| Summary: | The results of molecular screening of 103 Russian breeding varieties from the VIR potato collection are presented. These varieties were studied for the presence of diagnostic markers associated with the HI and Grol-4 genes conferring resistance to the golden potato cyst nematode - Globodera rostochiensis (Woll.) Behr. - pathotype Ro1. 25 varieties possessed the diagnostic markers of these genes. Among the nematode-resistant varieties, the frequency of genotypes with the diagnostic fragments of 57R and N195 markers of the Hl locus was 98%, and of marker Gro1-4-1 of the Grol-4 gene - 2%. |
