With the purpose of creation of parental forms for a confectionary hybrid variety the thirty three large-seed sunflower accessions of the VIR collection were analyzed for the presence of the Rf1 gene marker. As a result of research the presence of the SCAR-marker Y10 among the studied confectionery sunflower varieties is confirmed. The examined accessions were conventionally divided into 4 groups. In the first group the marker was present in more than 50% of the studied of plants. In the second the marker was found in 20-50% of the plants. In the third group the marker was observed in 10-20% of the plants, and in the fourth group all the plants were without marker. The second group includes accessions SPK, Lakomka, Borodinskiy, Donskoy krupnoplodnyi. The first group included 9 accessions and the three of them the of plants with the marker constituted more than 90%.
