Marker assisted selection (MAS) in potato breeding is the most developing area at present time. Methods of DNA markers are developed in all top world potato research institutes and universities oriented on plant production. This paper presents results obtained from the testing of gene resources encompassing different resistance genes against Phytophthora infestans potentially exploitable for Czech potato breeding. Three different DNA markers were studied that are linked to R1 locus in the potato chromosome V operating as a resistance against some races of P. infestans. Markering capability and frequencies of these markers was evaluated with respect to their usage in practical Czech plant breeding that has vital importance in finding the tools as a prerequisite for creating new varieties efficiently.
