Artificial infection of 1st year potato seedlings with PVS and PVM viruses and selection of resistant samples

The results of a study on artificial infection of 1st year seedlings with PVS and PVM viruses in hybrid populations of potatoes obtained from crossing isolated parental forms with the presence of resistance genes – Ns, Rm and Gm – in their genotype based on DNA marking are presented. As a result of the research, susceptible seedlings were culled and hybrid populations with a high percentage of potato samples relatively resistant to PVS and PVM were isolated. For further study and selection development in field nurseries, 1012 hybrid descendants were selected that were relatively resistant to the pathogens under study.
