Abstract

Potato wart (Synchytrium endobioticum) is a very important quarantine disease worldwide. The disease was first found in Georgia in 2009. Because of the unreliable chemical control to eliminate the pest in the soil, it is applicable to cultivate potato varieties resistant to the pathotypes present in the infested plots. To prevent the disease spread, it is very important to test imported potatoes for the resistance to the disease before commercially releasing them in fields. The preliminary assessment of introduced commercial potato cultivars for resistance to potato wart in infested plots was carried out using the field test in Skvana and Uchkho villages, and the pot test for Didajara village in Khulo municipality. As a result of screening, potato cultivars showed the different reactions to potato wart in field and pot tests. The majority of the tested cultivars were susceptible to the wart and only several cultivars showed resistance in separate tests.
