Inter-isolate variation for virulence in Plasmopara halstedii (sunflower downy mildew) from Hungary
A total of 82 isolates of Plasmopara halstedii, collected from all production areas of Hungary between 1976 and 1993, were assessed for their virulence pattern on a standard set of sunfiower differentials under glasshouse conditions. The isolates were classified into six pathogenic races each representing a particular virulence phenotyjje. From 1976 until 1988 all the isolates were found to be ...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning

متن کاملComponents of Quantitative Resistance to Downy Mildew (plasmopara Halstedii) in Sunflower (helianthus Annuus)
Components of quantitative resistance in sunflower (Helianthus annuus) to Plasmopara halstedii, the pathogen causing downy mildew, were investigated. Percentage infection, latent period, sporulation density and reduction of hypocotyl length were compared on two sunflower lines showing different levels of quantitative resistance in the field infected with different P. halstedii strains of races ...
