New Races

Downy mildew of sunflower (Helianthus annuus L.) incitated by Plasmopara halstedii is a potentially devastating disease. We report here the finding of two new races of P. halstedii and also two Apron35S fungicide-resistant isolates of race A. Using the random amplified polymorphic DNA (RAPD) technique as an initial screening for genetic variation within P. halstedii French races, genetic variation was not found between isolates within races 1, A, or B, and very few polymorphisms were distinguished between all French races known today.Key words: Plasmopara halstedii, race, genetic variability, RAPD.
