The aim of the undertaken studies was to determine the effect of the herbicides used in the experiment on important features of the consumption values of three varieties of edible potato. Test results come from a field experiment conducted in 2007–2010. The experiment was established as two-factor in the split-plot system in three repetitions. Two factors were tested in the experiment: factor I - potato varieties: Satina, Tajfun, Cekin; factor II – five methods of weed control. Darkening of the pulp of cooked tubers after 10 min, 2 and 24 hours shape the ways of weed control of the plantation and the genotype of the grown varieties. The use of herbicides in 2–5 variants has significantly increased the darkening of the pulp. The Tajfun variation darkened to the lowest degree, and Cekin to the largest degree.
