Abstract: Sunflower is one of the most important oil crops, the cultivation of which is hampered significantly by the pathogen of downy mildew (Plasmopara halstedii (Farl.) Berl. et de Toni). Currently, the gen Plarg responsible for resistance to all known races of P. halstedii is promising for breeding. The diagnostic value of SNP-marker NSA_006530 is determined basing on the hybrid analysis of F2 in a segregating hybrid population ВК-925 × RHA-419. The genetic distance by Kosambi between studied pair of loci 28.85 сМ showed the linked inheritance of the gene Plarg and a locus NSA_006530. The studied marker was validated on sunflower lines from a collection of the V.S. Pustovoit All-Russian Research Institute of Oil Crops.
