Abstrakt: By means of DNA markers of potato golden nematode resistance genes H1 and Gro1, 109 Russian- and foreign-bred potato varieties are assessed. A sufficiently high level of coincidence of the presence of marker alleles with phenotypic resistance of potato varieties is revealed. However, not all resistant forms have specific amplification products. The use of DNA markers of only two genes H1 and Gro1 will not make it possible to completely replace mass laboratory testing, but it will make it possible to select potato forms resistant to this parasite by a simple and reliable method in a shorter time and thereby to considerably reduce the number of genotypes in the sample for further breeding.
