Abstract: In the years 2005 and 2006 the effect of site conditions, yellow and purple fleshed varieties and mineral fertilization on the content of total polyphenols (TP) in potato tubers was investigated. In both years significantly the highest TP content (by 5.7 to 56.3% higher than in other localities) was determined at the Stachy locality; we ascribe it to apparently lower temperatures in the vegetation period at this locality of higher altitude. In the purple flesh Valfi variety TP content higher by 74 to 141% was recorded in average of both years, in comparison to yellow flesh varieties. In the group of eight yellow flesh varieties the highest TP content was recorded in the Ditta variety; it was higher by 38, 29 and 24% in comparison with Saturna, Agria and Asterix varieties. TP content was not significantly affected by fertilization with mineral fertilizers.
