Characterization of resistance mechanisms to powdery mildew (Erysiphe betae) in beet (Beta vulgaris).
Beet powdery mildew incited by Erysiphe betae is a serious foliar fungal disease of worldwide distribution causing losses of up to 30%. In the present work, we searched for resistance in a germplasm collection of 184 genotypes of Beta vulgaris including fodder (51 genotypes), garden (60 genotypes), leaf (51 genotypes), and sugar (22 genotypes) beet types. Resistant genotypes were identified in ...
متن کاملComparison of ITS sequences from UK and North American sugar-beet powdery mildews and the designation of Erysiphe betae.
Powdery mildew of sugar beet, a disease of major economic significance, was first described at the beginning of the 20th century, and since then there has been some confusion over the correct taxonomic identity of the causal agent. In Europe, the fungus was initially classified as the novel species Microsphaera betae, later re-named Erysiphe betae, whilst in America it was identified as E. poly...
متن کاملa study on genetic diversity of iranian populations of erysiphe betae(vanha) weltzien causal agent of sugar beet powdery mildew using rdna-rflp method
a total of 105 isolates of erysiphe betae from different regions of iran were investigated. for probable polymorphism of its-5.8s regions using pcr-based rflp, the mentioned fragments were amplified via pcr by its1 and its4 primers and subjected to 1.5% agarose gel electrophoresis. pcr products were digested by haeiii, alui, taqi, hindiii, cfoi, ecori, mspi, saci and rsai res and the digestion ...
متن کاملEffects of Bunch Rot (Botrytis cinerea) and Powdery Mildew (Erysiphe necator) Fungal Diseases on Wine Aroma
This study aimed to characterize the effects of bunch rot and powdery mildew on the primary quality parameter of wine, the aroma. The influence of these fungal diseases was studied by comparative Aroma Extract Dilution Analyses (AEDA) and sensory tests. The effect of bunch rot was investigated on three grape varieties, namely White Riesling, Red Riesling and Gewürztraminer and that of powdery m...
متن کاملFluorescence Indices for the Proximal Sensing of Powdery Mildew, Nitrogen Supply and Water Deficit in Sugar Beet Leaves
Using potted sugar beet plants we aimed to investigate the suitability of four fluorescence indices to detect and differentiate the impact of nitrogen supply, water deficit and powdery mildew in two sugar beet cultivars (Beta vulgaris L.). Plants were grown inside a polytunnel under two nitrogen levels combined with water deficit or full irrigation. Changes in plant physiology were recorded at ...
