Abstract

In the years 2008–2011, in the Department of Potato Protection and Seed Science in Bonin, we carried out a series of laboratory tests assessing the levels of resistance to: tuber wet rot, dry rot and late blight of potato tubers of 25 chosen potato cultivars, registered in 2005–2008. In the conducted tests we did not find varieties resistant at the same time to all evaluated diseases. Among the tested varieties, the most were resistant to tuber dry rot and only few to potato late blight. Among the varieties tested in the group of very early and early, Annabelle showed a low susceptibility to wet and dry rot, and sensitivity to the potato late blight. Medium early variety Agnes was sensitive to wet and dry rot, and weakly susceptible to P. infestans and late variety Niagara turned out to be susceptible to dry rot and potato late blight.
