In this thesis, the effects of year, variety and size of seed tubers on yield and quality of potato tubers were evaluated. In the two years (2011 and 2012), four potato varieties (Velox, Marabel, Adéla and Laura) were used. Size of seed tubers for all varieties was split into three size fractions: A < 35 mm, B 35-60 mm and C > 60 mm. In both years of observation were monitored following parameters: total and marketable yield, average number of stems per plant, number of tubers per plant, number of tubers per stem, the average weight of tuber, proportion of tuber size in harvested tubers, content of dry matter and starch in tubers fresh matter. Year contributed most to the total variability in total and market tuber yield (51.2%. And 54.4%, respectively). Size of seed tubers showed the highest proportion in the total variability of number of stems per plant (94.7%). Declared cooking type in all evaluated varieties was kept. Table value was significantly affected only by variety.
