Palla rossa-super'. Less productive cultivars of red chicory were on average the most infected with the powdery mildew caused by E. cichoracearum. In 2002 the fungus occurred in a substantially larger extent than in 2003, which was less favourable for spread of the pathogen. The higher temperatures, prevailing in summer 2003, presumably promoted a greater percentage of bolting in plants. Among eight cultivars studied through two years, cv. 'Castel Franco', 'Averto' and 'Mesola' drew no incidence of bolters.
